Scientific method
How many variables does a scientist change in an experiment
1
All living things are made of what
cells
What are the functions of lipids
energy storage; build cell membranes; waterproofing
What is the monomer of Proteins
Amino Acids
How does an enzyme work?
Why might a person revise an experiment they did (name 1 reason)
Data did not support hypothesis
An error occurred
What is homeostasis
ability to keep internal conditions stable in response to environmental changes
What is the function of carbohydrates
Main and quick source of energy
What is the monomer of a carbohydrate
Monosaccarides (ring structure)
What are substrates and products
Substrates=beginning molecule
Products=the molecule(s) made after breaking down the substrate
What do call the variable that you change intentionally and where is it located on a graph
independent variable; x axis
What is metabolism
What is the function of Nucleic Acid
Store Genetic information
What is the monomers of lipids
Glycerol head and fatty acid chains
Why can enzymes only bind with one substrate
The active site of an enzyme has a specific shape (lock and key)
What do call the variable that you measure and where is it located on a graph
dependent; y axis
True or False: In order to be considered living; you must be able to respond to the environment
True
What element must an something organic have
Carbon
What is the monomer of nucleic acids
nucleotides
What happens to enzymes when the pH or the temperature changes too much
Enzymes get denatured and the active site is no longer the right shape to bind to substrate
Why is it important to have a control in an experiment
The control is used as a comparison to the experimental variable
True or False: In order to be considered living; you must be able to move on your own
False
What is a polymer
A large structure made of monomers added together in repetition
What is the purpose of the protein hemoglobin
protein in red blood cells that carries oxygen through the body
What are the four characteristics of enzymes
Proteins
Catalysts
Specific
Reusable
