    What is ATP?

    Functions as the energy currency in cells.

    What processes require energy supplied by ATP?

    Active transport, macromolecule synthesis, and cell movement.

    How is energy released from ATP?

    Through hydrolysis to ADP and phosphate.

    What is the role of glucose in cellular respiration?

    Serves as a primary substrate for ATP production.

    What distinguishes aerobic from anaerobic respiration?

    Aerobic requires oxygen; anaerobic does not.

    What is the yield of ATP in anaerobic respiration?

    Relatively small compared to aerobic respiration.

    What happens during glycolysis?

    Glucose is broken down into pyruvate, yielding ATP.

    What is the consequence of anaerobic respiration in humans?

    Produces lactic acid and a small amount of ATP.

    How does temperature affect the rate of cellular respiration?

    Higher temperatures generally increase respiration rates.

    What is the function of a respirometer?

    Measures the rate of respiration by tracking oxygen consumption.

    What is the significance of ATP's solubility?

    Allows it to move easily in aqueous environments.

    What is produced as a waste product in aerobic respiration?

    Carbon dioxide and water.

    What is the main difference in location for aerobic and anaerobic respiration?

    Aerobic occurs in mitochondria; anaerobic occurs in the cytoplasm.

    What happens if oxygen is not available during respiration?

    Anaerobic respiration occurs, producing less ATP.

    What is the role of enzymes in ATP interconversion?

    Facilitate the phosphorylation and hydrolysis processes.
