Vedclass · Answer

(D) Glycolysis is the process of breakdown of glucose or similar hexose sugar into two molecules of pyruvic acid through a series of enzyme-mediated reactions,releasing energy $(ATP)$ and reducing power $(NADH_2)$.It is the first step of respiration,which occurs inside the cytoplasm and is independent of $O_2$.In glycolysis,two molecules of $ATP$ are consumed during the double phosphorylation of glucose to form fructose $1, 6$-diphosphate.Four molecules of $ATP$ are produced in the conversion of $1, 3$-diphosphoglycerate to $3$-phosphoglycerate and phosphoenolpyruvate to pyruvate.Additionally,two molecules of $NADH_2$ are formed during the oxidation of glyceraldehyde $3$-phosphate to $1, 3$-diphosphoglycerate.Since each $NADH$ is equivalent to $3\, ATP$,the net gain in glycolysis is $8\, ATP$.Therefore,both the Assertion and the Reason are incorrect.

$c.$ Fumarate	$iii.$ $6 \ C$-compound
$d.$ $1,3$-diphosphoglyceric acid	$iv.$ $5 \ C$-compound

Assertion : Glycolysis is the first step of respiration in which glucose completely breaks into $CO_2$ and $H_2O$.
Reason : In this process,there is net gain of twenty four molecules of $ATP$.
