AP Biology: Metabolism and ATP

Front

What is the definition of an endergonic reaction?

Back

An endergonic reaction is a chemical reaction that requires an input of energy to proceed, resulting in a net intake of energy.

Front

What is the definition of an exergonic reaction?

Back

An exergonic reaction is a chemical reaction that releases energy, resulting in a net release of energy.

Front

What is ATP and what does it resemble?

Back

ATP (adenosine triphosphate) is a nucleotide that serves as the primary energy carrier in cells.

Front

What happens to ATP when a phosphate group is removed?

Back

When a phosphate group is removed from ATP, energy is released, and ATP is converted to ADP (adenosine diphosphate).

Front

What is the role of inorganic phosphate in ATP regeneration?

Back

Inorganic phosphate produced in the cytosol combines with ADP to regenerate ATP.

Front

What is the significance of ATP in metabolism?

Back

ATP is crucial for metabolism as it provides the energy needed for various cellular processes.

Front

What is the difference between ATP and ADP?

Back

ATP has three phosphate groups, while ADP has two. ATP can release energy by losing a phosphate group to become ADP.

Front

What is the energy currency of the cell?

Back

ATP (adenosine triphosphate) is known as the energy currency of the cell.

Front

What type of reaction is cellular respiration considered?

Back

Cellular respiration is considered an exergonic reaction because it releases energy.

Front

What is the relationship between ATP and energy coupling?

Back

ATP is used in energy coupling to transfer energy from exergonic reactions to drive endergonic reactions.
