What would happen to a normal chemical process in your cells if the shape of the enzyme controlling that process was changed by an environmental process?

If the active side of the enzyme was changed, it means that the substrate will not be complementary to the active side thus the enzyme substrate complex will not form, and the reaction cannot take place, at the rate at which normally it would. It would obviously become slower as the number of successful collisions per unit time decreases

The proton has a positive charge while the neutron has no charge they both make up the nucleus of the atom while the elections have a negative charge and surround the nucleus of the atom. the protons and electrons are used to calculate the atom's mass whereas the neutrons don't affect the mass
