You might want to actually write your answers in Word (so you can spell
check them) and then cut-and-paste into the boxes. That way, if the computer
misplaces your work you can just re-paste the answers.
Since we may work on this over more than one day, I will keep track of what
you have done. Feel free to click submit as you work to save your work to the
TAB OR USE THE MOUSE Between the
Answer the questions as best you can. The boxes will expand as you type if you need more space.
(Don't worry if it is a one word answer. The box size is standard.)
Since you will be working in groups, put all the names of the people in the
group in the box. The ideal group size is 2. As an exception I will allow groups
of 3. No groups of 4 or 5. If you work as a group of 3 I expect better answers.
Group sizes above 3 will be penalized in the grading.
You can work on this from home once you have signed up for Successnet.
Open the Explore Life CD in a separate window. (If you need help
with that ask.)
If you have already signed up for SuccessNet, you can access the assignment
that way, and also work from home (or library).
While there are questions on the CD, they provide answers, so I can't grade
their questions. You will get a grade for the answers on this form!

Start with Concept 5.1 The questions proceed with the disk. Do all the
activities. You also have to do the "Closer Look" Answer my questions.
Question 1: What makes something an organic molecule? How
many distinct covalent bonds can oxygen make? How many distinct covalent bonds
can carbon make?
What molecule is produced as polymers are formed? Contrast dehydration
synthesis and hydrolysis?
Question 3: Compare glycogen and starch. What do they have in
common? How are they different?
Question 4: In
practical terms give one example of a consequence of oil and water being
immiscible (not mixing) (think kitchen).
5. Animal fat is rich in what kind of fatty acids, saturated or unsaturated?
6 How different are estradiol, testosterone and DHEA? Why do you think they
have such different effects?
7. What process combines amino acids in making a polypeptide? What is meant by
the "R" group? How many kinds of "R" groups are there in
8: (Make sure you do the Closer Look).
are the two kinds of secondary structure in proteins?
(in your own words) the 4 levels of protein structure (primary, secondary,
would be the effect of changing one amino acid in the sequence on the primary,
secondary, tertiary and quaternary structures?
9. For the enzyme in the simulation, what is the optimum temperature? Above are
several graphs. Which graph best represents the effect of temperature on enzyme
activity? What do you think the optimum temperature would be for human digestive
enzymes (extra point for using Celsius!)?
