Biology Study Guide Module 5
1. Define the following terms
a. Matter – anything that has mass and takes up space.
b. Model – an explanation or representation of something that cannot be seen.
c. Element – a collection of atoms that all have the same number of protons
d. Molecules – chemicals that result from atoms linking together.
e. Physical change – a change that affects the appearance but not the chemical makeup of a substance
f. Chemical change – a change that alters the makeup of the elements or molecules of a substance.
g. Phase – one of three forms – solid, liquid, or gas – which every substance is capable of attaining.
h. Diffusion – the random motion of molecules from an area of high concentration to an area of low concentration.
i. Concentration – a measurement of how much solute exists within a certain volume of solvent.
j. Semipermeable membrane – a membrane that allows some molecules to pass through but does not allow other molecules to pass through.
k. Osmosis - the tendency of a solvent to travel across a semipermeable membrane into areas of higher solute concentration.
l. Catalyst- a substance that alters the speed of a chemical reaction but is not used up in the process.
m. Organic molecule – a molecule that contains only carbon and any of the following: hydrogen, oxygen, nitrogen, sulfur, and/or phosphorous
n. Biosynthesis – the process by which living organisms produce larger molecules from smaller ones.
o. Isomers – two different molecules that have the same chemical formula
p. Monosaccharides –simple carbohydrates that contain 3 to 10 carbon atoms.
q. Disaccharides – carbohydrates that are made up of two monosaccharides
r. Polysaccharides – carbohydrates that are made up of more than two monosaccharides.
s. Dehydration reaction – a chemical reaction in which molecules combine by removing water.
t. Hydrolysis – breaking down complex molecules by the chemical addition of water.
u. Hydrophobic – lacking any affinity to water.
v. Saturated fat – a lipid made from fatty acids that have no double bonds between carbon atoms.
w. Unsaturated fat – a lipid made from fatty acids that have at least one double bond between carbon atoms.
x. Peptide bond – a bond that links amino acids together in a protein.
y. Hydrogen bond – a strong attraction between hydrogen atoms and certain other atoms (usually nitrogen or oxygen) in specific molecules.
2. Describe where the protons, neutrons, and electrons are in an atom. Protons and neutrons are in the center, and electrons orbit around them.
3. What determines the vast majority of characteristics in an atom? The number of electrons (and protons)
4. What does the number after an atom’s name signify? The sum of protons and neutrons.
5. What is the difference between an element and an atom? An element has all atoms that have the same number of protons. An atom is a single thing of protons, neutrons, and electrons.
6. How many electrons are there in an atom that has 32 protons? 32
7. How many atoms (total) are there in a molecule of C3H8O? What atoms are present and how many of each atom? 3 carbon, 8 hydrogen, and 1 oxygen. = 12
8. Identify the following as an atom, element, or molecule.
a. H2CO3 – molecule (several atoms linked together)
b. Nitrogen-14 – Atom (because it specifies the number of neutrons and protons)
c. P – element (because it by itself doesn’t specify the number of neutrons and protons)
9. If you add energy to the molecules of a liquid, will it turn into a gas or a solid? A gas.
10. A chemist wants to study diffusion. Should a semipermeable membrane be used? No. (Semipermeable membranes allow only solvent molecules to pass. For diffusion to work, both solute and solvent must be able to travel across the membrane).
11. Two solutions of different solute concentration are separated by a membrane. After a while, the water levels of the two solutions change. Has osmosis or diffusion taken place? What kind of membrane is being used? Semipermeable membrane. Osmosis. (Since the water levels, changed, that means solvent traveled from one side of the membrane to the other, but solute did not).
12. Consider the following chemical reaction: N2 + 3H2 = 2NH3
a. What are the reactants? (N2 + H2)
b. What are the products? (NH3)
c. How many molecules of H2 are used in the reaction? (3)
13. What is the chemical equation for photosynthesis? What 4 things are necessary for a plant to carry out photosynthesis? (6CO2 + 6H2O -> C6H12O6 + 6O2)
14. Other than using a catalyst, how can a reaction be sped up? Add more heat.
15. Which of the following is a carbohydrate?
a. NH3
b. CO2
c. C2H4O
d. C5H10O5 – carbs can only have carbon, hydrogen, and oxygen and no other elements. They must have twice as many H’s as O’s.
e. C3H8O3
16. What kind of reaction is used for building disaccharides, polysaccharides, fats, and proteins? (Dehydration reactions build up these molecules, and hydrolysis reactions can break them down, providing the proper enzymes exist)
17. Which of the following is an acid? C. Must have
O
l l
- C – OH
18. Describe the pH scale and what it means. The pH scale measures acidity or alkalinity of a solution. 7 is neutral. Lower than 7 is acidic, and higher is alkaline. (the lower the pH the more acidic, and the higher the pH the more alkaline)
19. What are the basic building blocks of proteins, lipids, and polysaccharides? Amino acids= proteins. (Amino acids link together to make proteins, fatty acids link to glycerol to make lipids, and monosaccharides link together to make polysaccharides).
20. If two proteins contain the same type and number of amino acids, but the order in which they link up is different, are the properties of the two proteins the same? These won’t have the same properties. (the number and type but also the order of the amino acids determines a protein’s structure and function)
21. What are enzymes, and for what purpose are they usually used? Enzymes are special proteins used as catalysts.
22. What is the “lock and key” theory of enzyme action? (The “lock and key” theory of enzyme action says that an enzyme has an active site that is shaped especially for the molecule that it must work on. The action that the enzyme takes cannot happen until the molecule attaches to the active site. Since the active site is shaped for a specific molecule, such an enzyme cannot work on other molecules, unless it happens to have the same shape.
23. What are the basic parts of a nucleotide? Phosphate group, sugar, and the base.
24. How does DNA store information? DNA stores information as a sequence of nucleotide bases. (Much like all of the English language can be stored as a sequence of dots in Morse code.
25. What holds the two helixes in a DNA molecule together? Hydrogen bonds (between the nucleotide bases)

Is it worth it can you even hear me
Standing with your spotlight on me
Not enough to feed the hungry
I'm tired and I felt it for awhile now
In this sea of lonely
The taste of ink is getting old
It's four o' clock in the f****** morning
Each day gets more and more like the last day
Still I can see it coming
While I'm standing in the river drowning
This could be my chance to break out
This could be my chance to say goodbye
At last it's finally over
Couldn't take this town much longer
Being half dead wasn't what I planned to be
Now I'm ready to be free
So here I am it's in my hands
And I'll savor every moment of this
So here I am alive at last
And I'll savor every moment of this
Won't you think I'm pretty
When I'm standing top the bright lit city
And I'll take your hand and pick you up
And keep you there so you can see it
As long as you're alive and care
I promise I will take you there
We'll drink and dance the night away
We'll drink and dance the night away
^Uh, part of the lyrics to "The Taste of Ink" by The Used... I was getting lyrics for a bunch of my songs.
