ATP-ADP Cycle

Front

What is the ATP-ADP cycle?

Back

The ATP-ADP cycle is a process in which adenosine triphosphate (ATP) is converted to adenosine diphosphate (ADP) and a phosphate group, releasing energy for cellular activities. ADP can then be converted back to ATP through cellular respiration.

Front

What does ATP stand for?

Back

ATP stands for adenosine triphosphate.

Front

What does ADP stand for?

Back

ADP stands for adenosine diphosphate.

Front

What is the primary function of ATP in cells?

Back

The primary function of ATP is to store and transfer energy within cells for various biochemical processes.

Front

How is ATP produced in cells?

Back

ATP is produced in cells through processes such as cellular respiration and photosynthesis.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs sunlight, which is essential for the process of photosynthesis.

Front

What are the main products of the ATP-ADP cycle?

Back

The main products of the ATP-ADP cycle are ATP (energy) and ADP (used for recycling back into ATP).

Front

What is the significance of the phosphate group in ATP?

Back

The phosphate group in ATP is crucial because its removal (hydrolysis) releases energy that powers cellular processes.

Front

What is the equation for the conversion of ATP to ADP?

Back

ATP → ADP + Pi + energy (where Pi is inorganic phosphate).

Front

What is the relationship between photosynthesis and the ATP-ADP cycle?

Back

Photosynthesis produces ATP through the light-dependent reactions, which is then used in the ATP-ADP cycle to provide energy for cellular activities.
