6. Which of the four stages of respiration does NOT take place in mitochondria A. pyruvate processing B. glycolysis C. Citric acid cycle D. electron transport and oxidative phosphorylation 7. The citric acid cycle is a set of sequential reactions where 2 carbon atoms from Acetyl CoA (that derives from a glucose molecule) are coupled to a 4 carbon molecule. The carbon atoms from Acetyl CoA are released as CO2. Redox reactions and phosphorylation reactions are used to harvest energy...

ii. During the transfer of acetyl CoA from the mitochondrion to the cytosol, malate will be generated in the cytosol. Although malate can be brought back into the mitochondrion directly, it will instead be converted into pyruvate which then enters the mitochondrion. Why does this happen? 1 point a. The conversion of malate into pyruvate generates NADPH which can be used in fatty acid synthesis. b. Movement of malate into the mitochondrion requires a lot of energy. c. In the...
