photosynthesis
| Question | Answer |
|---|---|
| Photosynthesis has two main stages | light reaction and calvin cycle |
| autotrophs | self feeders, include plants, bacteria, and algea. |
| photosynthesis is a series of endergonic reactions | meaning it makes its own food. |
| oxidation | water molecules are split and lose electrons |
| reduced | electrons are added to it to form glucose |
| stomata | small pores of the outer layer of the cell. |
| photosynthesis takes place in the | chloroplast |
| chloroplast has two membranes | outermembrane and inner membrane called the stroma. sugars are made here |
| thylakoids | are sacs suspended in stroma |
| grana | stacks in thlakoids |
| light reaction | sunslight energy is converted into chemical energy ATP and NADPH that will be used to synthesize glucose. require input of light energy. takes place in the thylakoid membrane |
| calvin cycle | chemical energy from ATP and NADPH is used to produce glucose. DOES NOT REQUIRE LIGHT. carbon fixation happens converts gas CO2 into solid glucose |
| carbon fixation | converts gas C02 into a solid form of glucose. |
| calvin cycle takes place in the | stroma |
