BIOL 1000 Chapter Notes - Chapter 2: Atp Synthase, Cellular Respiration, Intermembrane Space
Document Summary
Cellular respiration, steps of cellular respiration, glycolysis, pyruvate oxidation, krebs cycle or citric acid cycle, electron transport chain, chemiosmosis. Split glucose (a 6-carbon molecule) into two 3-carbon molecules: produce atp net of 2 atp molecules for 1 molecule of glucose. Starts in cytosol: produce acetyl-coa important. If oxygen: pyruvates go into mitochondrial matrix to undergo pyruvate oxidation. If no oxygen: fermentation in cytosol (ethanol or lactate) In mitochondrial matrix: transfer energy, originally from glucose, into other molecules, complete the oxidation of glucose, generates a bit of atp, generates a lot of electron carriers. In inner mitochondrial: create and maintain the proton membrane concentration gradient that will be. Transfer protons to the used to fuel atp production intermembrane space: transfer protons from the matrix to the intermembrane space (across the inner membrane, 4 complexes of various proteins, not including atp synthase. In the matrix (atp produced: proton concentration gradient (high.
