Isolated inner membrane of mitochondria can carry out:
1. the citric acid cycle
2. oxidative phosphorylation
3. glycolysis and fermentation
4. reduction of ${\mathrm{NAD}}^{+}$

The number of oxygen molecules required each time a molecule of glucose is completely oxidized via aerobic respiration is:

Let us say there are 30 NADH and 12 ${\mathrm{FADH}}_2$ in a mitochondrion. What is the maximum number of ATP generated if all dinucleotides are used in chemiosmosis?

Identify the incorrectly matched pair:

The correct chronological sequence of the stages of the glycolytic pathway is:

Fermentation regenerates:
1. ${\mathrm{O}}_2$
2. ${\mathrm{NAD}}^{+}$
3. acetyl-CoA
4. ATP

Chemiosmosis is coupled to energy storage by:

Ubiquinone is:
1. a protein in the mitochondrial electron transport chain
2. a substrate for synthesis of FADH
3. a vitamin used as coenzyme in Krebs cycle
4. a small hydrophobic coenzyme

A multienzyme complex amongst the following would be:

To generate a proton gradient, in mitochondria, the protons are pumped:
1. into the cytosol from the mitochondria
2. from the mitochondrial matrix into the intermembrane space of the mitochondria
3. from the cytosol into the matrix of the mitochondria
4. out of the nucleus and into the mitochondria
