Answer 1

84) The end product of the glycolysis is pyruvate ,which is a 3 carbon molecule.Pyruvate is also a metabolite of glucose.

So answer is E)all of the above.

85)Glycolysis breaks down glucose into metabolites.So it is an example of catabolism.

So answer is B.

86)Pyruvate enters the tricarboxylic acid cycle.

So answer is A.

87)In bacteria, the electron transport chain is located in the plasma membranes.

So answer is D.

88) Electron transport chain leads to the production of H2O and ATP.

So answer is A.

89)Production of ATP in electron transport chain is driven by proton motive force.

So answer is D.

90)ATP synthase is a protein ,not carbohydrate. So C is ruled out.

It's an enzymatic protein.So d is ruled out.

It is not present on cell surface.So A is ruled out.

It is a proton carrier,not electron carrier.So B is ruled out.

So answer is E.
