GCU BIO-322 Exam 1 Questions With Complete Solutions
5 types of necrosis (autolysis) Correct Answers -Coagulative
-Liquefactive
-Caseous
-Fat
-Gangrenous
Acidosis Correct Answers H+ binds to proteins with fewer
sites for calcium
Increased calcium blocks sodium channels in nerves and
muscles causing muscle weakness
Acidosis and cardiac contractility Correct Answers decreases
Active transport Correct Answers requires ATP
move molecules too large to diffuse
Acute disease Correct Answers Appears quickly
ADH increased causes Correct Answers Increased distal tubule
permeability, increased reabsorption of water into blood,
decreased urine output
ADH suppressed Correct Answers Distal tubules become less
permeable to water; decrease reabsorption of water; Increase
urine output
,Aldosterone function Correct Answers Increases resorption of
sodium from DCT, leading to increased water retention and
plasma volume (renin-angiotensin-aldosterone system)
Alkalosis Correct Answers Increased neuromuscular activity
positive symptoms
Alkalosis and cardiac contractility Correct Answers increases
up tp pH 7.7
Anemic Hypoxia Correct Answers Oxygen-carrying capacity
of the blood is reduced due to
-anemia
-carbon monoxide poisoning
Anion Gap equation Correct Answers Na - (Cl + HCO3)
Antioxidants Correct Answers Inhibit ROS production or
neutralize ROS
-enzymes, vitamins
Antisense Oligonucleotide Correct Answers a modified strand
of RNA or DNA that binds with a specific molecule of
messenger RNA and prevents it from producing its particular
protein
Used in Cancer treatment
Apoptosis Correct Answers programmed cell death
highly selective
, Ascites Correct Answers accumulation of protein-containing
fluid in the peritoneal space
Portal HTN
Atrophy Correct Answers Decreased cell size
Autosomal dominant Correct Answers only needs one copy of
mutated gene present
Autosomal recessive inheritance Correct Answers Requires
defect of both gene copies
(if both parents are carriers- child has 25% chance)
Brain survival time of no oxygen Correct Answers less than 3
minutes
Caseous necrosis (cheese like) Correct Answers Tb; combo of
coagulative and liquefactive
-cells disintegrate/denature but debris is walled off
Causes of edema Correct Answers increased capillary
hydrostatic pressure
Increased capillary permeability
Decreased colloid osmotic pressure
