An enzyme used in gluconeogenesis but NOT glycolysis is:Group of answer choicesglucose 6-phosphatasephosphofructokinase-1pyruvate kinasehexokinase

Gluconeogenesis, must bypass irreversiblereactions of glycolysis, except:a. Hexokinaseb. Phosphohexose isomerasec. Pyruvate kinased. Phosphofructokinase

The phosphorylation of glucose to glucose-6-P in the glycolysis pathway is catalyzed by glucokinase. Which enzyme in the gluconeogenesis pathway catalyzes the reverse reaction (G6P > Glucose)? A. Glukose-6-fosfatase / Glucose-6-phosphatase B. Piruvaatkinase / Pyruvate kinase C. Heksokinase / Hexokinase D. Fosfofruktokinase / Phosphofructokinase E. Fruktose-1,6-bifosfatase / Fructose-1,6-bisphosphatase

Which enzyme is primarily responsible for initiating glycogenolysis?Question 13Answera.Glycogen synthaseb.Glycogen phosphorylasec.Hexokinased.Glucokinase

The first ATP forming reaction in glycolysis is catalysed by which enzyme?Group of answer choicesglyceraldehyde 3-phosphate dehydrogenasephosphofructokinase-1phosphoglycerate kinasehexokinase

Glucose units cleaved from glycogen by the phosphorylase:Group of answer choicesneed to have their 1-phosphate moved to the C6 position before they can enter glycolysisare converted into fructose 1-phosphate and then enter glycolysis at step 3directly enter glycolysis at step 2, where they are converted to fructose 6-phosphateare phosphorylated at the C1 position by hexokinase to generate glucose 1-phosphate
