Question

Given below are some reactions and the enzymes involved. Identify the correct pairs.

	I.		II.
$1$.	Fructose $1,6$ diphosphate $\to 3$PGAL $+$ DHAP	a.	Enolase
$2$.	Citrate $\to$Cis - aconitate	b.	Thiokinase
$3$.	Succinyl Co. A $\to$ Succinate	c.	Aconitase
$4$.	$2$PGA$\to$ PEPA	d.	Aldolase

• A. 1- d, 2- c, 3- b, 4- a
• B. 1- a, 2- b, 3- c, 4- d
• C. 1- b, 2- a, 3- d, 4- c
• D. 1- c, 2- b, 3- a, 4- b

Answer 1

The correct option is A 1- d, 2- c, 3- b, 4- a

Reactions 1. and 4. belong to the Glycolysis.

When Fructose 1,6 diphosphate convert to a 3 carbon (glyceraldehyde-3-phosphate) and DHAP, the enzyme aldolase is used.

When 2 (2-phosphoglycerate ) converts to 2 (2-phosphoenolpyruvate) the enzyme enolase is used.

The reaction 2. and 3. belong to Kreb cycle

When Citrate converts to cis-aconitate then enzyme aconitase is used.

When Succinyl Co. A convert to Succinate then Thiokinase is used.

So, the correct option is '1- d, 2- c, 3- b, 4- a'
