In cellular respiration, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials. Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules to support growth or to release energy.
How is food changed through chemical reactions?
Develop a model to describe how food is changed through chemical reactions to form new molecules that support growth and/or release energy as matter cycles through an organism. Emphasis is on describing that during cellular respiration molecules are broken apart and rearranged into new molecules and that this process releases energy. (PS3.D, LS1.C)

The food provides both energy and the building blocks to create new cells and repair the body. Learn about how we break down molecules into energy in this process.
How is food broken down into energy?
Large cells in our food are broken down by the digestive system, and converted into energy through cellular respiration. The food provides both energy and the building blocks to create new cells and repair the body. Learn about how we break down molecules into energy in this process. We eat food every day of our lives.
How do we get energy and building blocks from food?
We get both energy and those building blocks from food. Digestion is the process where the large molecules in the food that we eat are broken down into smaller ones that we can use for energy or as building blocks. This is done in the digestive system by enzymes found in saliva, in stomach acid, in the small intestine, and in the large intestine.

How do molecules release energy?
Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation.
How do cells use molecules to release energy for your body to run?
Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP (Figure below). ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street.
How do animals release energy needed for growth and repair?
By breaking the chemical bonds in glucose, cells release the stored energy and make the ATP they need. The process in which glucose is broken down and ATP is made is called cellular respiration .
What provides the energy for growth?
In fact, the Sun is the ultimate source of energy for almost all cells, because photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction (Figure 1).
What process happens in cells to release energy?
The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP. Some of the energy released is lost as heat.
What molecules help cells store and release energy?
ATPAdenosine 5'-triphosphate, or ATP, is the principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank.
What process do animals use to release energy?
cellular respirationThe cells all rely on the same process to get their energy: cellular respiration, a process that releases energy by combining glucose and oxygen. We can explain cellular respiration—and how animals get energy to move—by answering the four numbered questions on the Three Questions handout: 1.
How do animals release their energy?
In eukaryotic cells, cellular respiration takes place mostly in the mitochondria. During cellular respiration, food (such as glucose) is broken down into CO2 and H2O, and energy is liberated, or freed. In animals, most of the freed energy is used to keep a constant body temperature.
What causes animals to grow and make energy?
Animal growth is determined by a complex variety of factors but these can be reduced to three main categories: the animal's gene pool, the nutrients with which it is supplied, and its environment. The common factor linking and communicating these is the endocrine system.
What creates energy for growth and reproduction in plants?
During photosynthesis, carbon dioxide, a gas, is combined with water and solar energy, and converted to carbohydrates, a solid. Formation of carbohydrates is a chemical way to store the sun's energy as “food.” Carbohydrates produced from photosynthesis provide energy for all plant growth and maintenance.
What energy system is used in running?
The aerobic systemThe aerobic system is the predominant energy system used for races lasting longer than three minutes. Since distance running is primarily limited by the delivery and use of oxygen, most of your training should focus on improving your aerobic system's ability to supply oxygen to your running muscles.
What energy is released when running?
Energy cannot be created or destroyed, but it can go elsewhere. As the person runs, most of their stored energy is released in the form of thermal energy. This is why people get hot and start to sweat when they do physical activity such as running.
What cells make your body run?
What are cells? Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life. Cells house the biological machinery that makes the proteins, chemicals, and signals responsible for everything that happens inside our bodies.
What energy are you using when running?
When we go for a run we are using chemical energy in our bodies to produce movement (kinetic energy), which in turn converts to warmth (thermal energy). Cycling downhill involves kinetic and gravitational energy.
How do her cells use these molecules to release energy for her body to ...
In cells use oxygen to release energy stored in sugars such as glucose. In fact, most of the energy used by the cells in your body is provided by cellular respiration.
What is the process of cellular respiration?
In these processes, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials.
How does food move through the body?
Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules, to support growth, or to release energy.
What is the concept of food as fuel?
In addition, this unit introduces the concept of food as fuel and lays the groundwork for future units in which students figure out that both food and other sources of fuels are sources of matter and sources of energy, drawing connections between chemical reactions that transfer and convert energy in living and nonliving systems. This connects to the idea identified on page 196 of Framework for K–12 Science Education (National Research Council, 2012): “By middle school, a more precise idea of energy—for example, the understanding that food or fuel undergoes a chemical reaction with oxygen that releases stored energy—can emerge.”
How is the growth of an animal controlled?
The growth of an animal is controlled by genetic factors, * food intake, and interactions with other organisms, and each species has a typical adult size range.
Does the cell unit introduce cells to students?
This unit does not introduce cells to students. It uses that prerequisite knowledge to build understanding that the organization of the body goes from cells, to tissues, to organs, to subsystems to multiple subsystems working together in one body system.
Do we have chemical reactions?
Some molecules, like fiber, stay the same throughout digestion and, therefore, do not undergo chemical reactions.

Cellular respiration equation. This reaction releases energy, which leads to the creation of ATP, which in turn allows cells to do their jobs. Lesson Summary. Everything our bodies do, from movement, to the thought process in our brains, to growth and repair, happens due to the energy and material from the food that we eat.
Where does energy come from in the digestive process?
The energy that we get from this digestive process comes from the bonds that are broken inside each molecule - breaking bonds releases energy. These broken down molecules are then passed into the blood and move to the part of the body where they are needed. Here are some details about enzymes involved in digestion:
