Based on appearance alone, which one would you expect to be carrying out respiration at a slower rate, the larger or smaller cell? Explain why. - Answer The larger cell. As a cell expands the amount of surface area relative to the volume of the cell decreases. The larger cell is less active because relative to its volume, its surface area is less than a smaller cell. In contrast, a larger surface area (relative to its volume) allows the metabolic processes to occur faster.
