Question

Oxidation of 3 molecules of glucose by pentose phosphate pathway results in the production of ____________

(a) 3 molecules of pentose, 6 molecules of NADPH and 3 molecules of CO2

(b) 4 molecules of pentose, 6 molecules of NADPH and 3 molecules of CO2

(c) 4 molecules of pentose, 3 molecules of NADPH and 3 molecules of CO2

(d) 3 molecules of pentose, 4 molecules of NADPH and 3 molecules of CO2

The question was posed to me by my school principal while I was bunking the class.

My question comes from Advanced Questions and Answers in chapter Regulation of Gene Expression and Miscellaneous of Biochemistry

Answer 1

Correct option is (a) 3 molecules of pentose, 6 molecules of NADPH and 3 molecules of CO2

To explain: Glucose 6-phosphate + 2NADP^+ + H2O → ribose 5-phosphate + CO2 + 2NADPH + 2H^+.
