Solution To Questions From Carbohydrate Metabolism (Choose The Correct Answer)
Choose the correct Answer
1) Glucose is mainly absorbed by passive diffusion/ active transport.
2) GLUT-4 transporters are present in adipose tissues/red blood cells.
(Adipose tissues )
3) Insulin promotes Glycolysis/Glycogenolysis.
4) Lactase/ Lactate dehydrogenase is deficient in lactose intolerance.
5) In type 2 diabetes mellitus, the peripheral cells become oversensitive/ Insensitive to the effect of insulin.
6) Phosphorylase enzyme is active in the phosphorylated / dephosphorylated form.
7) Sorbitol is produced by the oxidation/reduction of glucose.
8) Glucokinase/ Hexokinase can regulate the blood glucose level.
9) Chronic alcohol ingestion can produce hypoglycemia/hyperglycemia.
10) Glucose-6- phosphatase / Glucose-6-phosphate dehydrogenase is deficient in Von- Gierke’s disease.
(Glucose-6- phosphatase )
11) More the concentration of 2,3bisphosphoglycerate more/less will be the unloading of oxygen to the peripheral tissues.
12) Glycated Hb is represented by HbAIa/HbAIc.
13) Ca ++ /Mg++ can activate phosphorylase kinase without phosphorylation.
( Ca ++)
14) Hypokalemia/Hyperkalemia is observed on treatment with insulin in diabetes mellitus.
15) Hypercholesterolemia/Hypocholesterolemia is observed in type 2 diabetes mellitus.
16) ATP and Citrate are negative/positive modifiers of PFK-I enzyme.
17) 51/53 amino acids are present in mature insulin.
18) A low/ high ATP to ADP ratio is a stimulant for PDH kinase enzyme.
19) Hexokinase/ Glucokinase enzyme is inhibited by feed back inhibition.
20) The preferred source of energy for the brain cells is glucose/ketone bodies.
21) During overnight fasting blood glucose is maintained by Gluconeogenesis/ Glycogenolysis.
22) Transketolase/ Transaminase is TPP dependent.
23) Free Glucose/ Glucose-1-phosphate is the end product of debranching enzyme catalyzed breakdown of glycogen.
24) The half-life of Insulin is 5 minutes/5 hours.
25) Sorbitol dehydrogenase enzyme is absent in liver/ nerves.
26) 36 ATP/ 38 ATP molecules are produced by the complete oxidation of 1 molecule of glucose under aerobic conditions.
27) Malonate/ Oxamate is the inhibitor of Succinate dehydrogenase enzyme.
28) The enzymes of TCA cycle are present in the mitochondria/ Cytoplasm.
29) Pyruvate/ Lactate is the end product of glycolysis under anaerobic conditions.
30) No ATP/ 2 ATP when RL shunt is operating in the red blood cells.
