True or False
Cytoplasmic NADH cannot cross into the mitochondrial membrane and must use shuttle systems in order to pass H+ to mitochondria.
Homework Answers
It is true . NADH-H+ is continuously formed in the cytoplasm by glycolysis and it must be oxidized to regenerate cytoplasmic NAD+ which is important for the process of glycolysis to proceed normally.
The mitochondrial shuttles are systems used to transport reducing agents across the inner mitochondrial membrane. NADH cannot cross the membrane, but it can reduce another molecule that can cross the membrane, so that its electrons can reach the electron transport chain.

Which statement is TRUE? The membrane potential is negative on the cytoplasmic side and positive on the matrix side. The genomes of mitochondria don't range in size across species. The inner membrane is quite permeable because it contains mitochondrial porin, or VDAC (voltage-dependent anion channel). Mitochondria are semi-autonomous organelles, because mitochondria depend on the cell, and cells that contain mitochondria in turn depend on these organelles for oxidative phosphorylation. In bacteria, ATP-synthesizing complexes are located in the outer plasmatic membrane.

Fatty acid oxidation occurs in the mitochondrial matrix. However, long-chain fatty acyl-CoA molecules cannot cross the inner membrane to enter the matrix. The carnitine shuttle system transfers the acyl group from CoA to carnitine, which can enter the mitochondrial matrix.
Label the enzymes and compounds of the carnitine shuttle system. The following enzyme abbreviations are used: carnitine acyltransferase I, CAT1; mitochondrial carnitine acyltransferase II, CAT2; and carnitine/acylcarnitine translocase (carnitine carrier protein), CAT.

SELECT ALL THAT IS/ARE CORRECT: Why is the carnitine shuttle necessary for oxidation of fatty acids?...
SELECT ALL THAT IS/ARE CORRECT: Why is the carnitine shuttle necessary for oxidation of fatty acids? A.Because the lipid bilayer may confuse the incoming fatty acids as part of the membrane. Without the carnitine shuttle, the lipid bilayer may incorporate the fatty acids into the membrane instead of breaking it down via oxidation. B.Because fatty acids cannot directly pass through the mitochondrial membranes. C.Because fatty acids must be "tenderized" - i.e., multiple functional groups are added in order to facilitate...
