6. All of the following substances are produced in a muscle cell under ANAEROBIC conditions EXCEPT: a. ATP b. Pyruvate c. Lactate d. Acetyl CoA e. NADH   7. Folding of the inner membrane forming cristae in mitochondria: a. Allows glucose to enter the organelle and fuel the Kreb cycle. b. Increases the production of CO2, providing carbon to other reactions. c. Breaks ATP into ADP plus phosphate, releasing energy for the Kreb cycle to operate. d. Increases surface area inside the mitochondria, providing space for thousands of copies of the electron transport chain. e.
