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.
The enzyme pectinase speeds up the breakdown of pectin in fruits, producing more juice. It speeds up breakdown of pectin in plant cell walls, thus creating more juice. It is also used in wine making to avoid cloudiness.
