________ reaction.
synthesis
Which of the following is chemically inert (unreactive)?
neon(atomic number 10)
The genetic information is coded in DNA by the
sequence of nucleotides
Which of the following does NOT describe enzymes?
Enzymes work by raising the energy of activation
Which of the following is the major positive ion outside cells?
sodium
Salts are always ________.
ionic compounds
Phospholipids make up most of the lipid part of the cell membrane. Since
water exists on both outside and inside of the cell, which of the following
phospholipid arrangements make the most sense?
2 back to back phospholipid layers with the polar heads facing out on both sides
Which of the following statements is false?
Larger particles move faster than smaller ones and thus collide more frequently and
more forcefully.
Atom X has 17 protons. How many electrons are in its valence shell (outermost
energy layer)?
7

What structural level is represented by the coiling of the protein chain
backbone into an alpha helix?
secondary structure
With a family history of cardiovascular disease, which toast spread would be
considered the most "heart healthy?"
olive oil
A patient is hyperventilating. The "blowing off" of excess carbon dioxide
causes a decrease in blood H+ concentration. How can the carbonic acid-
bicarbonate buffer system function to correct this imbalance?
CO2+H20<-> H2CO3<->H+ + HCO3-
H2CO3 dissociates to form more H+ and lower pH

one

rate?
time
What is the ratio of fatty acids to glycerol in triglycerides (neutral fats)?
3:1

14 neutrons
Which property of water is demonstrated when we sweat?
high heat of vaporization

impulses?
Na (Sodium)
An atom with 3 electrons in its outermost (valence) shell may have a total of
________ electrons altogether.
13
Which statement about enzymes if false?
enzymes require contact with substrate in order to assume their active form
A chemical reaction in which bonds are broken is usually associated with
The release of energy

salivary amylase is an enzyme produced by the salivary glands that breaks
down carbohydrates. What will happen to this enzyme as it follows the food
into the stomach where the pH drops to 2.5?
the enzyme will denature and become inactive
ATP -> ADP+Pi is an example of a ________ reaction.
decomposition
What is dipole?
polar molecule
Which of the following is a general function of fibrous protein?
structural framework
The chemical symbol 0=0 means
the atoms are double bonded

thermometer ________.
in the armpit
You are asked to draw blood from the median cubital vein. You will search for
this vein in the ________.
anterior side of the elbow
Anatomical position is important because _______________.
it allows a common point of reference for body position to help communicate
anatomical relationships
Anabolic reactions are chemical reactions on the body that build things, make
them bigger or more complex. Catabolic reactions break things down making
them smaller or less complex. If the rate of anabolic reaction in the body is
much faster than the rate of catabolic reactions which of the following
necessary life function will be accomplished?
growth

the vertebral cavity.
heart and lungs; anterior
It is wise to study anatomy alongside with physiology because ________.
physiology is only explainable in terms of the underlying anatomy
