Question

It would oxidize the substrate and phosphorylate it without releasing it. It would oxidize the substrate but not release it. It would phosphorylate the substrate on the 2 position instead of the 1 position. It would behave just like the normal enzyme. In the absence of oxygen, yeast cells can switch to a completely anaerobic metabolism called fermentation. Which of the following is a final product of fermentation in yeast? Pyruvate must move from the cytosol into the mitochondria, where it oxidized to form CO_2 and acetyl CoA by the pyruvate dehydrogenase complex. How many different enzymes and what total number of polypeptides, respectively, are required to perform this oxidation process in the mitochondrion? 1; 60 3; 3 3; 26 3; 60 In the absence of oxygen, mammalian cells will endure for a short time using a process called fermentation. Which of the following is a final product of fermentation in mammalian cells?

Explanation / Answer

1. D is the answer as it is puruvate(CH3COCOO-) which is intermediary compound. It id converted to ethanol.

2. the oxidation of pyruvate required enzyme Complex called pyruvate dehydrogenase which consists of three enzymes including over 60 subunits. D is answer.

3.A is answer. Lactate is produced during intense exercise when there is limited o2 supply.
