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:

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:
