Question

. Arrange the following substances in order of increasing tendency to donate electrons
with reasons:
α –ketoglutarate, Oxaloacetate, O2, NADP+
, Malate

Answer 1

Answer:

From lowest to highest tendency to donate electrons:

NADP+, Oxygen (O2), α–ketoglutarate, Malate, Oxaloacetate

Explanation:

Electron donors are those molecules that can easily lose an electron and are known as reducing agents.

Lower the electronegativity, better the electron donor it is

Oxygen is an oxidizing agent and hence, a strong electron acceptor and not a donor.

NADP+ state for this coenzyme functions as an ideal electron acceptor rather than an electron donor
