BIOL 201 Lecture Notes - Lecture 34: Atp Synthase, Light-Independent Reactions, Photophosphorylation
Document Summary
Production of 3c sugars from the calvin cycle: Energy capture via etc & atp production (covered in unit 4b) Unique features of rubisco and how the calvin cycle shuffles carbons around. Universal metabolic pathways : use stored energy to make atp: acetyl-coa production (glycolysis and conversion of pyruvate, acetyl-coa oxidation (tca cycle) produces atp and heis, etc and oxidative phosphorylation. Autotrophic reactions : make stored energy (from co 2 and light) Light depend reactions (h 2 o o 2 , produces nadph and atp) Carbon-assimilation reactions (consumes atp to make triose phosphates - g3p) The atp generated in photosynthesis is not directly used to drive reactions needed for plant growth and development atp doesn"t leave the chloroplast since there is no atp transporter. Photophosphorylation in chloroplasts is similar to atp generation in mitochondria in the way that: The thylakoid membrane (containing the electron carriers and atp-forming enzymes) is similar to the inner mitochondrial membrane.
