It would oxidize the substrate and phosphorylate it without

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?

Solution

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.
