Advanced Patho Exam – Questions With SolutionsWhat is the cellular function of metabolic absorption? ✔️Ans - Cells can
take in and use nutrients.
Where is most of a cell's genetic information contained? ✔️Ans -
Nucleolus
Which component of the cell produces hydrogen peroxide (H2O2) by using
oxygen to remove hydrogen atoms from specific substrates in an oxidative
reaction? ✔️Ans - Peroxisomes
Which cell component is capable of cellular autodigestion when it is
released during cell injury? ✔️Ans - Lysosomes
Which cAMP-mediated response is related to antidiuretic hormone?
✔️Ans - Increased retention of water
During which phase of the cell cycle is DNA synthesized? ✔️Ans - S
(S=Synthesis)
What organic compound facilitates transportation across cell membranes
by acting as receptors, transport channels for electrolytes, and enzymes to
drive active pumps? ✔️Ans - Proteins
Understanding the various steps of proteolytic cascades may be useful in
designing drug therapy for which human diseases? ✔️Ans - Autoimmune
and malignant disorders
Which structure prevents water-soluble molecules from entering cells
across the plasma membrane? ✔️Ans - Lipid bilayer

communication to be activated? ✔️Ans - Adenosine monophosphate
(AMP)
Under anaerobic conditions, what process provides energy for the cell?
✔️Ans - Glycolysis
What is the mechanism by which the energy produced from carbohydrates,
proteins, and lipids is transferred to adenosine triphosphate (ATP)? ✔️Ans
- Oxidative phosphorylation
What describes passive transport? ✔️Ans - Being driven by osmosis,
hydrostatic pressure, and diffusion
What is the best example of active transport? ✔️Ans - Movement
requiring the expenditure of metabolic energy
Which method of transport uses transmembrane proteins with receptors
with a high degree of specificity for the substance being transported?
✔️Ans - Mediated
The movement of fluid across the arterial end of capillary membranes into
the interstitial fluid surrounding the capillary is an example of which fluid
movement process? ✔️Ans - Hydrostatic pressure
