Vedclass · Answer

(B) In the process of glycolysis,the conversion of glucose to glyceraldehyde-$3$-phosphate occurs in the preparatory phase.$1$. First,glucose is phosphorylated to glucose-$6$-phosphate by the enzyme hexokinase,which consumes $1$ $ATP$ molecule.$2$. Then,glucose-$6$-phosphate is isomerized to fructose-$6$-phosphate.$3$. Finally,fructose-$6$-phosphate is phosphorylated to fructose-$1,6$-bisphosphate by the enzyme phosphofructokinase,which consumes another $1$ $ATP$ molecule.$4$. Fructose-$1,6$-bisphosphate is then split into glyceraldehyde-$3$-phosphate and dihydroxyacetone phosphate.Thus,a total of $2$ $ATP$ molecules are consumed in this phase.

During cellular respiration,the number of $ATP$ molecules used during the conversion of glucose into glyceraldehyde-$3$-phosphate is:
