Question

1. Both viruses and prokaryotes reproduce by binary fission. Select one: a. True b. False

2. Fermentation makes only small amounts of ATP molecules . Select one: a.True b. False

Answer 1

1Q) answer: False

reason:

bacteria is the best example of prokaryotes and these are single-celled organisms. these are not dependent on other organisms for reproduction. bacteria commonly reproduce asexually by a process binary fission. binary fission means single cell divides to form two identical daughter cells. then coming to viruses, these are very small in size compare to bacteria. viruses are dependent on other host cells for reproduction because viruses do not contain organelles required for reproduction. suppose viruses entering into the body, after entering the virus use host organelles for reproduction.

2Q) True

reason:

fermentation means the conversion of carbohydrates into alcohol or lactic acid by using enzymes. fermentation and glycolysis process takes place in the cytoplasm. glycolysis pathway occurs in anaerobic organisms, in these process glucose converts to form pyruvate. fermentation is followed by the glycolysis process to continue to produce ATP molecules. in fermentation, only 2 ATP molecules produce because in the glycolysis process NADH is produced but these all NADH are consumed in the fermentation process so that why fermentation makes a small amount of ATP molecules. and fermentation process also not enter into the electron transport chain due to lack of NADH.
