Biochemistry MCQs

Polymerase chain reaction is a method that amplifies a selected DNA sequence through repeated thermal cycles.

Glycolysis is a cytosolic pathway that converts glucose to pyruvate while generating ATP and NADH.

Transamination is transfer of an amino group between an amino acid and a keto acid.

Vitamin B12 is a cofactor required for methionine synthase and methylmalonyl-CoA mutase reactions.

Albumin is the major plasma protein contributing to oncotic pressure and transport of many substances.

Lactate dehydrogenase is an enzyme that interconverts pyruvate and lactate while cycling NADH and NAD+.

Transamination is transfer of an amino group between an amino acid and a keto acid.

Polymerase chain reaction is a method that amplifies a selected DNA sequence through repeated thermal cycles.

Glycolysis is a cytosolic pathway that converts glucose to pyruvate while generating ATP and NADH.

Urea cycle is a hepatic pathway that converts toxic ammonia into urea for excretion.

Beta oxidation is mitochondrial degradation of fatty acids to acetyl-CoA units.

Glycogen phosphorylase is an enzyme that releases glucose-1-phosphate from glycogen during glycogenolysis.
