Document Summary
Acetaldehyde is normally degraded by enzyme acetaldehyde: competitive inhibitor: substrate can not bind. Increase the concentration of the inhibitor = shut it down. As acetaldehyde starts to build up, you feel really sick, don"t want to drink. If the patient stops taking the drug, they fell fine and can drink more. Calvin cycle: stroma (run cycle 6 times to get 1 molecule of glucose) Need: carbon dioxide, atp, nadph: oxidation of water, with o2 produced as a byproduct = light dependent reaction: h2o o2, rubisco binds to the carbon dioxide o, reduction of co2 to form carbohydrates: independent of light: Pga: atp adp (+) nadph nadp+ +h} specific to plants and photosynthesis, can control it because it is a different form. Use water as source of electrons, use them to evoke a gradient. Protons go through atp synthase to make atp: photosystem i: gets electrons from photosystem i.
