The following is a simplified scheme showing the fate of glucose during aerobic and anaerobic respiration. Identify the end products that are fomed at stages indicated as A, B, C and D. Identify the correct option form those given below

Options

A. A= carbon dioxide and water, B= pyruvic acid, C= ethyl alcohol and carbon dioxide, D= lactic acid
B. A= pyruvic acid, B= carbon dioxide and water, C= lactic acid, D= ethyl alcohol and carbon dioxide
C. A= pyruvic acid, B= carbon dioxide and water, C= ethyl alcohol and carbon dioxide, D= lactic acid
D. A= pyruvic acid, B= ethyl alcohol and carbon dioxide, C= lactic acid, D= carbon dioxide and water

Answer

B

Explanation

Aerobic respiration : Breakdown of glucose in the presence of oxygen to form pyruvic and `CO_2` ATP is called aerobic respiration.
Anaerobic respiration : Breakdown of glucose in the absence of oxygen to form pyurvic acid and then undergo fermentation to produce ethanol in the presence of feast and lactic acid in humans and bacteria.
Glucose `rarr` Pyruvic acid `("Anaerobic Respiration" -CO_2 + 38"ATP" )/("Aerobic Respiration")`
`{:("Alcoholic fermentation","Lactic acid fermentation"),("(Formation of Ethanol in","(Formation of lactic acid"),("the presence of yeast)","in human and bacteria)"):}`
