Identify the incorrectly matched pair:

	Component of ETC	Name
1.	Complex I	NADH dehydrogenase
2.	Complex II	Succinate dehydrogenase
3.	Complex III	Cytochrome b6f complex
4.	Complex IV	Cytochrome c oxidase

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

The pathway that normally occurs whether or not oxygen is present would be would be:
I. glycolysis
II. fermentation
III. citric acid cycle
1. Only I
2. I and II only
3. II only
4. III only

The processes that occur in the cytosol of a eukaryotic cell is/are:
I. glycolysis
II. fermentation
III. oxidation of pyruvate to acetyl CoA

The corresponding yield of ATP from one molecule of ${\mathrm{FADH}}_2$ is:
