Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What enzyme is responsible during the splitting of fructose 1.6-Bisphosphate into Glyceraldehyde 3-phosphate (G3P) and Dihydrocyacetone phosphate (DHAP)?
A
Triose phosphate isomerase
B
Aldolase
C
Pyruvate
D
Phosphoglycerate mutase
Explanation: 

Detailed explanation-1: -Aldolase. Aldolase is a glycolytic enzyme that catalyzes the conversion of fructose 1-6-diphosphate to glyceraldehyde 3-phosphate and dihydroxy-acetone phosphate via the glycolysis metabolic pathway.

Detailed explanation-2: -Fructose 1, 6-bisphosphate aldolase is a ubiquitous cytosolic enzyme that catalyzes the fourth step of glycolysis. Aldolases are classified into three groups: Class-I, Class-IA, and Class-II; all classes share similar structural features but low amino acid identity.

Detailed explanation-3: -Fructose-bisphosphate aldolase (EC 4.1. 2.13), often just aldolase, is an enzyme catalyzing a reversible reaction that splits the aldol, fructose 1, 6-bisphosphate, into the triose phosphates dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate (G3P).

Detailed explanation-4: -Glycolysis Enzymes : Example Question #2 Explanation: Dihydroxyacetone phosphate (DHAP) is converted to glyceradehyde-3-phosphate (G3P) by the enzyme triose phosphate isomerase. As the name suggests, this enzyme catalyzes the isomerization of a three-carbon sugar into another three-carbon sugar.
