1. What process is producing the pressure?
(A) The acid is degrading the cells, releasing CO2.
(B) A cellular enzyme is breaking down the hydrogen peroxide and
releasing O2.
(C) Normal cellular respiration is producing CO2.
(D) The acid is breaking down the hydrogen peroxide, releasing both
H2 and O2 gases.
 
2. Based on the data, what was the effect of adding the acid to tube A?
(A) The acid disrupted the cell membranes directly, creating an increase
in cell volume.
(B) The acid degraded the hydrogen peroxide, which, in turn, disrupted
the cell membranes and cell walls as a result of the buildup of pressure
within the cells.
(C) The acid denatured the enzyme responsible for the gas production.
(D) The acid reacted chemically with the gas being produced and removed
it from the gas phase within the tube.
3. What was the effect of adding the acid to tube B?
(A) The acid had no effect on the reactions in tube B.
(B) The acid degraded the glucose present within the tube.
(C) The acid caused the release of nitrogen gas.
(D) The introduction of HCl permitted the cells to produce hydrogen gas
from the hydrogen ions.
4. What purpose does tube C serve in this exercise?
(A) It helps determine the role of glycolysis in the gas production process.
(B) It is present to demonstrate the effect of acid on distilled water.
(C) It is present to demonstrate the effect of cellular processes on gas
production.
(D) It is present to help determine any effect that cellular metabolism has
on the gas production process.

175. The flow of ions across a membrane is best associated with
(A) β barrels.
(B) peripheral membrane proteins.
(C) glycosylated proteins.
(D) active transport.

176. Which of the following is truest concerning the cytoskeleton?
(A) Cytoskeletons are found in eukaryotes with cell walls.
(B) Cytoskeletons are found only in eukaryotes.
(C) Cytoskeletons are found in plant cells.
(D) Cytoskeletons are found in multicellular organisms.
(E) Cytoskeletons are found in eukaryotic as well as some prokaryotic
cells.

177. Which of the following changes to a membrane would increase its
fluidity?
