Question
Hexokinase catalyzes the first step of glycolysis, in which glucose is phosphorylated to form glucose-6-phosphate. Which of the following statements are accurate? Choose all that apply. Hexokinase is found in the cytosol. Kinases require the presence of a metal ion such as Mg^2+ or Mn^2+, which forms a complex with ATP. Hexokinase consists of two domains, or lobes, that come together when glucose and the MgATP^2- complex are bound. Hexokinase is a type of phosphatase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. Because hexokinase brings the OH of glucose close to ATP, the hydroxyl group of water can enter the active site and hydrolyze ATP to ADP and Pi.Explanation / Answer
Your last option is incorrect, however, and basing on the statement of your mistake, the correct option would be 4th. Hexokinase does acts as catalyst. Try this option.
Hope this helps
