Levels of Organization
A collection of molecules needed in large amounts
What is a Macromolecule?
Has a neutral or zero charge
What is a Neutron?
Sharing of e- pairs between atoms
What is a covalent bond?
A reaction that results in the building of bonds
What is anabolism?
Substances that, by definition, contain Carbon and Hydrogen
What are Organic Molecules?
The most basic unit of matter
(for this class)
What is an Atom?
Can be found somewhere in the 'cloud'
What is an Electron?
Bound by attraction of oppositely charged ions
What is an Ionic Bond?
When different Elements bond to form a molecule
What is a compound?
Made up of Carbon, Hydrogen, and Oxygen in a 1:2:1 ratio. Ex: Glucose C6H12O6
What are Carbohydrates?
Two or more atoms held together by chemical bonds
What is a molecule?
The number of this particle determines the atomic number of an element
What are protons?
Bonds where electrons are unequally shared between atoms Ex: Water
What is a Polar Bond?
The most common element in the body. Has 2 valence electrons to form bonds with.
What is Oxygen?
Specific molecule made up of 1 glycerol and 3 fatty acid tails
An example includes the Mitochondria: “The powerhouse of the cell”
What is an Organelle?
Adding the number of Protons + number of Neutrons
What is Atomic Weight?
Attraction between a hydrogen atom which is covalently bound to a more electronegative atom
What is a Hydrogen Bond?
What is a double bond?
This molecule contains the sugar Ribose as part of its strand
What is RNA?
A collection of Organ Systems. Examples include your teacher, a pet, or the trees outside.
What is an Organism?
8
16 O -2
What is an Ion? What is an Oxygen Ion?
Outermost electrons used to form bonds
What are Valence Electrons?
A + B -> AB
Typically requires energy
What is synthesis?
When a protein changes shape due to heat, pH changes, radiation, electricity, or other extreme conditions.
What is denature?
