Document Summary

Definitions: energy - capacity to do work, work - force acting on an object over a distance, change - rearranging a collection of matter. Redox reactions: oxidation vs reduction, electrons from low to high electronegativity = - g, organic redox, oxidation states of c atoms (c=o is most oxidized because o has a higher electronegativity, gibbs free energy of carbohydrates vs triacylglycerols. Energy coupling: exergonic reactions are used to power endergonic reactions, phosphorylated intermediate. Structure - 3 phosphates, ribose, adenosine: uses energy coupling, atp adp (cid:396)eleases (cid:1011). (cid:1007) k(cid:272)al/(cid:373)ole. Synthesis and breakdown: substrate-level phosphorylation (uses kinase, chemiosmosis (atp synthase, hydrolysis, uses of atp, movement, endergonic chemical reactions, active transport. Nadph: cyclic electron flow, only uses ps i, produces atp. Stroma: uses atp and nadph, anabolic, endergonic, produces g3p, carbon fixation, 3 co2 + (cid:1007) (cid:396)i(cid:271)ulose (cid:271)isphosphate (cid:894)usi(cid:374)g (cid:396)u(cid:271)is(cid:272)o e(cid:374)z(cid:455)(cid:373)e(cid:895) (cid:1010) (cid:1007)- phosphoglycerate (3 c, 1 p)
