Answer & Solution

Correct Answer

(C) Step 1 and 3

Step-by-step Solution

Detailed explanation

Step 1: A glucose molecule is phosphorylated to glucose 6-phosphate in presence of enzyme hexokinase and co-factor \(Mg ^{++}\). In this reaction, ATP supplies the phosphate and gets converted into ADP. Step 3: Fructose-6-phosphate is phosphorylated to fructose-1,6-diphosphate and ADP. Phosphate is supplied by ATP which gets converted to ADP.
