Lesson 7: Video 7.4 ATP

This set of flashcards covers key concepts related to adenosine triphosphate (ATP) and its role in energy transfer within cells.

Adenosine triphosphate (ATP)

A nucleotide that serves as the main energy currency in cells.

Source of chemical potential energy

ATP is the source that provides energy for cellular processes.

Hydrolysis of ATP

The process in which ATP is broken down, releasing energy.

Covalent bonds

Bonds that store energy in the phosphate groups of ATP.

Phosphate group

A functional group containing phosphorus that plays a crucial role in energy transfer.

Exergonic reactions

Reactions that release energy, often used to drive ATP synthesis.

Endergonic processes

Cellular processes that require energy input.

Unstable bond

The bond in ATP hydrolysis that is easily broken to release energy.

Constant synthesis and use of ATP

ATP is continuously produced and consumed in cells, indicating its dynamic role in metabolism.
