Name the 4 organic molecules
Carbohydrates
Lipids
Nucleic Acids
Proteins (Enzymes)
Active Site
The specific location where a substrate binds on an enzyme.
What is the difference between Cohesion & Adhesion?
Adhesion - water sticks to other things
Cohesion - water molecules stick together
What are the differences between covalent and Ionic bonds?
- ionic bonds involve the transferring of electrons
- covalent bonds involve sharing electrons
H
Hydrogen
Nucleic Acids are responsible for ......
Carry & Store Genetic info
Catalyst
A substance that lowers the activation energy needed to start a chemical reaction. Although it is important in speeding up a chemical reaction, it does not increase how much product is made, and it does NOT get used up in the reaction.
What is a polar molecule?
Molecules (such as water) that have an unequal distribution of charges. They have oppositely charged regions.
Neutrons and protons are located in the _______
Nucleus
O
Oxygen
What is an enzyme protease?
breaking down proteins into smaller polypeptides or single amino acids, and spurring the formation of new protein products
Nucleotide
Small repeating subunits composed of carbon, hydrogen, nitrogen, oxygen, and phosphorus. Term given to the monomer of a nucleic acid.
Water droplets are on a leaf. This represents what property of water?
Cohesion
Explain Van Der Waals forces
Weak electrostatic attractions between molecules.
P
phosphorus
What are the differences between Saturated and unsaturated fats?
Saturated- a fatty acid tail that contains all single bonds. These lipids tend to be solid at room temperature.
Unsaturated- a fatty acid tail that contains one or more double bonds. These lipids tend to be liquid at room temperature.
Amino Acids
Small compounds that are made of carbon, nitrogen, oxygen, hydrogen, and sometimes sulfur. Term given to the monomers of a protein. ? + ? + ? —> protein
