Hexokinase catalyzes the first step of glycolysis, in which glucose is phosphorylated to form glucose-6-phosphate. Which of these statements are accurate? The conformational shift that occurs when glucose, but nox water, enters the active site prevents water from hydrolyzing ATP Most kinases require the presence of a monovalent metal ion cofactor to prevent ATP hydrolysis. Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. Hexokinase consists of two domains, or lobes, that come together when glucose and...
what happens to the glucose molecule in the first step of glycolysis
Recall the first three reactions in glycolysis: You’ve already learned that, in addition to proceeding through glycolysis, glucose 6-phosphate (G6P) can be used to synthesize a carbohydrate storage molecule called glycogen. Glucose 6-phosphate is also a precursor for the synthesis of nucleotides that are used to build DNA and RNA. The first step of this pathway is catalyzed by an enzyme called glucose 6-phosphate dehydrogenase. Assume that reactions in this pathway with double arrows are reversible under cellular conditions, while...
14. The second step of glycolysis is the following reaction: Glucose-6-phosphate = Fructose-6-phosphate At pH 7 and 25 °C, IM of G6P and F6P will equilibrate to [F6P]/[G6P] = 2.43.
