Most of the enzymes of glycolysis are reversible. But three are not and these are:Select one alternative:phosphofructokinase, fructose 1,6-bisphosphatase, and glucose 6-phosphatasepyruvate socratase, isosolase and fructose 1,6-pythagorasepyruvate kinase, phosphofructokinase and hexokinasepyruvate carboxylase, phosphoenolpyruvate carboxykinase and fructose 1,6-bisphosphatase

During glycolysis, phosphofructokinase converts fructose 6-phosphate (F6P) into fructose 1,6-bisphosphate (F1,6BP), as shown below.  Aldolase then converts F1,6BP into glyceraldehyde 3-phosphate (GAP) and dihydroxyacetone phosphate (DHAP).Respectively, phosphofructokinase and aldolase are examples of:A.an isomerase and a hydrolase.B.a transferase and a lyase.C.a ligase and an isomerase.D.an oxidoreductase and a transferase.

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

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

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

Which of the following enzymes are most likely to be regulated in glycolysis?Group of answer choicesA) all enzymes in glycolysis are potential regulation pointsB) enzymes that catalyze reversible steps are most likely to be regulatedC) hexokinase and pyruvate kinaseD) the first three enzymes of the pathway, since regulation is most efficient if it occurs at the beginning of a pathwayE) enzymes like aldolase, which catalyze big chemical changes like cleavage of C—C bonds
