ATP/ADP

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells.

Front

What is ADP?

Back

ADP (Adenosine Diphosphate) is a molecule that is formed when ATP loses one phosphate group, releasing energy.

Front

What are the main components of an ATP molecule?

Back

An ATP molecule consists of adenine, ribose sugar, and three phosphate groups.

Front

How is energy released from ATP?

Back

Energy is released when the bond between the second and third phosphate groups is broken.

Front

What role do phosphate bonds play in ATP?

Back

Phosphate bonds store energy; breaking these bonds releases energy for cellular processes.

Front

Where does the energy to regenerate ATP come from?

Back

The energy to regenerate ATP primarily comes from the breakdown of carbohydrates.

Front

What is the significance of ATP in cellular processes?

Back

ATP is often referred to as the energy currency of the cell, powering various biological processes.

Front

How does ADP convert back to ATP?

Back

ADP is converted back to ATP through phosphorylation, typically during cellular respiration.

Front

What is the difference between ATP and ADP?

Back

ATP has three phosphate groups, while ADP has only two, making ATP a higher energy molecule.

Front

What is phosphorylation?

Back

Phosphorylation is the process of adding a phosphate group to a molecule, often converting ADP to ATP.
