Biology NC Standard Course of Study
What is it you want students to know and be able
to do at the end of your lesson? Know the
molecules of life. Distinguish organic molecule
from other molecules. Know the characteristics
of organic molecules.
How will you know if they accomplish it?
(Formative Assessment, Summative Assessment,
Student Product?) Students will answer questions
in teams. The questions will come from the
powerpoint CE Review of CHEM LIFE This will be
a formative assessment in which the students
product will be to answer the questions to gain
points for their teams. Teachers will give
feedback on each right or wrong question.
Activity Time Description of Activities
1. Opening 5 minutes 5 minutes Use this opportunity to wait for all students to come into class. Students will be assembled into 3 teams as they walk into the door. The teacher should select the teams.
2. Work Period Teacher Input/ Guided Practice Solo Time/ Pair/Group 55min. (Formative assessment) The activity is on a powerpoint so all students can easily read the directions and answer questions concerning the chemistry of life. Students will be divided into 3 teams (Team A,B, C). Team A will go first. If they answer correctly they get full points (3). If they answer incorrectly, Team B can answer for 1 point, and attempt to answer the next available question.
3. Closing Teach facilitated after each question 55min The teacher will explain each answer after each question.
2
What are Enzymes?
3
ANSWER
Enzymes are proteins which act as biological
catalysts.
4
WHAT IS THE MONOMER CALLED FOR THIS
MOLECULE? Hint That is DNA.
5
ANSWER NUCLEIC ACID
6
WHAT WOULD HAPPEN IF THERE WERE NO ENZYMES IN THE
BODY?
7
ANSWER
Without enzymes, several reactions in cells would
never occur or happen to slowly to be useful.
8
THE ITEMS ON THE LEFT SIDE OF THE ARROW ARE
CALLED THE REACTANTS WHILE THE ITEMS ON THE RIGHT
SIDE OF THE ARROW ARE CALLED THE ____________
2H2 O2 ? 2H2O
9
ANSWER THE ITEMS ON THE RIGHT SIDE ARE CALLED
THE PRODUCTS
10
WHAT IS THE MONOMER FOR A CARBOHYDRATE CALLED?
11
ANSWER MONOSACCHARIDE
12
WHAT IS MEANT BY THE TERM SACCHARIDE?
13
ANSWER SUGAR
14
What is a catalyst?
15
ANSWER
It is a substance that speeds up the rate of a
chemical reaction.
16
What is a substrate?
17
ANSWER
Enzymes bind to molecules called
substrates. These substrates are the reactants
that are catalyzed by the enzyme.
18
(No Transcript)
19
ANSWER
20
The site on the enzyme where the substrates bind
is called the_________
21
ANSWER
The site on the enzyme where the substrates bind
is called the active site.
22
How are enzymes affected by the reactions?
23
ANSWER
Enzymes are NOT changed by the reactions they
catalyze, therefore they are reusable!
24
In what ways can enzymes possibly be affected?
Hint Think about the lab on enzymes. Did the
cooked items you tested react differently than
the fresh items when you added peroxide? Did the
acidic and basic items react?
25
ANSWER
Enzymes can be affected by temperature and
pH. Temperatures outside the correct range can
cause enzymes to break down or change shape. This
break down is called denaturation. Therefore,
enzymes in our body work best at 37C (98.6F)
and at a pH between 6.5 to 7.5. Ex Catalase is
an enzyme that breaks down hydrogen
peroxide. H2O2 ? H2O O2 (gas) A raw potato in
H2O2 gives off O2. The boiled potato give no
bubbles because the enzyme has changed due to
heat.
26
The study of all compounds that contain bonds
between many carbon atoms is called what?
27
ANSWER ORGANIC CHEMISTRY
28
Four groups of organic compounds found in living
things are
29
ANSWER carbohydrates, lipids, nucleic acids,
and proteins
30
DESCRIBE THE PROCESS OF POLYMERIZATION OR TELL
WHAT IT MEANS?
31
ANSWER
MACROMOLECULES JOIN TOGETHER IN A PROCESS CALLED
POLYMERIZATION. SMALLER UNITS CALLED MONOMERS
JOIN TOGETHER TO MAKE POLYMERS.
32
DESCRIBE WHAT A LIPID LOOKS LIKE USING CORRECT
TERMINOLOGY
33
ANSWER
LIPIDS or fatty acids like oils Glycerol
connected to 3 fatty chains
34
WHICH ELEMENTS MAKE UP PROTEINS?
35
ANSWER
PROTEINS- contains Nitrogen as well as the
hydrogens, carbons, and oxygens.
36
THE FOLLOWING ELEMENTS MAKE UP WHAT ORGANIC
MOLECULE? CARBON, OXYGEN, HYDROGEN , NITROGEN,
PHOSPHORUS
37

46
THE LOCK AND KEY MODEL OF ENZYME ACTION
ILLUSTRATES THAT A PARTICULAR ENZYME MOLECULE
DOES WHAT?
47
ANSWER
Each protein has a specific shape, therefore
enzymes bind to substrates based on shape.
