Qa. answers. what will most likely happen if a toxin causes the hydrogen ion pump to stop moving h+ ions outside the mitochondrial membranes of the bird's cells? /q/which_is_a_role_of_photosystem_i _in_the_light_reactions

The bird will not be able to fly since it will quickly use up its remaining energy. If there is no hydrogen ion buildup, thee will be no ATP ( Adenosine triphosphate ) synthesis.

The role of photosynthesis in the light reaction is to make energy-carrier molecules like NADPH.

it is a

explanation:

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
