The three subatomic particles that make up an atom
What are protons, neutrons, and electrons
An attractive force that holds molecules of the same substance together
What is cohesion?
A group of organic molecules that are hydrophobic
what is a lipid
Helix coils around proteins to form chromosomes
What is DNA
What is a substrate
The number of protons in an atom's nucleus
What is the atomic numbe
An attractive force that holds molecules of different substances together.
What is adhesion
what are proteins, lipids, carbohydrates and nucleic acids
What is RNA
A substance that alters the speed of a chemical reaction without being consumed or changed in the process.
What is a catalyst
A chemical substance that results when two or more atoms join together chemically
What is a molecule
Any substance in which other substances are dissolved
What is a solvent
The difference between a saturated and unsaturated fatty acid molecule
What is a double carbon bond
The three basic parts of a nucleotide
What are the phosphate group, the sugar and the base
The process in which the normal 3D shape of a protein is destroyed, usually due to high heat or extreme pH.
What is denaturation
Calcium has an atomic number of 20 and an atomic weight of 40. What is the breakdown of subatomic particles
The property of water that allows small insects to walk on its surface without sinking.
What is surface tension (caused by hydrogen bonding/cohesion)
These large macromolecules are made of monosaccharide subunits and serve as a primary energy source for living organisms
what are carbohydrates
The part of the nucleotide that is responsible for the way DNA stores its information
What is the nucleotide base?
The specific region on an enzyme where the substrate binds during a chemical reaction.
What is an active site
An atom that has gained or lost electrons, giving it a net electrical charge.
what is an ion
the ability of solid water (due to the crystal structure from hydrogen bonds as water freezes) to float above liquid water
what is density
20 amino acids only vary in
What is their R group (side group)
Holds the two helixes in DNA together
What is hydrogen bonding
How an enzyme affects the activation energy of a chemical reaction.
