AP Biology: Metabolism and ATP

Front

What is the main cellular energy molecule?

Back

ATP (Adenosine Triphosphate) is the main cellular energy molecule that powers various biological processes.

Front

Organisms get their energy to do work from ___________ energy.

Back

Chemical energy is the form of energy that organisms use to perform work.

Front

What is feedback inhibition?

Back

Feedback inhibition is a regulatory mechanism where the end product of a metabolic pathway inhibits an earlier step in the pathway.

Front

Where is energy stored in ATP?

Back

Energy is stored in the bonds between the phosphate groups in ATP.

Front

Why is ATP called a cell’s 'energy currency'?

Back

ATP is called a cell’s 'energy currency' because it supplies most of the energy that drives metabolism.

Front

What is the role of ATP in metabolism?

Back

ATP serves as a primary energy carrier in cells, facilitating various metabolic reactions.

Front

Define metabolism.

Back

Metabolism is the sum of all chemical reactions that occur within a living organism to maintain life.

Front

What is the difference between catabolism and anabolism?

Back

Catabolism is the breakdown of molecules to obtain energy, while anabolism is the synthesis of complex molecules from simpler ones.

Front

What is the significance of the phosphate groups in ATP?

Back

The phosphate groups in ATP are high-energy bonds that release energy when broken, powering cellular processes.

Front

What is the process of cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.
