CHEM 352 Lecture Notes - Lecture 13: Hexose, Ribulose, Photorespiration
Document Summary
Reductase: ferredoxin can only carry one electron, while nadph carries 2, ferredoxin-nadp+ reductase catalyzes the reduction of. Nadp+ to nadph by ferredoxin: the uptake of protons by ferredoxin-nadp+ reductase contributes to the proton gradient, the flow of electrons from h2o to nadp+ looks like the letter. Z: be able to draw the z scheme on the test. Atp to be generated without forming nadph or o2: stoichiometry of the light reactions, in ps ii, four photons are absorbed, o2 is generated and. 4 h+ molecules are released into the thylakoid lumen: two molecules of plastoquinol are oxized and release 8. Atp: if the cyclic photophosphorylation pathway is used, 2 photons must be absorbed to yield 1 atp molecule, only uses ps i. Chapter 20: the calvin cycle: the light reactions, light energy was transformed into atp and biosynthetic reducing power, the dark reactions, use atp and nadph from the light reactions to reduce.
