Bio Unit 3 - Concept 2 - ATP

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 is the role of phosphate in the ATP-ADP cycle?

Back

Phosphate groups are added to ADP to regenerate ATP, allowing energy storage.

Front

What does the term 'endothermic' mean in the context of the reaction ADP → ATP + P?

Back

Endothermic refers to a reaction that absorbs energy from its surroundings.

Front

What is the significance of the ribose sugar in ATP?

Back

Ribose is a sugar that forms part of the ATP structure, connecting adenine and phosphate groups.

Front

What is the process of cellular respiration?

Back

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

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions release energy, while endothermic reactions absorb energy.

Front

How is energy released from ATP?

Back

Energy is released when ATP is converted to ADP and a phosphate group, breaking the bond between the last two phosphates.

Front

What is the primary function of ATP in cells?

Back

ATP serves as the main energy currency of the cell, powering various cellular processes.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose, which can be used to form ATP.
