What is the end product of glycolysis?

1. NADH	2. ATP
3. G3P	4. Pyruvate

The outputs of the Krebs cycle do not include:

The products of fermentation do not include:

Oxidative decarboxylation of pyruvate produces:

The stage of cellular respiration that directly involves oxygen is:

${\mathrm{FADH}}_2$ 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
