Vedclass · Accepted Answer

Glycogen

Vedclass · Answer

(A) The respiratory substrate that yields the maximum number of $ATP$ molecules is a polysaccharide like glycogen. Glycogen is a polymer of glucose. When glycogen is broken down into glucose$-1-$phosphate and then enters the glycolytic pathway,it bypasses the initial phosphorylation step that consumes $1$ $ATP$ molecule. Therefore,the net yield of $ATP$ from the oxidation of a glucose unit derived from glycogen is slightly higher than that of free glucose. Among the given options,glycogen is the most efficient respiratory substrate for $ATP$ production.

Stages	$ATP$ produced through $ETS$
$A$. Glycolysis	$1$. $6$
$B$. Formation of Acetyl $CoA$ from Pyruvic acid	$2$. $3$
$C$. Kreb's cycle	$3$. $24$
