Unit 1
Vocab word:
the factor you change in an experiment
Independent Variable
Vocab Word:
this is the monomer of protein, we have 20 different kinds of these in our body
Amino Acid
Vocab Word:
this is the monomer of nucleic acids
Nucleotide
Carbon forms four large molecules that are essential for the function of life.
Name ALL 4!
Carbohydrates, Proteins, Lipids, and Nucleic Acids.
This macromolecule builds structures, enzymes, and transmits signal messages.
Protein
Vocab Word:
this is a tentative, testable explanation based on observations
Hypothesis
Vocab Word:
a well-tested explanation that unifies observations (does NOT become a law)
Theory
Vocab Word:
the factor you measure in an experiment
Dependent Variable
Vocab Word:
a logical interpretation or assumption based on prior knowledge
Inference (or Infer)
Vocab Word:
describes what happens under certain conditions, but does not explain why
Law
This macromolecule provides quick energy in the body.
Carbohydrates
These are proteins that speed up reactions by lowering the activation energy needed for a chemical reaction to occur in the body.
Enzymes
What element is found in ALL macromolecules?
Carbon (cause it's the ultimate shape shifter!!)
Vocab Word:
a single simple sugar
Monosaccharide
Carbon has valence electrons.
4
Vocab Word:
observations obtained from an experiment; can be numerical, or descriptive
Data
This macromolecule stores and transmits genetic information.
Nucleic Acid
Vocab Word:
this is a small chemical unit that makes up a polymer
Monomer
Vocab Word:
used for comparison in an experiment; does not receive the experimental change
Control Group
What TWO things are always conserved during chemical reactions?
Mass and Energy
Vocab Word:
this is a large, complex molecule that makes up living things
Macrmolecule
Carbon can form covalent bonds with other atoms.
4
This macromolecule stores energy, provides insulation and forms the membranes of cells.
Lipids
Vocab Word:
this is the minimum energy needed to start a chemical reaction
Activation Energy
There are two conditions under which enzymes work best, what are BOTH?
Temperature (98.6 degrees!) and pH properly balanced
