Chapter 8: Photosynthesis and cell respiration
| Question | Answer |
|---|---|
| energy | ability to do work |
| ATP | quick source of energy energy stored/ phosphate gained (adenine, ribose, and 3 phosphates |
| ADP | energy released and remove a phosphate |
| chlorophyll | green pigment found in plants |
| NADPH | electron carrier (filled with electrons) |
| NADP+ | another energy carrier |
| ETC | electron transport chain (series of proteins) |
| photolysis | to replace chlorophyll's lost electrons water is split by an enzyme releasing oxygen, 4 e-, and 4 H+ |
| ATP synthase | as electron move in the light-dependent reaction, H+ ions are pumped across the membrane and later flow back through this protein that makes ATP |
| Glucose | simple sugar |
| Glycolysis | anaerobic process-no energy required takes place in cytoplasm of cell glucose is broken in half to form 2 pyruvate when broken 2 ATP are needed but 4 are produce, gain of 4 ATP |
| Pyruvate | a three carbon molecule that is a product og glycolysis |
| aerobic | oxygen required |
| anaerobic | no oxygen required |
| fermation | if there is no oxygen available to cells following glycolysis, cells can produce a small amount of ATP until oxygen is available again (two types: lactic acid and alcoholic) |
