| # | Answer | Explanation |
|---|---|---|
| 1 | B. ATP | ATP (adenosine triphosphate) is the main molecule cells use to store and transfer usable energy. |
| 2 | Plants obtain energy from sunlight through photosynthesis. | Plants capture light energy and convert it into chemical energy during photosynthesis. |
| 3 | energy | Cellular respiration releases usable energy from glucose, which cells transfer into ATP. |
| 4 | Photosynthesis stores energy by making glucose, while cellular respiration releases energy by breaking down glucose. | The two processes are closely connected and have opposite overall roles in energy transfer. |
| 5 | Cellular respiration helps supply ATP because it breaks down glucose to release energy that cells can use. | During exercise, cells increase cellular respiration to meet the higher demand for ATP. |
