Question

47) The total ATP production per molecule of glucose in prokaryotes is considered to be while in eukaryotes it is believed to be between a) 36; 32-34 b) 38;25-36 c) 6;3 d) 22; 36-38 e) 38; 3-6 48) The transition step, Krebs cyele and the electron transport system all take place in the of Prokaryotic cells. a) ribosomes b) endoplasmic reticulum c) lysosomes d) nucleus e) cytoplasm/plasma membrane 49) A relatively small number of known bacterial species utilize the sun as their source of energy and organic chemicals as their source of carbon are classified as: a) photochemotrophs b) photoautotrophs cchemoautotrophs d) photoheterotrophs e) chemoheterotrophs 50) The process of cellular respiration whereby electrons are passed through a series of oxidation-reduction reactions via coenzymes and cytochromes ultimately releasing their energy to ADP+ P is termed the: a) electron transport system b) citric acid cycle c) Entner-Dourdoff pathway d) hexose-monophosphate shunt e) transformation EXTRA CREDIT: (One point each) 51) Bacteria cells found with flagella scattered over their entire cell surface are classified as a) amphitrichous b) lophitrichous c) ambidextrous d) peritrichous e) monotrichous

Explanation / Answer

47) Prokaryotes always produce 38 ATPs during aerobic respiration(since they lack shuttle system) whereas eukaryotes produces 36-38 ATPs (most commonly 36 ATPs). But in the question there is no options appropriately matching with the data. So the more correct option is (b) 38, 25-36.

48) In prokaryotes krebs cycle and electron transport system takes place in Cytosol (cytoplasmic matrix). So according to the question the correct answer would be option (e) cytoplasm/plasma membrane.

49) The correct answer is option (d) photoheterotrophs. These are the organisms that derive energy from Sun and depends on organic compounds for the source of carbon.

50) The correct option is (a) electron transport system.

51) The correct option is (d) peritrichous.
