Answer:

Cells are small to have a larger surface area to volume ratio

Explanation:

Since there is always things moving across the phospholipid bilayer of the cell, there needs to be a large surface area compared to volume. A good analogy that I use is elephants ears. They are huge but super thin to keep a large surface area to volume ratio. This lets heat diffuse from the elephant. Its the same thing with cell, maximizing the efficiency of the phospholipid bilayer.

Which chemical reaction would result in the greatest release of energy? A)ADP + P --> ATP B)ATP + Oxygen --> ADP + P C)Pyr
julsineya [31]

The answer is B)  ATP + oxygen --> ADP + P

Adenosine triphosphate (ATP) is the energy currency stored in every living cell. ATP is a complex molecule which composed of the nucleoside adenosine and a tail of three phosphates. Normally energy is released from the ATP molecule by a reaction that removes one of the phosphate-oxygen groups and becomes adenosine diphosphate (ADP). Thus, ATP converts to ADP to liberate energy. ADP soon after release, it is recharged in the mitochondria and comes out again as ATP.

These nutrients are released into air, soil and water and serve as nutrients for autotrophs. Autotrophs produce their own food from sunlight energy, water and carbon dioxide. Example include green plants; which by the process of photosynthesis produce their own food using carbon dioxide and soil nutrients.
