Introduction
- Through an intricate chain of chemical reactions glucose is converted into ATP. This conversion process is called cellular respiration or metabolism.
- Like the exchange of money from one currency to the next, the energy from glucose takes the form of temporary chemical compounds at the end of each reaction. Glucose is changed into several other compounds before its energy settles in ATP. [1]

Which types of molecules are used to create ATP?
It is Adenosine Triphosphate. It is formed by the breakdown of complex molecules like Carbohydrates, Lipids, and Proteins in the process of cellular respiration of the mitochondria. All the substrates are broken down to glucose which then undergoes cellular respiration to liberate ATP.
What types of molecules can be used as a source of energy in cellular respiration?
The primary fuel for cellular respiration is a molecule of glucose, which is used to make energy. In the cellular world, energy is a charged molecule with three phosphate groups called adenosine triphosphate (ATP).
What produces ATP?
Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen. Anaerobic respiration uses chemicals other than oxygen, and this process is primarily used by archaea and bacteria that live in anaerobic environments.
Which molecules can be used for energy?
Adenosine 5'-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups. The word adenosine refers to the adenine plus the ribose sugar.
Which molecule produces the most ATP?
Electron Transport System generates 32 or 34 ATP molecules and is the cell's main source of energy. Thus, the electron transport system produces the most ATP in cellular respiration.
What 3 molecules are made from the process of cellular respiration?
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose.
What are the 3 ways to make ATP?
In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes—glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation—to produce ATP.
What are three sources of ATP?
ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.
Which molecule is critical for ATP production in humans?
Most cells use glucose for ATP synthesis, but there are other fuel molecules equally important for maintaining the body's equilibrium or homeostasis.
What are the 3 most important energy carrier molecules in a cell?
Glucose (C6H12O6,) is a nearly universal fuel delivered to cells, and the primary product of photosynthesis. ATP molecules store smaller amounts of energy and are used within cells to do work. Chlorophyll and NADPH molecules hold energy temporarily during the process of photosynthesis.
Which two energy carrying molecules are used to form glucose?
During cellular respiration, NADH and ATP are used to make glucose. ATP synthase acts as both an enzyme and a channel protein. The carbons from glucose end up in ATP molecules at the end of cellular respiration. Energy is stored within the chemical bonds within the glucose molecule.
Does glucose make ATP?
Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.
What is the source of cellular energy?
The immediate source of energy for most cells is glucose. But glucose is not the only fuel on which cells depend. Other carbohydrates, fats and proteins may in certain cells or at certain times be used as a source of ATP.
What molecule stores the energy that is produced during cellular respiration quizlet?
ATP stores energy produced by respiration for use by proteins around the cell to do cellular work. Which statement best describes the function of adenosine tri-phosphate (or ATP) in a cell? organic molecules (like sugar).
What is the main energy source for cellular reactions?
ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus. Because of the presence of unstable, high-energy bonds in ATP, it is readily hydrolyzed in reactions to release a large amount of energy.
What is the energy used for in respiration?
This energy is used: to drive the chemical reactions needed to keep organisms alive – the reactions to build complex carbohydrates , proteins and lipids from the products of photosynthesis in plants, and the products of digestion in animals, require energy.
Why do consumers and producers perform cellular respiration?
Both consumers and producers perform cellular respiration to produce the oxygen necessary to sustain life. A. Although they may obtain their sugars in different ways, both consumers and producers rely on cellular respiration to make ATP.
What type of energy is stored in water at the top of a dam?
Choose the term that best describes the type of energy stored in the water at the top of the dam. A. Radiant .
How many molecules are in C. pyruvic acid?
C. two pyruvic acid and two NADH molecules
Which type of cell contains mitochondria and which type of cell contains chloroplasts?
A. Animal cells contain mitochondria and plant cells contain chloroplasts.
What happens when CO2 moves from blood cells to lung cells?
When CO2 moves from your blood cells into your lung cells, it can pass freely across the cell membranes and it is going from a higher concentration to a lower concentration.
What are the components of the cell membrane?
All cell membranes contain phospholipids, proteins, carbohydrates, and cholesterol.
What is the function of oxygen in the metabolism of glucose?
Oxygen provides high-energy electrons for transfer to glucose. Oxygen accepts high- energy electrons after they are stripped from glucose. Oxygen is required to convert ADP to ATP. Oxygen is involved in the initial breakdown of glucose to pyruvic acid.
Is DNA linked to proteins?
D) DNA is not linked to the production of proteins.
Why do consumers and producers perform cellular respiration?
Both consumers and producers perform cellular respiration to produce the oxygen necessary to sustain life. A. Although they may obtain their sugars in different ways, both consumers and producers rely on cellular respiration to make ATP.
What type of energy is stored in water at the top of a dam?
Choose the term that best describes the type of energy stored in the water at the top of the dam. A. Radiant .
