Unit 3 Practice Questions

Front

What is ATP?

Back

ATP stands for Adenosine triphosphate, a molecule that stores and transfers energy within cells.

Front

How does ATP store energy?

Back

ATP stores energy in the bonds between its three phosphate groups.

Front

What happens when ATP is converted to ADP?

Back

When ATP is converted to ADP (adenosine diphosphate), energy is released for cellular processes.

Front

What is the process of converting ADP back to ATP called?

Back

The process of converting ADP back to ATP is called phosphorylation.

Front

What are the main phases of mitosis?

Back

The main phases of mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What is cellular respiration?

Back

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

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the role of ATP in cellular processes?

Back

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

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the significance of the phosphate groups in ATP?

Back

The phosphate groups in ATP are high-energy bonds; breaking these bonds releases energy for cellular work.
