Question

Two enzymes common to EMP pathway and C₃
cycle are
(a) aldolase and triose phosphate isomerase
(b) aldolase and enolase
(c) cytochrome oxidase and enolase
(d) phosphoglyceromutase and triose phosphate
isomerase

Answer 1

ANSWER

In the EMP pathway or glycolysis, a 6-carbon fructose 1,6- biphosphate is formed which is acted upon by aldolase and phosphotriose isomerase to form 3-PGA and DHAP in dynamic equilibrium. This same pair of an enzyme is also employed in the C3 cycle in which a 6-carbon intermediate is decayed by it to form two molecules of 3-PGA.

So the answer is 'Aldolase and triose phosphate isomerase'.
