the abdominal cavity. stomach, intestines, spleen and liver
True or False? a. True
a. Cellular respiration occurs b. True
in the mitochondria. (T or F) c. False
b. The purpose of cellular d. False
respiration is to produce ATP. e. False
(T or F)
c. Integral proteins are only
found on the inner surface of
a cell membrane. (T or F)
d. Endocytosis is the process
that occurs to eject
biomacromolecules from the
cell. (T or F)
e. Pinocytosis uses a signaling
molecule from another cell,
binding to the cell membrane
to bring about changes within
the cell proteins. (T or F)

smaller cell? Explain why. occur at a slower rate creating a less
active respiration; and, on the other hand
smaller cells will have a larger surface
area to volume ratio and an improved
diffusion rate, so the higher rate and
more active respiration.
The smaller cell. Cells need to remain
relatively small 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.

Explain why someone who has Hypergastrinemia leads to excess
hypergastrinemia (excessive secretion of the gastrin hormone, which
secretion of gastrin) might induces excess secretion of hydrochloric
develop gastric/stomach acid in the stomach; and, the excess acid
ulcers. then acts as a protective mucousa layer
causing disruption that can lead to those
ulcers.
Gastrin stimulates the secretions of
pepsinogens and hydrochloric acid.
Excess amounts would lead to erosion
of the stomach lining.
