Vedclass · Accepted Answer

In fermentation there is a net gain of only two molecules of $ATP$ for each molecule of sucrose degraded to pyruvic acid.

Vedclass · Answer

(C) $1$. Fermentation involves the partial breakdown of glucose into ethanol or lactic acid,which is correct.$2$. Aerobic respiration yields significantly more $ATP$ molecules compared to fermentation,which is correct.$3$. In fermentation,glucose is broken down into pyruvic acid,and then further into ethanol or lactic acid. The net gain of $ATP$ is $2$ molecules per glucose molecule. However,the statement mentions sucrose. Sucrose is a disaccharide that breaks down into glucose and fructose. Therefore,the degradation of one molecule of sucrose yields $4$ molecules of $ATP$ (as it produces two glucose units),not $2$. Thus,this statement is incorrect.$4$. In aerobic respiration,$NADH$ is oxidized to $NAD^+$ through the electron transport system,which is correct.
