YOUR ANSWER : ?

If the ends of the following polysaccharide are pulled, which one would stretch the most?

None of these

Glycogen

Cellulose

Starch

TRUE ANSWER : ?
YOUR ANSWER : ?

Why do some redox reactions in cells result in the transfer of electrons from a reductant with a higher standard redox potential to an oxidant with a lower standard redox potential?

The rules governing oxidation and reduction apply only in vitro, and not in vivo

Electrons always go from reductants with high redox potentials to oxidants with low redox potentials

None of these

Redox potentials are defined under standard conditions, and cellular conditions are typically not standard conditions
