Final answer:
Hexokinase has a greater capacity to convert glucose to glucose-6-phosphate compared to glucokinase.
Step-by-step explanation:
The enzyme that has a greater capacity to convert glucose to glucose-6-phosphate is hexokinase. Hexokinase is found in nearly every tissue in the body and has a higher affinity for glucose compared to glucokinase. With its higher affinity, hexokinase is able to convert glucose at a faster rate than glucokinase.
