1st attempt How do fermentation reactions in oxygen-starved muscle cells and anaerobically grown yeast cells differ? Choose one: Fermentation in muscle cells regenerates NAD and in yeast regenerates glucose. Fermentation in muscle cells generates NAD and in yeast generates NADH. Fermentation in muscle cells produces lactate and in yeast produces ethanol plus CO2. Fermentation in muscle cells produces ethanol plus CO2 and in yeast produces lactate. Fermentation in yeast cells includes glycolysis, whereas in muscle cells it bypasses glycolysis.

Question 9 12 pts In glycolysis, glucose is converted to [Select] in 10 enzymatic Toalet reactions resulting in the net synthesis of [Select] moles of ATP per mole of glucose. During fermentation, the end products of glucose metabolism are [Select] and the electron acceptors are [Select] In aerobic metabolism, the terminal acceptor of electrons from glucose Select] Most of the energy arising from aerobic respiration is generated in the [Select] phase.
