Chapter 23: Q18P (page 829)

Describe how the fumarate produced by the purine nucleotide cycle could be catabolized to CO2.

Short Answer

Expert verified

The citric acid cycle can catabolize the fumarate generated by the purine nucleotide cycle to CO2.

Step by step solution

01

Description of Fumarate.

The purine nucleotide cycle produces fumarate as aconsequence of adenosine monophosphate (AMP) breakdown.

Thecitric acid cycle's intermediary isfumarate.

02

The production of fumarate by the purine nucleotide cycle.

In active muscular tissues, fumarate synthesis via the purine nucleotide cycle is critical for powering the citric acid cycle.

Hence, the citric acid cycle can catabolize the fumarate generated by the purine nucleotide cycle to CO2 .
