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
