Term
osmosis
Definition
movement of water molecules from an area of high concentration to low concentration
Term
diffusion
Definition
movement of molecules from an area of high concentration to low concentration
Term
active transport
Definition
movement of molecules against their concentration gradient from an area of LOW concentration to HIGH Concentration.

THIS REQUIRES ENERGY!
Term
hydrophilic
Definition
water loving (phosphate heads of the phospholipid molecule)
Term
hydrophobic
Definition
water hating/fearing (fatty acid chains of the phospholipid molecule)
Term
bilayer
Definition
two layers
Term
phospholipid
Definition
the primary molecule of the cell membrane (made up of a phosphate head and fatty acid tails)
Term
hypertonic
Definition
a solution that has not a lot of molecules in it in comparison to the concentration of water.
(hyper= above)

CAUSES CELLS TO SHRINK!
Term
hypotonic
Definition
a solution that has a lot of molecules in it in comparison to the concentration of water.
(hypo= below)

CAUSES CELLS TO SWELL!
Term
isotonic
Definition
a solution that has the same concentration in comparison to the inside of the cell.

NO NET MOVEMENT OR CHANGE IN SIZE!
Term
photosynthesis
Definition
the process where sunlight creates sugars in plants

OCCURS IN THE CHLOROPLAST
Term
cellular respiration
Definition
process where cells turn glucose and oxygen into usable energy

OCCURS IN THE MITOCHONDRIA
Term
INPUTS FOR PHOTOSYNTHESIS
Definition
Carbon dioxide (CO2), WATER, Light
Term
OUTPUTS OF PHOTOSYNTHESIS
Definition
Glucose (C6H1206) and OXYGEN (O2)
Term
INPUTS FOR CELL RESPIRATION
Definition
Glucose (C6H1206) and OXYGEN (O2)
Term
OUTPUTS OF CELL RESPIRATION
Definition
Carbon dioxide (CO2), WATER, ENERGY (ATP)
Term
Mitochondria
Definition
Makes energy for the cell by doing cell respiration
Term
Chloroplast
Definition
Part of the plant cell that does photoysnthesis
Term
Protein monomer
Definition
amino acids
Term
Carbohydrate monomer
Definition
monosaccharide
Term
Lipid monomer(s)
Definition
glycerol molecule + 3 fatty acid chains
Term
Nucleic acid monomer
Definition
nucleotides
(phosphate + sugar + nitrogen base)
Term
function of proteins
Definition
most day to day functions of cells
to build structures
to speed up chemical reactions
immune system functions
Term
function of carbohydrates
Definition
quick energy source

ex. glucose, starch
Term
function of lipids
Definition
long term energy storage

ex. fats
Term
function of nucleic acids
Definition
carry important messages and information

ex. DNA and RNA
Term
enzyme
Definition
proteins that speed up chemical reactions
Term
activation energy
Definition
the amount of energy required to get a reaction to occur
Term
catalyst
Definition
anything that speeds up a reaction or occurrence.
Term
substrate
Definition
the substance that is acted upon by an enzyme
Term
active site
Definition
the region of the enzyme that activates it use, this is where the substrate fits like a lock and key.
Term
semi-permeable
Definition
the cell membrane is semi-permeable because some things are allowed through and other things aren't.
Term
DNA monomer
Definition
nucleotide
Term
3 parts of a nucleotide
Definition
phosphate group, deoxyribose sugar, and a nitrogen base
Term
DNA Base Pair Rules
Definition
A pairs with T
C pairs with G
Term
RNA Base Pair rules (for transcription)
Definition
A pairs with U instead of T
C pairs with G
Term
transcription
Definition
the copying of the DNA code onto a strand of mRNA (in the nucleus)
Term
translation
Definition
when mRNA transfers the message from DNA to the ribosome & tRNA to assemble amino acids forming a protein
Term
double helix
Definition
the shape of a DNA molecule
