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 results when ATP loses one phosphate group, and it can be converted back to ATP.

Front

How does ATP release energy?

Back

ATP releases energy when the bond between the 2nd and 3rd phosphate groups is broken, resulting in ADP and a free phosphate.

Front

What is the role of ATP in cellular processes?

Back

ATP provides energy for various cellular processes, including muscle contraction, nerve impulse propagation, and biosynthesis.

Front

What are the components of an ATP molecule?

Back

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

Front

What happens to ADP during cellular respiration?

Back

During cellular respiration, ADP can be converted back to ATP by adding a phosphate group.

Front

Why is ATP often referred to as the energy currency of the cell?

Back

ATP is called the energy currency of the cell because it is used to transfer energy for various cellular activities.

Front

What is the significance of the phosphate groups in ATP?

Back

The phosphate groups in ATP store potential energy, which is released when they are broken off.

Front

How can ADP be compared to a battery?

Back

ADP can be compared to a battery in need of recharging because it can be converted back to ATP, which is fully charged.

Front

What is the process of phosphorylation?

Back

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