What are the monomers of Lipids?
Fatty acids and Glycerols
What is a molecule that has "electrically" charged areas?
Polar molecule
What type of macromolecule is an enzyme?
protein
What is Activation energy?
The energy needed to start the chemical reactions.
What are the monomers of Proteins
Amino acids
What are the functions of Lipids?
Long-term source of energy, provides insulation, provides protection to organs, make up cell membrane
What is the difference between cohesion & adhesion?
cohesion: an attraction between molecules of the same substance
adhesion: a force of attraction between different kinds of molecules
How does an enzyme act as a catalyst?
It speeds up a chemical reaction.
What 2 things can denature an enzyme?
temperature and pH
What is the main function of carbohydrates?
Short-term energy source
What are the monomers of Nucleic acids?
Nucleotides
Water rising in a tube is an example of what property?
Capillary action
Can a single enzyme be used over and over?
Yes!
Define active site.
The place on an enzyme where the substrate binds.
What are the monomers of carbohydrates?
Monosaccharide
What is the main function of Nucleic acid?
Store genetic information, transfer and carry genetic information, hold instructions to make proteins
What property of water helps to moderate the earth's temperature?
High Specific Heat
Why is an enzyme complex always compared to a "lock and key"?
There is only one type of key that will fit into a lock, as there is only one type of substrate that will fit into the active site of an enzyme.
What happens to Activation Energy with an enzyme is present?
It decreases
What are the polymers of carbohydrates?
Cellulose, Starch, Glycogen
What are the functions of proteins?
Build bones, muscles, tissues; fight infections(antibodies); enzymes
Which property of water allows a water strider to walk on the surface of the water?
Surface Tension (or Cohesion)
What do enzymes do?
Speed up the rate of chemical reactions by lowering the activation energy.
The enzyme in the potato that breaks down Hydrogen Peroxide is called?
catalase
