Question
Which of the following is the CORRECT statement with respect to the steps involved in glycolysis?
Options
DHAP and PEPA are the products of cleavage in glycolysis.
In glycolysis, dehydration occurs when 3- PGAL loses a water molecule (dehydration) to form PEPA.
3-PGAL undergoes oxidation and phosphorylation to form 1,3-diPGA.
PEPA is phosphorylated to pyruvic acid in the presence of the enzyme pyruvate dehydrogenase.
Solution
3-PGAL undergoes oxidation and phosphorylation to form 1,3-diPGA.
Explanation:
DHAP (dibydroxy acetone phosphate) and 3-phosphoglyceraldehyde (3-PGAL) is a kind of phosphoglyceraldehyde. cleavage products in glycolysis Dehydration develop during glycolysis. A water molecule is lost by 2-phosphoglyceric acid. Phosphoenol pyruvic acid is formed during dehydration. Dephospborylation of phosphoenol pyruvic acid in the presence of the enzyme to pyruvic acid pyruvate kinase is a pyruvate kinase enzyme.
