The conversion of glucose to fructose for the industrial production of high-fructose corn syrup is carried out by the enzyme

A. Cellulase
B. Lactase
C. Glucose isomerase (Xylose isomerase)
✓
D. Sucrase

📝 Explanation

The enzyme glucose (xylose) isomerase catalyzes the reversible isomerization of glucose to the sweeter fructose. This process is used to convert a portion of the glucose from corn starch into fructose, creating high-fructose corn syrup (HFCS).
