What are two advantages of the components of the electron transport chain being embedded in the inner mitochondrial membrane?

In human cells, where does fatty acid elongation (that is, beyond the C16:0 normally produced by fatty acid synthase) occur?   a)On the outer (cytosolic) face of the outer mitochondrial membrane b)On the outer (cytosolic) face of the endoplasmic reticulum membrane c)Free in the cytosol d)In the mitochondrial matrix

Which of the following is required to transport fatty acids across the inner mitochondrial membrane? (A) Acyl carrier protein (B) Albumin (C) Carnitine (D) Chylomicrons (E) Creatinine (F) Lecithin-cholesterol acyltransferase

In the 1930’s DNP was given to people to lose weight.  DNP makes the mitochondrial membrane leaky to hydrogen ions.  Why might this cause one to lose weight?  Why would this cause death?  How is this similar or different to cyanide which binds to complex IV in the mitochondria?

Which of the following does not occur in the mitochondria? A) Krebs cycle C) glycolsis D) electron transport

What uncharged substrate molecule is reduced to 2 molecules of water, in the mitochondrial electron transport chain, by the addition of exactly 2 protons and 2 electrons to this molecule (by complex IV)? one molecule of diatomic oxygen gas one molecule of the superoxide free radical one molecule of hydrogen peroxide one molecule of the hydroxyl free radical one molecule of the hydroxide ion

You are studying the enzyme kinetics of enzymes in the TCA cycle.  You add a molecule to the mixture that appears to act as a competitive inhibitor of one of the enzymes.  At first, you cannot tell which enzyme is inhibited, but you can tell that it is bound to the inner mitochondrial membrane.  Can you guess which TCA enzyme you have inhibited and how do you know? Where are other enzymes located in the mitochondrion?

Assume there is no cyanide poisoning. What would happen if the inner mitochondrial membrane was permeabilized to the point where it no longer served as a barrier, affecting the proton gradient and ATP synthesis?

Which complexes of the electron transport system are able to catalyze the synthesis of ATP from ADP to Pi?

In a cell undergoing respiration, you would expect pH in the relative to that on the other side of the inner mitochondrial membrane. A) higher, B) higher, C) lower, D) the same, intermembrane space mitochondrial matrix mitochondrial matrix intermembrane space
