October 17, 2011 Biology 311C Lecture 22 Look at powerpoints on Blackboard. Substrate level phosphorylation is when the enzyme translated the substrate to STP. The citric acid cycle is a series of enzyme-catalysed chemical reactions, which is of central importance in all living cells, especially those that use oxygen as part of cellular respiration. In eukaryotic cells, the citric acid cycle occurs in the matrix of the mitochondrion. What goes in is acetal coenzyme A, oxaloacetate, citrate, isocitrate, alpha ketoglutarate, succinyl CoA, succinate, fumarate, and malate. What goes out is NADH, ATP, FADH 2 . The enzyme for KC step 1 is inhibited by high concentrations of NADH The KC indirectly uses oxygen, the oxygen changes NADH to NAD+ and those will go to KC to keep it going. The pathway of electron transport: Chain’s components are multiprotein complexes such as prosthetic groups.
