Vedclass · Answer

(B) $1$. Glycolysis is an anaerobic process where glucose is converted into pyruvic acid without the requirement of oxygen. Thus,option $A$ is correct.$2$. In eukaryotic organisms,the net gain of $ATP$ during aerobic respiration is typically $36$ or $38 \ ATP$ molecules,not $42$. Thus,option $B$ is incorrect.$3$. Carbohydrates are the primary respiratory substrates used by cells to produce energy. Thus,option $C$ is correct.$4$. Glycolysis involves substrate-level phosphorylation,not oxidative phosphorylation. Furthermore,the net gain of $ATP$ in glycolysis is $2 \ ATP$,not $6$. Thus,option $D$ is also incorrect. However,in the context of standard multiple-choice questions where one must identify the most glaring error regarding respiratory yields,$B$ and $D$ are both factually wrong. Given the standard curriculum,$D$ is often cited as a common misconception regarding the mechanism of $ATP$ production in glycolysis.
