The Pentose Phosphate Pathway

Question 1

This is the pathway in which glucose 6 phosphate is used to produce NADPH, ribose 5-phosphate (a pentose phosphate), and numerous other sugar phosphates.

Answer 1

THE PENTOSE PHOSPHATE PATHWAY

Question 2

What are the TWO STAGES of THE PENTOSE PHOSPHATE PATHWAY?

Answer 2

1. Oxidative stage
2. Non-oxidative stage

Question 3

It involves three steps through which glucose 6- phosphate is converted to ribulose 5- phosphate and CO2.

Answer 3

Oxidative stage

Question 4

In the first step, ribulose 5-phosphate (a ketose) is isomerized to ribose 5-phosphate (an aldose).

Answer 4

Non-oxidative stage
