Cards

Term
Hierarchy of Life
Definition
Biosphere (earth), Ecosystem, Community, Population, Organism, Organ System, Organ, Tissue, Cell, Organelle, Molecule, Atom
Term
Sun
Definition
Ultimate source of Energy on our planet
Term
Cell Theory
Definition
1. All living things made up of cells
2. Cells come from other cells
3. Cell is the basic unit of life
Term
3 Main Domains of Life
Definition
1. Eucaryota
2. Bacteria (Prokaryotes)
3. Archaea (Prokaryotes)
(2 and 3 make up kingdom "MONERA")
Term
Most common ELEMENTS in living organisms
TOP 99.9% (TOP 96%)
Definition
CHONCaPKS (CHON)
Term
Goiter is caused by _______ deficiency
Definition
Iodine deficiency
Term
Compound
Definition
Chemical union of 2 or more elements bonded together in a fixed ratio
Term
Atomic Mass
Definition
The mass of a given atom expressed in atomic mass units, amu.  Approximately equal to # protons + # neutrons. For Example: Carbon = 12.001 amu
Term
Atomic Number
Definition
The number of Protons in an atom. For Example: Carbon's atomic # is 6 because it has 6 protons
Term
Isotopes
Definition
Atoms with same # of protons but different # of neutrons (so they'll have different atomic mass units but the same atomic number) For Example: Carbon-12 and Carbon-14 are ISOTOPES
Term
pH
Definition
A measure of how acidic (low #) or basic (higher #) a solution is where 7 is neutral
Term
Acid Rain
Definition
Rain w/ high concentrations SULFUR DIOXIDE and NITROGEN OXIDE put into the atmosphere by burning fossil fuels like oil or coal
Term
Isomer
Definition
2 or more substances w/ same chemical formula but they differ in arrangement of molecules so they will have different properties
Term
Amino Acids
Definition
Building blocks of proteins. There are 20 basic building blocks and each has an amine, a carboxyl group and a central C with an R group attached. (Named according to their R group)
Term
Enzyme
Definition
A special protein that lowers the Energy of Activation for a reaction- so it makes the reaction happen faster (catalyzes the reaction)
Term
Polysaccharide
Definition
Carbohydrate w/ the basic formula (C6 H2 O5)n that is made up of monosaccharides. For Example: Insulin, Starch and Cellulose
Term
Sugar Storage in PLANTS
Definition
Starch
Term
Sugar Storage in Animals
Definition
Glycogen
Term
Chitin
Definition
Material that makes up exoskeletons of crustaceans (arthropods in general) and the cell wall of certain fungi
Term
Arthropod
Definition
Any of numerous invertebrate animals of the phylum Arthropoda, including the insects, crustaceans, arachnids, and myriapods, that are characterized by a chitinous exoskeleton and a segmented body to which jointed appendages are articulated in pairs.
Term
Polypeptide
Definition
Large protein made up of many peptide bonds (joining of AA's)
Term
What Denatures a Protein?
Definition

High Heat

pH changes

Salt Levels

Radioactivity

Term
DNA is made of what 3 things?
Definition

1. Nucleotide Base (A, T, C or G)

2. DeOxyribose (Sugar)

3. Phosphate Group (PO4-)

Term
RNA is made of what 3 things?
Definition

1. Nucleotide Base (A, U, C or G)

2. Ribose (Sugar)

3. Phosphate Group (PO4)2-

Term
Function of Centrioles
Definition
Form the poles of the spindle fibers during cell division
Term
Function of RIBOSOMES
Definition
Protein synthesis- they're found on the RoughER as well as floating freely. There are ribosomes in the nucleolus.
Term
Endomembrane System
Definition

Includes the nuclear envelope, the ER, Golgi Apparatus, lysosomes, vacuoles and the plasma membrane.

 

 Importantly, the endomembrane system does not include the membranes of mitochondria or chloroplasts.

Term
Mitochondria Structure and Function
Definition

ATP producing organelle composed of:

Inner and Outer Membranes

Intermembrane space

Matrix

Crista (folds of the inner membrane)

 

Electron Transport Chain (or Chemiosmosis or Oxidative Phosphorylation) takes place across the double membrane and ATP is produced here.

Term
Chloroplasts
Definition
Organelles in plant cells where photosynthesis takes place.
Term
Thylakoids
Definition
Membrane bound compartments found in chloroplasts where the light dependent reactions of photosynthesis take place. Stack of Thylakoids is called a grannum (plural granna)
Term
ATP
Definition

Term
universal genetic code
Definition

Definition
mRNA sequence:AUG (codes for methonine)
Term
start codon that has been translated to tRNA
Definition
TAC
Term
there are ___ stop codons
Definition
3
Term
when you say "stop codon" or "start codon" you are ALWAYS talking about the _______
Definition
mRNA strand
Term
Anticodons are located on ______
Definition
