Textbook QuestionWhich of the following correctly describe the fermentation pathway? Select True or False for each statement. T/F It includes a reaction that oxidizes NADH to NAD+. T/F It synthesizes ATP by substrate-level phosphorylation. T/F It includes a reaction that reduces NAD+ to NADH. T/F It synthesizes electron acceptors, so that cellular respiration can continue.1015views
