If you will give me every bit of your
attention these next 6 days and do the
work I ask you to, you will be prepared
for the EOC. You can decide now that it
is worth the effort, no matter what you
have done the last 6 6weeks.
 So “put on your thinking caps” 


Biochemistry and scientific method
› Handout supplement material for scientific
method, microscope and graphs
› Pass out spark charts
› Have them highlight what I have highlighted
on my key – these are areas to revisit
› Take down the following notes, study them
and use them to help answer the practice
questions
Monomer- is a smaller unit
 Polymer – is the larger unit made of a
bunch of smaller units.

› Monomer- just one bead
› Polymer- two or more beads placed on a
string to make a bracelet.
Carbon cmpd:
Monomer:
Polymer:
Carbohydrate
C:H:O 1:2:1 ratio
monosaccharide
polysaccharide
Lipid
C:H:O not 1:2:1
None
lipid
Protein
C:H:O:N
Amino acid
Protein
Nucleic Acid
C:H:O:N:P
Nucleotide
Nucleic acid
› Remember CHO, CHO, CHON, CHONP

Nucleotide structure
› Sugar
› Phosphate
› Nitrogen base

Enzymes are proteins that speed up a
chemical reaction by lowering the
activation energy
› Endergonic- energy is released or lost
› Exergonic- energy absorbed or used
Independent variable- variable
changed on purpose, the one
manipulated – the if part of the
hypothesis
 Dependent variable- variable that
changes in response, the one measuredthe then part of the hypothesis

› Eating better will make me healthier.
› Change to if, then… If I eat better, then I will
be healthier.
› Independent: eat better
› Dependent: amount of health
