Cell Energy

3. Light-absorbing colored molecules found in the thylakoid membranes of chloroplast.
6. Flattened, saclike membranes that are arranged in stacks.
7. The catabolic pathway in which organic molecules are broken down to release energy for use by a cell.
8. Includes the Krebs cycle and electron transport and is an aerobic process.
10. require oxygen.
11. The ability to do work.
14. The most important biological molecule that provides chemical energy. ATP
15. The process by which glucose is broken down in the cytoplasm.
16. The fluid-filled space that is outside the grana.

1. The study of the flow and transformation of energy in the universe.
2. The series of reactions in which pyruvate is broken down into carbon dioxide also known as the tricarboxylic acid cycle or citric acid cycle.
4. The anabolic pathway in which light energy from the sun is converted to chemical energy for use by the cell.
5. The second phase of photosynthesis in which energy is stored in organic molecules such as glucose.
8. Do not require oxygen.
9. Occurs in the cytoplasm and regenerates the cells supply of NAD+ while producing a small amount of ATP.
12. All of the chemical reactions in a cell.
13. Stacks of thylakoids.
