Question

1.

Which of the following occurs during aerobic cellular respiration?

		Acetyl-CoA is converted into pyruvate.
		2 pyruvate molecules are converted into glucose.
		NADH and FADH2 get produced during the Krebs Cycle.
		Glycolysis produces carbon dioxide.
		None of the above.

2.

With respect to aerobic respiration, which function: location relationship is INCORRECT?

		Acetyl-CoA production; mitochondrial matrix
		FADH2 production; mitochondria matrix
		Pyruvate production; mitochondria matrix
		ATP synthase; inner mitochondrial membrane
		None of the above

3.

Which of the following is FALSE about the hydrolysis of ATP?

		The hydrolysis of ATP is an exergonic reaction.
		The hydrolysis of ATP is used as the exergonic reaction in many coupled reactions.
		When ATP is hydrolyzed, the products have more free energy than the reactants.
		None of the above.

Which of the following is NOT a difference between bacteria and eukaryotes?

		eukaryotic cells have a nucleus while bacterial cells do not
		bacterial chromosomes are usually circular while eukaryotic chromosomes are linear
		bacteria typically contain a single type of chromosome while the nucleus of eukaryotic cells typically contain a set of different types of chromosomes
		bacterial genes typically consist of a continuous stretch of coding DNA, while the protein coding sequences of eukaryotic genes are typically interrupted by non-coding regions
		None of the above

Answer 1

1) during aerobic cellular respiration NADH and fadh2 produced during Krebs cycle

The rest options are incorrect.

Acetyl coA is not converted to pyruvate instead pyruvate undergo oxidative decarboxylation to form acetyl coA.

Similarly pyruvate not converted to glucose instead glucose is converted to pyruvate during glycolysis.

Glycolysis don't produce CO2 instead it produces pyruvate ATP and NADH.

2) pyruvate production is not takes place in mitochondrial matrix instead it takes place in cytosol. Pyruvate is the product of glycolysis and it takes place in cytosol or cytoplasm of cell.

3)false is when ATP is hydrolyzed the products have more energy than the reactant. Instead when ATP is hydrolyzed the products i.e ADP and pi have lower energy than the reactant.

4)all above statements are correct. So none of the above is incorrect.
