BC 351 Lecture Notes - Lipoic Acid, Fumaric Acid, Isocitric Acid
Document Summary
Cellular respiration is the molecular process by which cells consume o2 and produce co2 and h2o. Tca cycle pyruvate 6co2, atp, nadh, fadh2. Electrons removed in the process, put on electron carriers. All reactions in citric acid cycle must be run twice for each glucose molecule. Enzyme complex contains 3 enzymes: e1, e2, and e3. The complex contains 24 of e1, 24 of e2, and 12 of e3. Vitamin derivation of nad+ - niacin, fad riboflavin, tpp thiamine, coa panthoic acid. Start with acetyl-coa and oxaloacetate, end with oxaloacetate. [oaa] is very likely low due to the exergonic nature of the reaction. H2o added to reach intermediate, then taken away to reach product. This energy is derived from the redox reaction. Fad fadh2 usually occurs with alkane alkene. Nad+ nadh usually occurs with alcohol ketone/aldehyde. Oh- added to fumarate, h+ added at transition. Product concentration is very low, enabling the reaction to occur.
