(A) Lactate Pyruvate
(B) Phosphoenol pyruvate pyruvate
(C) Oxaloacetate phosphoenol pyruvate
(D) Glucose-6-phosphate Fructose-6-phosphate

(A) Lactate
(B) Glycerol
(C) α-ketoglutarate
(D) Acetyl CoA

(A) The conversion of Glucose to lactate occurs
only in the R.B.C
(B) Glucose enters most cells by a mechanism in
which Na+ and glucose are co-transported
(C) Pyruvate kinase catalyses an irreversible
reaction
(D) An elevated level of insulin leads to a
decreased level of fructose 2, 6-bisphosphate
in hepatocyte

(A) Increased levels of lactate in the R.B.C
(B) Hemolytic anemia
(C) Decreased ratio of ADP to ATP in R.B.C
(D) Increased phosphorylation of Glucose to
Glucose-6-phosphate

(A) An increased conversion of pyruvate to lactate
(B) Decreased oxidation of pyruvate of CO2 and
water
(C) A decreased NADH/NAD+ ratio
(D) Decreased concentration of AMP

(A) Is activated by high concentrations of ATP and
citrate
(B) Uses fruitose-1-phosphate as substrate
(C) Is the rate-limiting reaction of the glycolytic
pathway
(D) Is inhibited by fructose 2, 6-bisphosphate

(A) Is widely distributed and occurs in most
mammalian tissues
(B) Has a high km for glucose and hence is
important in the phosphorylation of glucose
primarily after ingestion of a carbohydrate
rich meal
(C) Is widely distributed in Prokaryotes
(D) None of these

(A) It is located on the matrix side of the inner
mitochondrial membrane
(B) is inhibited by oligomycin
(C) It can exhibit ATPase activity
(D) It can bind molecular O2
