Cellular Energy

1. A saclike photosynthetic membrane found inside chloroplasts.
7. A metabolic process that requires oxygen to occur.
9. Cycle The light-independent reactions of photosynthesis that use ATP and NADPH to build high-energy sugars.
10. Small openings on the underside of leaves that allow gas exchange.
11. The organelle in plant and algae cells where photosynthesis occurs.
14. Cycle The second stage of cellular respiration that produces carbon dioxide and electron carriers.
16. The process plants use to convert light energy into chemical energy stored in glucose.
17. A lower-energy molecule that can be recharged into ATP by adding a phosphate group.
18. The simple sugar molecule produced during photosynthesis and broken down in respiration.

2. A metabolic process that does not require oxygen.
3. An anaerobic process that allows cells to keep making small amounts of ATP without oxygen.
4. The organelle where the final stages of aerobic cellular respiration take place.
5. The first step of cellular respiration where glucose is split in half in the cytoplasm.
6. Acid A waste product produced by fermentation in animal muscle cells during intense exercise
8. Respiration The process that releases energy from food molecules in the presence of oxygen
10. The fluid-filled space surrounding the thylakoids inside a chloroplast.
12. An electron carrier molecule that transfers high-energy electrons during photosynthesis.
13. The green pigment inside chloroplasts that absorbs light energy.
15. The main energy-storing molecule used by all living cells.
