Here is the answer that you are looking for:
External Regulators<span>. </span>External regulators<span> are also </span>proteins<span>, but they react to stimuli from outside the cell. They direct cells to either speed or slow the cell cycle based upon outside conditions. For example, one </span>protein<span> reacts to molecules on the outside of a neighboring cell.

I hope this helps out for you
The correct answer would be b. the products of cellular respiration are the same as the reactants of photosynthesis. Here are the equations for each:
Photosynthesis:
6CO2 + 6H2O + sunlight --> C6H12O6 + 6O2
OR
6 carbon dioxide + 6 water + sunlight --> glucose + 6 oxygen
Cellular respiration:
C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
OR
glucose + 6 oxygen --> 6 carbon dioxide + 6 water + energy
Notice how the products and reactants are switched? The only difference is that photosynthesis requires sunlight, while cellular respiration produces ATP. Hope this helped! :)
