Unit 3 Study Guide: Energy Flow 24-25

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells. It consists of adenine, ribose, and three phosphate groups.

Front

What is the primary function of ATP in cells?

Back

The primary function of ATP is to store and transfer energy for various cellular processes.

Front

Which bond in ATP is easiest to break to release energy?

Back

The bond between the second and third phosphate groups.

Front

What happens when ATP is converted to ADP?

Back

When ATP is converted to ADP (Adenosine Diphosphate), it releases energy that can be used for cellular work.

Front

What is ADP?

Back

ADP (Adenosine Diphosphate) is a molecule that is formed when ATP loses one phosphate group, resulting in a release of energy.

Front

How is ATP regenerated from ADP?

Back

ATP is regenerated from ADP through the addition of a phosphate group, typically during cellular respiration or photosynthesis.

Front

What is cellular respiration?

Back

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

Front

What role does photosynthesis play in ATP production?

Back

Photosynthesis converts light energy into chemical energy, producing glucose that can be used to generate ATP.

Front

What is the relationship between ATP and energy?

Back

ATP serves as the primary energy currency of the cell, providing energy for biochemical reactions.

Front

What is the difference between ADP and ATP in terms of energy storage?

Back

ATP has three phosphate groups and stores more energy than ADP, which has only two phosphate groups.
