Vedclass · Answer

(A) During aerobic respiration, the complete oxidation of one molecule of glucose occurs through glycolysis, the link reaction, the Krebs cycle, and the electron transport system $(ETS)$.In eukaryotic cells, the net gain of $ATP$ is typically $36$ molecules.This is because $2$ $ATP$ are produced in glycolysis, $2$ $ATP$ (or $GTP$) in the Krebs cycle, and the remaining $ATP$ are generated via oxidative phosphorylation in the $ETS$ using the $NADH$ and $FADH_2$ produced.While some older textbooks mention $38$ $ATP$, the modern consensus accounting for the cost of transporting $NADH$ into the mitochondria (via the malate-aspartate shuttle or glycerol-phosphate shuttle) results in a net yield of $30$ to $32$ $ATP$ in many tissues, but $36$ remains the standard answer in many academic contexts for eukaryotic aerobic respiration.

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