BIOL 201 Lecture Notes - Lecture 28: Atp Hydrolysis, Oxidative Phosphorylation, Citric Acid Cycle
Document Summary
Ps7 q6: b, c, a, a (3 protons) G" = -45 kj/mol under cellular conditions @ 25 c. Recall: phosphate is a good lg, phosphorylation can help drive reactions. Understand the purpose of each reaction, so that you can see what is happening in each step. Anabolism refers to all metabolic reactions that are atp and nadh-utilizing; atp and. Catabolism refers to all metabolic reactions that are atp and nadh-synthesizing; atp and. Atp is made during catabolism, and used to drive biosynthetic work (anabolism). Glycolysis and the krebs cycle are done via substrate level phosphorylation . Three mechanisms for atp synthesis in nature: oxidative phosphorylation (plants, animals, bacteria) et part ii, photophosphorylation (plants, bacteria) et part ii, substrate-level phosphorylation (aka slp, plants, animals, bacteria) metabolism part i. Substrate-level phosphorylation (slp) : a multi-step process that uses a different enzyme for each step of the reaction pathway (direct transfer of a phosphoryl group to adp from another phosphorylated compound)
