Plants convert the electromagnetic energy of photons into chemical energy stored in atp molecules. an equivalent of 54 atps are then used to make each glucose molecule in the calvin cycle. when cells break glucose molecules down to smaller molecules like carbon dioxide and water they are only able to create 38 atp molecules. what fundamental scientific principle accounts for the difference in those numbers of atp molecules?

answer: i would say b.

explanation:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

a polar bond is formed when electrons are shared unevenly between atoms
