BSC2085 MIDTERM UPDATED ACTUAL Questions and
CORRECT Answers
The thumbs are pointing medially All of the following are correct positioning when placing the body in anatomical
position, except when _________ _.
Anterior How is the palmar faced when in anatomical position?
Positive feedback The result or response that enhances the original stimulus, and that the response
is accelerated.
Disease A result of homeostatic imbalance could be _________ _.
Upper limb Where are achromial and brachial located?
Blood clotting when the lining of a blood vessel is injured What is NOT the result of a negative feedback mechanism?
Groin Inguinal is the more medically accurate term for _________ ?
Blood clotting Example of positive feedback mechanism?
The pollex at the most lateral feature Anatomical position is characterized by __________ ?
The calf What does sural refer to?
Manus and pedal The term "digital" can be referred to what to parts of body?
Synthesis What type of chemical reaction always involves atoms or molecules combining to
form a larger, more complex molecule?
High concentration of reagents What would speed up the rate of a chemical reaction?
The rate of chemicals will slow down When a cell is placed in a solution that is more very dilute, water will enter the cell
causing the cell to expand. What will happen to chemical reactions in this
situation?
Proton donors and proton acceptors Buffers tend to prevent dramatic changes in the pH when __________ are added to
the solution.
Hydrogen ions in a solution pH is a concentration unit used to measure the concentration of _________ _.
The chemical reactions will speed up When a person has a fever, what happens to the chemical reactions in the body?
Just as with acidity, temperature can denature proteins Fever is a body defense mechanism that speeds healing by increasing enzyme
actions that are necessary to overcome a pathogen. However, temperature can
also have which negative effect?
, Synthesis reaction Match the following: A + B ---> AB
Movement What general function is likely to be affected the least by a pH denaturation?
The rate of chemical reactions will speed up When a cell is placed in a solution that is more concentrated, water will leave the
cell and the cell will shrink. What will happen to the rate of chemical reactions in
this situation?
Release of energy Catabolic reactions involve _________ _.
Electrons When proteins undergo dehydration, what subatomic particles are rearranged the
most?
Water In biochemistry, and this in the body, the universal solvent is ________ _.
Proteins An acidic solution in and around a cell would have the most immediate effect on
cellular function for which type of organic molecule?
Have more H+ ions than OH- ions Something with a pH of 5 would ________ _.
Ions All electrolytes are _______ _.
pH is an important factor in heath because _______ _. H+ ions can disrupt the hydrogen bonds that hold proteins in the correct shape.
Exchange reaction Match the following: AB + C ---> AC + B
Oxygen What is the most common element in the body?
Chemical reactions would slow down If a cell were to become larger, but not gain or lose any of the chemicals inside,
what would happen to the rate of chemical reactions?
Peripheral protein A protein that is not embedded in the lipid bilayer
Osmotic pressure The force that solutes have to attract water
Hydrostatic pressure The force of a liquid pushing against something
Phospholipid A molecular component of the lipid bilayer of the plasma membrane that
possesses a charged polar "head" and an uncharged "tail".
Signal transduction Proteins in the cell membrane that bind hormones and relay messages into their
interior of the cell preform a function known as
Integral protein A protein that is firmly inserted into the lipid bilayer
Plasma membrane The outer boundary of a human cell is the_________ _.
Exocytosis Active membrane transport process
