Question

The two 3-carbon molecules in which glucose is split, are converted through a series of steps into the final 3-carbon molecule. During these later steps, ________ molecule(s) of ATP are made.

Answer 1

Answer: four (4)

Explanation:

The two 3-carbon molecules in which glucose is split are DIHYDROXYACETONE and GLYCERALDEHYDE 3-PHOSPHATE.

These two are ISOMERS and are converted through a series of five steps into the final 3-carbon molecule called PYRUVATE, CH3COCOO

During these later steps KNOWN as the PAYOFF phase (phase II) of glycosis, FOUR (4) molecules of ATP are made.
