Chemical Energy and ATPEnergy is the ability to do work.
Your cells are busy using energy to build new molecules, contract muscles, and carry out active transport.
Without the ability to obtain and use energy, life would cease to exist.

Chemical Energy and ATP
One of the most important compounds that cells use to store and release energy is adenosine triphosphate (ATP).
ATP consists of adenine, a 5-carbon sugar called ribose, and three phosphate groups.
Lesson OverviewLesson Overview Energy and LifeEnergy and Life
Storing Energy
Adenosine diphosphate (ADP) looks almost like ATP, except that it has two phosphate groups instead of three. ADP contains some energy, but not as much as ATP.

Using Biochemical Energy
One way cells use the energy provided by ATP is to carry out active transport.
Lesson OverviewLesson Overview Energy and LifeEnergy and Life
Using Biochemical Energy
ATP powers movement, providing the energy for motor proteins that contract muscle and power the movement of cilia and flagella.
Lesson OverviewLesson Overview Energy and LifeEnergy and Life
Using Biochemical Energy
Energy from ATP powers the synthesis of proteins and responses to chemical signals at the cell surface.
Lesson OverviewLesson Overview Energy and LifeEnergy and Life
Using Biochemical Energy
ATP is not a good molecule for storing large amounts of energy over the long term.
It is more efficient for cells to keep only a small supply of ATP on hand.
Cells can regenerate ATP from ADP as needed by using the energy in foods like glucose.

Heterotrophs and Autotrophs
Organisms that obtain food by consuming other living things are known as heterotrophs.
Lesson OverviewLesson Overview Energy and LifeEnergy and Life
Heterotrophs and AutotrophsOrganisms that make their own food are called autotrophs.
Plants, algae, and some bacteria are able to use light energy from the sun to produce food. The process by which autotrophs use the energy of sunlight to produce high-energy carbohydrates that can be used for food is known as photosynthesis.
