Question

I really need help with these 4 questions!

Answer 1

2) ADP is similar to rechargeable batteries because it can be continuously combined with inorganic phosphate to produce ATP which is hydrolysed in any energy requiring process back to ADP which can be recombined with inorganic phosphate to reproduce ATP.
3)ATP is manufactured in the mitochondria.
4) Not sure what a macromolecule is. (I did the old GCSE.)
5) From the electron transport chain when electrons gradually lose energy (from photo-excitation) as they are passed from one electron carrier to another.
