The products of fermentation do not include:

1.	CO2	2.	O2
3.	ethanol	4.	lactate

Oxidative decarboxylation of pyruvate produces:

The stage of cellular respiration that directly involves oxygen is:

What process in aerobic respiration generates maximum ATP?

${\mathrm{FADH}}_2$ is produced in

Krebs cycle is also called as:

The correct sequence of flow of electrons downhill in the mitochondrial electron transport chain would be:
1. ubiquinone, cytochromes, FMN, Fe-S
2. cytochromes, FMN, ubiquinone, Fe-S
3. Fe-S, FMN, cytochromes, ubiquinone
4. FMN, Fe-S, ubiquinone, cytochromes

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.
