When electron pass downhill in the ETC, the energy released is used to pump protons into:
1. matrix of mitochondria
2. cytosol
3. mitochondrial inner membrane
4. mitochondrial intermembrane space

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.

ATP synthase is located in the mitochondrial:

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:
