Answer:
Lipids
If i were to guess, without any answer choices, I would say that we get out energy from carbohydrates, and we store energy in lipids, so Lipids (being long chains) might have the most energy.
Explanation:
Please tell me if this is wrong, I did not have much to work with without any answer choices, and this was very broad. :)
Acidic rain that can deteriorate limestone bases structures
I am taking this now It says in my course, A. Number of organisms.
Acids and bases determine pH. Acids have pH 0 -7 while bases have pH 7 -14. Enzymes function within a very narrow optimum range of pH.
Different enzymes have different optimum pH values. This is the pH value at which the bonds within them are influenced by H+ and OH- ions in such a way that the shape of their active site is most complementary to the shape of their substrate.
Extreme changes in pH above or below the optimum as caused by strong bases and acids can cause the weak linkages e.g. hydrogen bonds in the enzyme's protein molecules to break permanently resulting in denaturation of the protein and impairing its functions because the enzyme can no longer conform its active site to complement that of its substrate and therefore no reaction can take place.
