ATP synthesis during oxidative phosphorylation in mitochondria is directly driven by:
1. oxidation of glucose.
2. electron transport downhill in the ETC.
3. terminal transfer of electrons to oxygen.
4. chemiosmosis.

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?

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

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:

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:

All the following will normally occur during the electron flow in ETS in mitochondria except:
1. NADH and ${\mathrm{FADH}}_2$ are oxidized.
2. the pH of the matrix decreases.
3. the electrons lose free energy.
4. an electrochemical gradient is formed.

Fats and proteins can also provide us energy. For this to happen:
1. Fats and proteins must first be converted to glucose
2. Fats and proteins must enter separate catabolic pathways of their own
3. Fats and proteins must be modified to forms that can enter the glucose metabolic pathway
4. Fats must first be converted to proteins that can enter the glucose metabolic pathway
