background image What is the goal of science vs technology? a. Goal of science is the pursuit of knowledge for its own sake while the 
goal of technology is to create products that solve problems and 
improve human life
Which source of scientific information is the most accurate? a. Primary literature Chapter 2 1.  What is matter?  Anything that has mass and takes up space; composed of  elements 2. What is an element?  Cannot be broken down to a simpler form 3. Where are protons, neutrons, and electrons located? What is the charge of 
each? 
Located in an atom a. Protons­ positive; determines element
b. Neutrons­ no charge; determine isotope
c. Electrons­ negative; participate in chemical reactions (outer shell 
electrons determine chemical behavior) d. Nucleus­ consists of neutrons and protons 4. What 4 elements of the 92 naturally occurring elements make up 96% of the 
human body?
a. Carbon

type.
a. Covalent bond­ form when atoms share electrons; examples­  hydrogen, water, oxygen b. Ionic bond­ attractive force between oppositely charged ions; positive  when it loses electrons, negative when it gains electrons; example­ 
NaCl
c. Hydrogen bond­ form between polar molecules; weak forces between  water molecules
background image 7. Why is water a polar molecule?  The electrons of the covalent bonds are not  shared equally between oxygen and hydrogen. 8. Name 5 properties of water. a. Cohesion
b. Moderate temperature (resist change); Regulates body temp.
c. Less dense as ice
d. Solvent
e. Dissociation of water molecules
9. What does the pH scale measure?  Measures the hydrogen ion concentration  in a solution 10. What is the pH range for an acid and a base? What pH is considered neutral? a. 0 to anything below 7 i. Acid < 7 ii. Neutral =7 iii. Basic > 7 11.  What is the function of a buffer?  Minimize pH change and maintain stable  pH in body fluids 12.  What is a hydrolysis reaction?  Adds the equivalent of a water molecule to  break apart macromolecules and releases energy. 13.  What is a dehydration reaction?  Removes equivalent of a water molecule to  link molecular energy and requires energy. 14.  What are the 4 basic macromolecules? a.  Carbohydrates
b. Lipids
c. Proteins
d. Nucleic Acids
15.  What are the characteristics and properties of each macromolecule? (SEE
