Question

unit 3 test.m
3.1.9-12.g which statement best explains the role of atp in cellular respiration?
atp stores energy released when glucose bonds are broken and provides energy for cellular processes.
atp captures sunlight energy and converts it directly into glucose.
atp is used only in plant cells to transport oxygen to mitochondria.

Explanation:

1. Analyze the first option: In cellular respiration, glucose is broken down, and the energy released is used to synthesize ATP. ATP then stores this energy and provides it for various cellular processes. This matches the role of ATP.
2. Analyze the second option: Capturing sunlight energy and converting it to glucose is the role of photosynthesis (specifically chlorophyll and related processes), not ATP. So this is incorrect.
3. Analyze the third option: ATP is used in both plant and animal cells, and it is not involved in transporting oxygen to mitochondria. Oxygen transport is related to hemoglobin in blood (in animals) or other mechanisms, and ATP's role is energy transfer, not oxygen transport. So this is incorrect.

Answer:

ATP stores energy released when glucose bonds are broken and provides energy for cellular processes.
