Do boiled peas undergo cellular respiration?
The high temperature irreversibly destroys crucial proteins in the plant cells, including structural proteins, so the cells fall apart (that's why the water goes green when you boil them) and cease respiration.
Which peas undergo cellular respiration and why?
Why do germinating peas undergo cell respiration? They are growing at a fast rate and need energy to grow, so they use cellular respiration.
Do peas perform photosynthesis?
The pea plant, like all angiosperms, is classified as an autotroph, meaning it uses photosynthesis to convert the energy of the sun to glucose.
Why do germinating peas go under cellular respiration?
Cellular respiration processes provide a means for cells to convert existing nutrient materials into energy. Seeds require necessary energy to develop and grow, so germinating seeds undergo cellular respiration.
Do peas use oxygen in cellular respiration?
Aerobic respiration is the process in which glucose and oxygen, through the action of enzymes in mitochondria, produce carbon dioxide, water and lots of energy. In this experiment the use of oxygen in the aerobic respiration of peas can be seen in that, in a sealed container, the level of oxygen reduces with time.
Why do peas do respiration and not photosynthesis?
The food stored in the seed provides the pea plant cells with the energy they need to maintain themselves and divide, since the plant is not yet capturing sunlight through photosynthesis. The pea plant cells depend on cellular respiration to furnish them with the energy they need to stay alive and grow.
How do peas get energy?
Germinating peas undergo cell respiration in order to supply the energy they need to grow and develop. Cell respiration is the process by which sugars are broken down to release energy. The respired sugars are stored in structures called cotyledons in the pea seed.
Do pea plants give off carbon dioxide?
What does this mean for the number of energy storage molecules in the pea plants? The pea plants can… give off carbon to the air. Giving off carbon allows them to make energy storage molecules.
What are the cellular respiration?
Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Why do dry peas not respire?
The rate of respiration in dormant dry peas is comparatively lower than the rate of respiration in germinating peas. The reason behind this is that in dormant conditions, seeds only require a very small amount of energy which can be used for keeping the cell alive.
Do germinating peas consume oxygen?
The results of this lab show that the germinating peas had consumed more oxygen at a faster rate than the non-germinating peas and the beads had. The non-germinating peas and the beads showed to consume barely any oxygen at all.
Do pea seeds have mitochondria?
Pea Seed Mitochondria Are Endowed with a Remarkable Tolerance to Extreme Physiological Temperatures.
How do you know that peas are undergoing aerobic respiration?
If we wanted to know whether peas were undergoing cellular respiration, we could use an oxygen and carbon dioxide probe to measure the amount of oxygen consumed and the amount of carbon dioxide produced. A decrease in oxygen and an increase in carbon dioxide would be indicative of cellular respiration.
Why do dry peas not respire?
The rate of respiration in dormant dry peas is comparatively lower than the rate of respiration in germinating peas. The reason behind this is that in dormant conditions, seeds only require a very small amount of energy which can be used for keeping the cell alive.
What gas do germinating peas consume during cellular respiration?
During cell respiration the pea seeds will consume O2 and release CO2, but if the CO2 molecules are removed, the result will be fewer molecules of gas. Being that the volume of the container and temperature are constant, then the pressure of the gas inside the respirometer will decrease.
Why do germinating lentils undergo cellular respiration but not photosynthesis?
c)The lentils have stored fuels to drive cellular respiration, but the absence of leaves prevents photosynthesis.
What is the difference between germinating and dormant peas?
Dormant peas do not have favorable environmental conditions, therefore they only need enough ATP to carry out normal processes. Germinating peas ar...
What is the main difference between germinating seeds and non germinating seeds?

Why do germinating peas have a higher respiration rate than non germinating peas?
The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher becau...
Why do germinating seeds have a higher rate of respiration compared to non germinating seeds?
The germinating seeds will have a higher rate of oxygen consumption than the non-germinating seeds because the germinating seeds are living and nee...
Part A: Abstract
This report examines Cellular Respiration and its functions as well as its function in germinating and non-germination peas. Cellular Respiration can best be described as a complicated string of chemical reactions.
Introduction
In this experiment, the goal was to determine the answers to two questions:
Part B
The results were as follows: the germinating peas were producing (0.054 ppt/min of CO2) and consuming (-0.09113 ppt/min of O2), non- germinating peas were producing (0.001037 ppt/min CO2) and consuming (-0.05074 ppt/min O2).
Does cellular respiration occur in peas?
All organisms, including plants and animals, oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. Peas undergo cell respiration during germination.
Why do we use peas for cellular respiration?
Peas will carry out respiration to release the energy needed for growth and heat energy is produced as it is an exothermic reaction. The peas are also covered in microbes which also respire producing heat. The germinating peas which have been disinfected will produce less heat than Flask A.
Does cellular respiration occur in living pea seeds?
Some respiration must occur in order for the seed to live. The rate of cellular respiration will be greater in germinating peas than in dry peas, and temperature will have a direct effect on this rate.Lab 5 Ap Sample 3. Condition Show Calculations Here Rate in mL O2/minute Dry Peas/ 25°C (-0.4 – -0.2) / (26 – 5) -0.01.
What type of plants perform cellular respiration?
Plants have mitochondria and can perform cellular respiration. When would plants need to release energy by cellular respiration? Plants would release energy through cellular respiration in times when sunlight is not present.
How does temperature affect cellular respiration in peas?
The effect of temperature on the rate of cell respiration in the peas is that the higher the temperature, the higher the rate of cell respiration because the cool water causes the enzymes to slow down, causing the reactions of cellular respiration to slow down, and therefore the rate of respiration to be slower.
Why do non germinating peas respire less?
The non-germinating peas shows hardly any consumption of oxygen. Since the germinating peas are germinating or sprouting, they require a more extensive amount of energy or ATP. Therefore, the non-germinating peas have a significantly low rate of respiration in comparison with the germinating peas.
What does cellular respiration produce?
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
What is cellular respiration?
Cellular respiration is a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP), an organic compound the body can use for energy. One molecule of glucose can produce a net of 30-32 ATP.
What is the purpose of cellular respiration?
Cellular respiration is used to generate usable ATP energy in order to support many other reactions in the body. ATP is particularly important for energetically unfavorable reactions that would otherwise not occur without an energy input.
What are the main steps of cellular respiration?
There are three main steps of cellular respiration: glycolysis; the citric acid (TCA) or the Krebs cycle; and the electron transport chain, where oxidative phosphorylation occurs. The TCA cycle and oxidative phosphorylation require oxygen, while glycolysis can occur in anaerobic conditions.
Where does cellular respiration take place?
Cellular respiration takes place in the cytoplasm and mitochondria of each cell of the body. Glycolysis occurs inside the cytoplasm, while the TCA cycle occurs inside the matrix of the mitochondria.
What are the reactants of cellular respiration?
The reactants of cellular respiration vary at each stage, but initially, it requires an input of glucose, ATP, and NAD+. NAD+, a nicotinamide derived from vitamin B3, is a universal electron acceptor that is crucial in the process of cellular respiration. Another important universal electron acceptor is FAD, a flavin nucleotide from vitamin B2.
What are the products of cellular respiration?
The final end products of cellular respiration are ATP and H 2 O. Glycolysis produces two pyruvate molecules, four ATPs (a net of two ATP), two NADH, and two H 2 O. Therefore, without the presence of oxygen, glycolysis is the only process that can occur, and only two ATP molecules may be produced for each glucose molecule.
What are the rate-determining enzymes in cellular respiration?
There are three primary rate-determining enzymes in cellular respiration. These enzymes catalyze the rate-limiting steps, which are the slowest reactions in the series.
