Pyruvic acid, the key product of glycolysis can have many metabolic fates. Under aerobic condition, it forms

1.	Lactic acid	2.	CO2 + H2O
3.	Acetyl CoA + CO2	4.	Ethanol + CO2

What is the end product of glycolysis?

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:

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
