*Protein
30 Food Nutrient Analysis
Lab and Catalase Lab
Adding heat to an enzyme will cause
what to happen?

40 Food Nutrient Analysis
Lab and Catalase Lab
What is IKI an indicator for?
40 Food Nutrient Analysis Lab and
Catalase Lab
*Starch
50 Food Nutrient
Analysis Lab and Catalase
Lab
Upon adding Biuret indicator to a
solution, it turns orange. What is this
an indicator of?
50
Food Nutrient Analysis Lab
and Catalase Lab
*contamination! *the specific color
(orange) change does not indicate
the presence of a protein. Only
lavender indicates the presence of
protein.

Hydrogen bonds .
30
Proteins and Nucleic Acids
What are the monomers of
nucleic acids?
30
Proteins and Nucleic Acids
Nucleotides
(Consist of nitrogen base, sugar, and
phosphate)
40
Proteins and Nucleic Acids
Nucleic acids have a 3D helical
structure.
What makes up the backbone
of a nucleic acid? The middle?
40
Proteins and Nucleic Acids
*backbone- sugar and
phosphate held by
covalent bonds
*middle- nitrogen bases
held by hydrogen bonds
50
Proteins and Nucleic Acids
What is the function of an
enzyme?
50
Proteins and Nucleic Acids
Enzymes speed up chemical reactions by lowering the
activation energy of the reaction.
*they are neither the reactants nor products in a chemical
reaction (they are not used up!)

Q: if both a bear in Yosemite and one in
Alaska fall into the water
which one disolves faster?
A: The one in Alaska because it is
