Metabolism, Anabolism, and Catabolism

Define anabolism

Anabolism is the building of molecules with the use of energy

Describe an example of metabolism

Cells need energy to function. If a person is eating something that has sugar, the sugar molecules get broken down into simpler molecules and that releases energy. That energy is then used to build up molecules in the body

Describe how enzymes work

Chemicals used in the chemical reaction bind to the enzyme. This binding process changes the shape of the chemicals and allows them to bind and create a chemical reaction

Define catabolism

The breakdown of molecules

Describe an example of anabolism

When two amino acids are added together and energy is used, it creates a molecule known as a protein

Write a chemical equation resulting in the production of ATP

ADP + P = ATP adenosine diphosphate + phosphate = adenosine triphosphate

Write a chemical equation with ADP as a product

ATP = ADP + P + ENERGY adenosine triophosphate is broken down into adenosine diphosphate, phosphate, and energy

What is ATP?

ATP stands for adenosine triphosphate and is energy that is released from the breakdown of foods.

Give an example of a chemical process using an enzyme

Anabolic processes in the body make enzymes

What is the purpose of enzymes?

Enzymes act like catalysts and speed up chemical reactions in the body

Describe and give an example of catabolism

Glucose gets broken down in the cell to provide energy, or ATP, water, and carbon dioxide

Define metabolism

Metabolism refers to the chemical reactions in the body that build and breakdown molecules
