Question

Hey.

The breakdown of foodstuffs to simple molecules in cells:

a) is an oxidative process
b) is a reductive process
c) takes place only in mitochondria
d) consumes NADPH

I would say it is a, because requires oxygen (for example C6H1206+6O2->6CO2+6H20, am I right?

Answer 1

Oh, I am totally incorrect, I guess, because oxidative process is a loss of electrons, and reductive process is a gain of electrons. I would't say it is c), because organisms like bacterias doesn't have mitochondrias, so the answer maybe is D? (because NADPH takes place in ATP synthesis)

Answer 2

@ganeshie8 please, take a look

Answer 3

Answer 4

I think it is totally A.

Answer 5

oh, really? Can you explain why?

Answer 6

Well you explained it quite well, and I went and looked it up on the internet and I found that "oxidative process" was the one that most people had chosen so. But your explanation for it was spot on.

Answer 7

Hm, okay, thank you. But still I am confused by all this electrons loss/gain part. Do you know anyting about it?

Answer 8

It's not really my strong-suit.

Answer 9

Thanks;) Maybe I should ask this in Chemistry section? (because it is from Biochemistry module)?

Answer 10

Yeah! I definitely think someone could give a better explanation over there!
