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

Which of the following exhibits the highest rate of respiration?

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?

Consider the steps of glycolysis given in the diagram:
  
Regarding reaction 3 in the diagram:

1. Only I is true
2. Only II is true
3. Both I and II are true
4. Both I and II are false

In aerobic respiration, oxygen acts as:
I. Terminal electron acceptor
II. Terminal proton acceptor
