Cellular Energy Vocabulary

Molecules that transport hydrogen atoms in biological processes, including NADH and FADH2.

Energy cannot be created or destroyed, only transformed from one form to another.

A type of reaction that requires energy input to proceed, resulting in products with higher energy than the reactants.

Reactions that build larger molecules from smaller ones, often requiring energy input.

Reactions that break down larger molecules into smaller ones, releasing energy.

Adenosine triphosphate, the primary energy carrier in cells.

Phosphorylation, which is an anabolic and endergonic process.

Hydrolysis, which is a catabolic and exergonic process.

ATP serves as a direct energy source for various cellular processes.

Exergonic reactions release energy, while endergonic reactions require energy input.
