lol i tried but didnt give me what i wanted
1i) Describe where in the chloroplast the light dependent reaction takes place

Thylakoids

ii) Describe where in the chloroplast the light independent reaction takes place.

Stroma

Suggest why each of the following are present in both chloroplasts and mitochondria :

i) phosphorylase enzymes

To produce ATP for respiration by Oxidative phosphorylation?

ii) ribosomes

Sites of protein synthesis.. to make new organic molecules basically.

But it says why are phosphorylase enzymes present in both mitochondria and chloroplasts - i am asuming it is for a chemical reaciton that happens in both mitochondria and chloroplasts
I'm not sure to be honest.Try reading this:

edit: In both the photosynthesis (light dependant and light independant) and respiration reactions (glycolysis, krebs, oxidative phos) you get phosphorylation of ADP.. probably why phosphorylate enzymes are present.

ADP + P ---> ATP
