a) Why is it significant that ions being transported across a cell membrane be shielded from the interior of the lipid bilayer?
b) Why is photosynthesis referred to as a biochemical pathway?
Ans)
a) The interior of the lipid bilayer is nonpolar and thus would repel ions, which are attracted to polar environments.
b) Photosynthesis includes many chemical reactions linked like that the product of one reaction is consumed in the next reaction.
