Biology 1202B Lecture Notes - Lecture 9: Chlorophyll, Sucrose, Cellulose
Document Summary
Pq takes away from the stroma and adds to the lumen. Nadp+ reductase takes hydrogen from the stroma, increases electrical potential gradient. Adp:atp ratio is high: adp is high, atp is low. Calvin cycle: purpose is to make g3p, rubisco has a binding site for co2 and also has a binding site for rubp. Rubisco is not an efficient enzyme, one of the slowest enzyme. Rubisco fixes co2 and produces 3 phosophoglycerates: g3p. Produce 2 g3p for each turn of the calvin cycle. You need 5 carbons to regenerate of rubp. Every time the cycle goes, it has 1 net carbon, so needs to go 3 times in order to have enough carbon that can be used to make g3p and convert its to glucose. Reduction: reducing molecules by adding electrons from nadph, nadph is being oxidized in order to reduce. Starting point for synthesis of: sucrose, starches, cellulose, amino acids, fatty acids and lipids, proteins, nucleic acid.
