Hexokinase catalyzes the first step of glycolysis, in which glucose is phosphorylated to form glucose‑6‑phosphate. Which of these statements are accurate? a. Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. b. Hexokinase consists of two domains, or lobes, that come together when glucose and the MgATP2 - complex are bound. Kinases require the presence of a metal ion such as Mg2 + or Mn2+, which forms a complex with ATP. c. Hexokinase is a type of phosphatase that catalyzes the transfer of a phosphoryl group from ATP to a hexose. d. Hexokinase is found in the mitochondrial membrane. e. The conformational shift that occurs when glucose, but not water, enters the active site prevents water from hydrolyzing AT

The accurate statements are given below.

Explanation:

b Hexokinase consist of two domains or lobes that comes together when glucose and MgATP2 - complex are bound. kinase requires the presence of a metal ion such as Mg2 + or Mn2 + which forms a complex with ATP.

e The conformational shift that occurs when glucose but not water enter the active site prevents water from hydrolyzing ATP.
