Negative Insulin has effect on glycogen synthesis. a. Positive b. Negative Glucagon has effect on glycogen synthesis a. Positive b. NegativeExplanation / Answer
15. Glycolysis means breaking down of glucose to three carbon containing sugar Pyruvate. It yields two molecules of ATP, different steps involved in it are catalysed by enzymes like hexokinase, phospho fructokinase, pyruvate kinase. The reactions are irreversible hence, these enzymes would be expected to have regulatory as well as catalytic roles. G3P dehydrogenase is not a control point in glycolysis.
answer : G3P dehydrogenase
16. Gluconeogenesis (GNG) is a metabolic pathway that results in the generation of glucose from certain non-carbohydrate carbon substrates.
answer : GLUCOSE
17. Cori cycle refers to the metabolic pathway in which lactate produced by anaerobic glycolysis in the muscles moves to the liver and is converted to glucose, which then returns to the muscles and is metabolized back to lactate.
answer : GLYCOLYSIS IN MUSCLE CELL
18. Insulin is a harmone which converts extra glucose in our body to glycogen and stores it in liver.
answer : it has negative effect on gluconeogenesis.
19.Glucagon stimulates the break down glycogen to glucose.
answer : it has positive effect on gluconeogenesis
20.
Insulin is a harmone which converts extra glucose in our body to glycogen and stores it in liver.
answer : it has positive effect on glycogen synthesis.
21.
Glucagon stimulates the break down glycogen to glucose.
answer : it has negative effect on glycogen synthesis.
