Academic Biology – Study Guide for Biochemistry and Macromolecules Assessment
I can describe and analyze the properties of the elements essential to life: CHNOPS
1.
2.
3.
4.
Element names.
Valence electrons and bonding characteristics of each element.
Where the elements can be found in the body.
Why the elements are essential in the human body.
I can distinguish between the four main classifications of macromolecules based on their structure and
properties.
1.

5.
6.
Identify and describe the 4 main classifications of macromolecules.
Function of each macromolecule in the body.
In what foods do we find each type of macromolecule?
The monomer for each macromolecule and examples
The polymer for each macromolecule and examples.
The general structure of each type of macromolecule – be able to distinguish the different
macromolecules based on structure.
I can investigate for the presence of monosaccharides, starches, and proteins in foods by identifying positive
colorimetric reactions with indicator tests.
1. The indicators used to identify monosaccharides, starches, and proteins
2. The colors present in a positive test for each indicator.
3. Be able to apply what you learned during the labs to a real world scenario.
I can analyze scenarios to identify enzymes and substrates; and assess possible causes for enzyme
denaturation.
1. The purpose and function of enzymes.
2. How enzymes relate to catalysts and how energy is influenced.
3. Enzymes are what type of macromolecule?
4. Factors that contribute to enzyme denaturation
I can apply biochemistry vocabulary words to real world situations.
1. Like your vocab quizzes, be able to apply your 22 vocabulary words, not just memorize the
definitions.
2. Review your quizzes.

7. What is the difference between reactants and products in a chemical reaction?
Reactants go into to the chemical reaction and products are what come out.

Function(s)
To provide and store energy and
help with structure
Provide long term energy storage
and send messages.
Facilitated chemical Reactions,
immune response, Protect the body
Store and transmit Genetic
Information
9. What is the difference between a condensation reaction and a hydrolysis reaction?
Condensation reaction loses a molecule of water to link monomers together and a hydrolysis uses
water to break polymers into monomers.
10. What is an enzyme substrate complex? Explain the Lock and Key model?
When an enzyme and substrate bind together at an active site.
11. How can enzymes become denatured?
When the temperature or pH change.
12. Why is an enzyme referred to as a catalyst?
Because it speeds up chemical reactions.
