Answer #1

Answer:

  • Pyruvate can be decarboxylated by at least two pathways.
  • Pyruvate can be converted into malate via several steps.

Explanation:

  • Pyruvate decarboxylation takes place in two pathways, one in the conversion of pyruvate to acetyl coA, and the other in the conversion of pyruvate to acetaldehyde.
  • Pyruvate can be converted directly into malate or by first converting the pyruvate into oxaloacetate and then converting it into malate.
