Question

What are two ways Photosynthesis & Respiration are alike?

What are two ways Photosynthesis & Respiration are different?

Answer 1

I make you a deal: I upload a figure that compare them both, you then answer the question? And sure I supervise if the answers are correct or give some good ideas your teacher might not even know ;). Deal?

Answer 2

deal

Answer 3

Both store energy

Answer 4

You mean that both create ATP? well that is correct

Answer 5

both have CO2 & H2O

Answer 6

Both use internal membranes for the components of the cytochrome system needed to transfer the protons and electrons.

Answer 7

Both don't use CO2. The CO2 is released in TCA mostly which also create the NADH that enter oxidation phosphorylation.

But perhaps you could try this instead: both use electrons, but where do they come from in both systems?

Answer 8

Which one get their electrons from water and which one from NADH? :)

Answer 9

Photosynthesis=water
Respiration=NADH

Answer 10

Perfect. And now a little funny thing it might not say in your textbook:
The thylakoid membrane is permeable for magnesium ions and chloride ions, unlike the inner mitochondria membrane. This get the effect that the proton gradient is almost exclusive chemical in photophosphorylation unlike in oxidation phosphorylation where the membrane is not permeable for the ions and therefor there is both a chemical and electrical contribution. :)

Answer 11

And the last thing: the similarity: Try to move the "membrane-protein-system" up side down on one of them... what happens? :)

Answer 12

okay currently doing that

Answer 13

Found that they put out protons out counter wise each other?

Answer 14

pump out protons*
