- Complete using
your textbook to find answers to the following questions. Next week we will spend going over this
information and answering any questions that come up. Good luck and have fun!
Outline Grading Criteria
- Outline shows a conscientious
effort to be complete and explain the questions posed. Most answers are correct.
- Student shows depth of answers by explaining, defining, and giving
examples where appropriate. If
there is a sentence or less for each question, this grading criteria is not met.
to the student CD, chapter 8, activities and choose D. This is a good review of
enzymes and how they function. Use it to
begin or review when you have finished.
Either way it is good to see a visual of what you are reading about.
- What is an enzyme?
- Why is an enzyme
considered a catalyst? Give two
characteristics of catalysts.
- What is an active site?
- What is a substrate?
- What is a product?
- Describe how enzymes facilitate chemical
reactions. Make a drawing including
the enzyme and substrate, enzyme-substrate complex, and resulting
product. (Label the active site on
All enzymes are catalysts, but not all
catalysts are enzymes. Why? What is the difference between a catalyst and
specific in their action? Explain why or
- Would you expect a fat and a sugar molecule to
be acted upon by the same enzyme?
- Enzymes molecules are organic biomolecules.
To which of the 4 major groups of biomolecules
to they belong?
- How does changing temperature affect the rate of
an enzyme-controlled chemical reaction?
12. How does the
changing of pH affect the rate of an enzyme-controlled chemical reaction? Explain in terms of the tertiary structure of
an enzyme and the role of the tertiary structure in enzyme function.
- How fast do enzymes act?
To review the following concepts, use the student CD,
activity 6A. Don’t forget there are multiple screens for
some of the activities.
14. What is energy?
15. Define the following and give examples:
16. What is the relationship between kinetic energy and
17. Define the 1st and 2nd laws of thermodynamics.
- Use the first two
laws of thermodynamics to explain the following:
- heat is released as
a bald eagle soars over the wetland on campus:
- a runner sweats to
Activity 6B refers to ATP and ADP and how they are related to
each other. On my computer I don’t get a
picture associated with the text for the first screen of the activity, but I do
get a visual for the second screen that is pretty good.
- Make a simple diagram of ATP showing this
- Complete this diagram by showing where “energy”
both leaves and enters this cycle.
ADP + P
the arrow that represents an endergonic reation. Label the
arrow that represents an exergonic reaction. Activity 6C reviews the difference between exergonic and endergonic
reactions (there are several screens to proceed through, but this is a good
- Which type of reaction (exergonic
or endergonic) is spontaneous? Give an example.
- Which type of reaction takes continual energy
input to keep going? Give an
- If a reaction is spontaneous, what does it need
