BLD 204 EXAM 1 ACTUAL QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS GRADED A++
Composition of the Cell Membrane
-FLUID; not solid
-Phospholipid Bilayer(hydrophilic and hydrophobic ends)
-Cholesterol
-Proteins
-Carbohydrates/Sugars outside cell membrane
Functions of the Cell Membrane
-Protect cell from its surroundings
-Regulates exchange of materials w its surroundings
-Control movement of particles
Mitochondria
Take nutrients from cell, breaks it down & converts it to energy
~ATP~
Lysosomes
digest excess or worn out organelles, food particles, and engulfed viruses
Nucleus
Maintains the integrity of genes and controls activities of the cell by regulating gene
expression
~CONTROL CENTER~
, Endoplasmic Reticulum
transports proteins and other carbohydrates to another organelle
Increase surface area
vital role in synthesis
Golgi Complex
processes and packages macromolecules such as proteins and lipids
Peroxisomes
breakdown fatty acid molecules; absorb nutrients that the cell has acquired
Microtubules
involved in nucleic and cell division, organization of intracellular structure, and
intracellular transport
Microfilaments
work with microtubules to form the structure that allows a cell to hold its shape, move
itself, and move its organelles
Ribosomes
make proteins
Etiology
THE HOW
the cause, injury or problem
Pathology
progression of the disease
Hypertrophy
