  1. Question 1

    Q1. During the cleavage phase of glycolysis, two trioses are formed, but which one is directly used in the next step?

    • A) Dihydroxyacetone phosphate
    • B) 3-phosphoglycerate
    • C) Glyceraldehyde-3-phosphate
    • D) 2-phosphoglycerate

    Answer: Glyceraldehyde-3-phosphate

    Explanation: Only G3P continues; DHAP must be isomerized first. Fructose-1,6-bisphosphate is tempting as it is the precursor to both.
