Question

which of following molecules get recycled during photosynthesis?
a) NADPH and ATP
b) CO2 and NADPH
c) ATP and glucose
d) water and glucose

Answer 1

well photosynthesis uses sunlight to split H2O and pass on an electron pair to plastoquinone (photosynthesis II) and to NADP+ -> NADPH (photosynthesis I). Also phosphorylation of ADP to ATP..

idk what they mean by recycling.. it would be H2O and CO2 that they "recycle" if anything.

Answer 2

that was my guess and i have no idea either about the recycling

Answer 3

i would go with B, because they do recycle CO2.. and NADPH is just a cofactor so it does kind of just go back and forth, so it's not a true product

Answer 4

in active transport does it matter more on the size of a molecule or its concetration?

Answer 5

concentration; although big molecules can't get across membranes without active transporters...

Answer 6

well OK. the question is a chart and one answer has that the molecule is large but another molecule is a higher concentration inside the substance

Answer 7

i would go with concentration

Answer 8

active transport is needed if concentration is higher in the place it wants to go than where it is

Answer 9

alright thanks. you were right about all but the one posted here:)

Answer 10

woo wel bio is my major

Answer 11

oh wow. glad youre answering my questions then:) thanks again

Answer 12

no prob! good luck with your studies

Answer 13

thanks you too!

Answer 14

I would go with ADP/ATP and NADP+/NADPH because they stay in the system.

The question is vague though
