Cellular Energy Vocabulary

Front

What are hydrogen carriers?

Back

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

Front

What does the law of conservation of energy state?

Back

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

Front

What is an endergonic reaction?

Back

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

Front

What characterizes anabolic reactions?

Back

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

Front

What characterizes catabolic reactions?

Back

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

Front

What is ATP?

Back

Adenosine triphosphate, the primary energy carrier in cells.

Front

What is the process of converting ADP and P back into ATP called?

Back

Phosphorylation, which is an anabolic and endergonic process.

Front

What is the process of breaking down ATP to form ADP and P called?

Back

Hydrolysis, which is a catabolic and exergonic process.

Front

What is the role of ATP in cellular energy?

Back

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

Front

What is the difference between exergonic and endergonic reactions?

Back

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