Please explain why as well. Thank you!

8. The number of acetyl-CoA molecules produced from one molecule of glucose is

A. one

B. two

C. three

D. four

E. zero, since acetyl-CoA is only formed during oxidation of fatty acids

10. Which of the following statements about the TCA cycle and mitochondria is

CORRECT?

A. The TCA cycle takes place in the intermembrane space

B. The outer membrane of the mitochondrion is extensively folded to form structures

called cristae

C. The inner membrane is much more permeable to small molecules versus the outer

membrane

D. Pyruvate from glycolysis is generated/produced in the mitochondrial matrix

E. None of the above

Answer #1

8. Two acetyl coA molecules are produced from one glucose. If you recall, one glucose molecule is broken down into two pyruvate molecules at the end of glycolysis. Each pyruvate is decarboxylated to produce acetyl coA. Thus one glucose produces two acetyl coA molecules

10.none of the above..

TCA takes place in the proteins embedded in the inner membrane

Inner membrane is extensively folded into cristae

Outer membrane is more permeable has porins

Pyruvate from.glycolysis is generated in cytoplasm

ii. During the transfer of acetyl CoA from the mitochondrion to the cytosol, malate will be generated in the cytosol. Although malate can be brought back into the mitochondrion directly, it will instead be converted into pyruvate which then enters the mitochondrion. Why does this happen? 1 point a. The conversion of malate into pyruvate generates NADPH which can be used in fatty acid synthesis. b. Movement of malate into the mitochondrion requires a lot of energy. c. In the...
