ACTUAL Exam Questions and CORRECT
Answers
What is total body water and how do you calculate it? - CORRECT ANSWER - -It is the
total water in body
-Take the wt of an animal and times it by the decimal version of the corresponding %
What is the average blood volume equal to? - CORRECT ANSWER - 70 mL/kg of bw
What % of blood volume of bw? - CORRECT ANSWER - 6%-8%
What % of intracellular fluid? - CORRECT ANSWER - 40%
What % of extracellular fluid? - CORRECT ANSWER - 20%
What are the two things that make up extracellular fluid and their %? - CORRECT
ANSWER - Interstitial fluid 16% and plasma 4%
What are the major ions in ICF? - CORRECT ANSWER - Cation: Potassium
Anion: proteins and organic phosphates
What are the major ions in ECF? - CORRECT ANSWER - Cation: Na
Anion: Cl and HCO3
What ion is high inside of cell? - CORRECT ANSWER -K
What ion is high outside of cell? - CORRECT ANSWER - Na
,What are the characteristics of cell membrane? - CORRECT ANSWER - - Composed of
lipids and proteins
- Phospholipid and protein component
What are the two protein components in the cell membrane? - CORRECT ANSWER -
Integral and peripheral proteins
Examples of lipid soluble things that can freely move throughout the membrane? - CORRECT
ANSWER - -Oxygen
-Carbon dioxide
-Fatty acids
-Steroid Hormones
Examples of non lipid soluble that can not move freely? - CORRECT ANSWER --
Proteins
-Ions
-Glucose
What are composed of lipids and proteins? - CORRECT ANSWER - -Phospholipids
-Cholesterol
-Glycolipids
What are the components of phospholipids? - CORRECT ANSWER - Glycerol backbone
and fatty acid tails make amphipathic, this helps to forms lipid bilayer
What are integral proteins? - CORRECT ANSWER - They completely span the membrane
What are peripheral proteins? - CORRECT ANSWER - Loosely attached by electrostatic
, How does transport occur across the cell? - CORRECT ANSWER - -Down an
electrochemical gradient
-Against an electrochemical gradient
-Simple diffusion in not carrier mediated
What does down an electrochemical gradient mean? - CORRECT ANSWER - -Simple or
facilitated diffusion
-no input of energy
What does against an electrochemical gradient mean? - CORRECT ANSWER - -Primary
transport (direct input of energy)
-secondary transport (indirect input of energy)
What are the features of carrier mediated transport? - CORRECT ANSWER - Saturation,
Stereospecificity, and competition
What is saturation? - CORRECT ANSWER - Carrier proteins have limited number of bind
sites, which means highest at lower solute concentrations
What is stereospecificity? - CORRECT ANSWER - Binding sites for solute on carrier
proteins are specific
What is competition? - CORRECT ANSWER - Carriers may recognize and bind
chemically-related solutes
What are the factors that contribute to the rate of simple diffusion? - CORRECT
ANSWER - 1. Concentration gradient
2. Partition coefficient
3. Diffusion coefficient
