BIO 110 Study Guide - Midterm Guide: Atp Synthase, Dihydroxyacetone Phosphate, Pyruvate Dehydrogenase Complex
Document Summary
Is done in the mitochondria and the cytoplasm. Interconnected reactions, meaning that if one path is closed, a different route is taken to get the end product.

Regulation: only first step in pathways needs to be regulated, pathways are reversible, flow depends on supply of substrate, the removal of products and activity of enzymes. Feedback inhibition when the product of a reaction prevents further production of that molecule. Allosteric regulation when a molecule binds to a protein somewhere other than it is active site and changes the enzyme shape inhibiting its function. Glucose is converted into 2 pyruvate molecules, 2 atps, 2 nadhs. Has ten steps; five are in the preparative stage and the latter five are in the pay-off phase. Substrate-level phosphorylation the production of atp by transferring a free, inorganic phosphate to adp, making atp.
