Energy of life
| Term | Definition |
|---|---|
| Photosynthesis | Tranforms solar energy into the chemical energy of a carbon hydrate. |
| Chloroplasts | the organelles that carry on photosynthesis. |
| Stroma | Fluid filled area in a chloroplast. |
| Thylakoids | stacked up green plates, that form grana. |
| Chlorophyll | including pigments reside within the membranes of the thylakoids. They allow pigments are capable of absorbing solar energy, the energy that drives photosynthesis. |
| Reduction | Gain of electrons and H+, and the molecule is said to be reduced, |
| Oxidation | Loss of electrons and H+, the molecule is said to oxidized. |
| Light reactions | the capture solar energy |
| Calvin cycle | synthesis refers to the reaction that produces a carbohydrate. |
| Two types of photosynthetic pigments are? | Chlorophylls and carotenoids. Both absorb visible light. |
| Photosystem (P1) or (PII) | Light reactions. |
| P1 | produces NADPH |
| PII | splits water |
| ATP synthase | the production of ATP captures the realesed energy. |
| NADP+ | is a coenzymes,that accepts e-, becoming NADPH |
| RUBP carboxylase (rubisco) | enzyme |
| C3-Photosynthesis | In a leaf , mesophyll cells, arranged in parallel rows, contain well-formed chloroplasts. Most plants carry C3. |
| C4 | Are plants that are in hot and dry conditions. Are able to avoid the uptake of O2 by rubisco. |
| CAM | stands for crassulaceanacid meetabolism. |
