ADP vs ATP

Front

What is ATP?

Back

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

Front

What is ADP?

Back

ADP (Adenosine Diphosphate) is a molecule that is formed when ATP loses one phosphate group. It consists of adenine, ribose sugar, and two phosphate groups.

Front

How do ATP and ADP differ in terms of phosphate groups?

Back

ATP has three phosphate groups, while ADP has two phosphate groups.

Front

What role do mitochondria play in cellular energy production?

Back

Mitochondria are known as the powerhouse of the cell, as they produce ATP through cellular respiration.

Front

Where is energy stored in ATP molecules?

Back

Energy is stored in the high-energy phosphate bonds between the phosphate groups.

Front

What happens to ATP when it is used for energy?

Back

When ATP is used for energy, it loses one phosphate group and is converted to ADP.

Front

Why is ADP compared to a battery in need of recharging?

Back

ADP is like a battery in need of recharging because it can be converted back to ATP by adding a phosphate group, thus storing energy again.

Front

What is the significance of the ribose sugar in ATP and ADP?

Back

Ribose sugar is a crucial component of both ATP and ADP, providing the structural framework for the molecule.

Front

What is the function of the adenine group in ATP?

Back

The adenine group is part of the ATP structure and is involved in the energy transfer process.

Front

How do cells regenerate ATP from ADP?

Back

Cells regenerate ATP from ADP through a process called phosphorylation, where a phosphate group is added back to ADP.
