Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Name of enzyme that forms glucose 6 phosphate from glucose is
A
Hexo kinase
B
Isomerase
C
Aldolase
D
Enolase
Explanation: 

Detailed explanation-1: -Complete answer: Hexokinase is the enzyme that converts glucose to glucose-6-phosphate. The most important substrate for hexokinase is glucose and glucose 6 phosphate that are the most important products.

Detailed explanation-2: -Hexokinase converts glucose to glucose 6-phosphate, trapping the glucose molecule inside the cell, thus starting off the process of glycolysis.

Detailed explanation-3: -The enzyme glucose 6-phosphatase (EC 3.1. 3.9, G6Pase; systematic name D-glucose-6-phosphate phosphohydrolase) catalyzes the hydrolysis of glucose 6-phosphate, resulting in the creation of a phosphate group and free glucose: Glucose 6-phosphatase. EC no.

Detailed explanation-4: -So the correct answer is ‘Hexokinase’.

Detailed explanation-5: -Hexokinase is a protein which is classified under the main grouping of a transferase enzyme. Its structure was first determined from yeast by Tom Steitz at Yale University. Hexokinase is the first enzyme in the glycolytic pathway, and it converts glucose into glucose-6-phosphate.
