I believe it is the smaller cell that will breathe at a more active
rate because in order for respiration to occur efficiently and
more actively the surface area to volume ratio is very critical;
also, if the larger surface area is present then the diffusion of
gases occur at a higher rate; so, larger cells will have a smaller
You are observing two cells under the surface to volume ratio and diffusion that will occur at a slower

active rate, the larger or smaller cell? The smaller cell. Cells need to remain relatively small
Explain why. because as a cell expands the amount of surface area
relative to the volume of the cell decreases. The smaller cell
is more active because relative to its volume, its surface area
is larger than a bigger cell. With a larger surface area
(relative to its volume) this allows the metabolic processes to
occur faster.

gastric/stomach ulcers. Gastrin stimulates the secretions of pepsinogens and
hydrochloric acid. Excess amounts would lead to erosion of

Parietal and chief cells are located in the stomach wall and
they secrete gastric juices and mucous, secrete hormones that
regulate digestive activity; also, parietal cells produce HCl in
the stomach; and, chief cells secrete te enzymes pepsinogen,
rennin, and gastric lipase.

Chief cells: secrete pepsinogen. Pepsinogen (a pre-enzyme)
is secreted by the chief cells in the stomach. Hydrochloric
acid converts the inactive pepsinogen (secreted by the chief
cells) into the active enzyme pepsin which begins the
breakdown of proteins.
