  • Front
  • Back
active transport
transport(movement) of substances arcoss a cell membrane that requires energy from the cell.
biogass
a mixture of gasses that can be burned to produce energy.
biomass
organic materials that can be used to produce energy
consumer
any organism that eats food
producer
Organisms such as plants that can make their own food
diffusion
the movement of molecules from an area of high consentration to an area of lower consentration
endocytosis
the process where the cell membrane surrounds and pulls substances into the cell
enzyme
a special protien that speeds up chemical reactions
equalibrium
when molecules spread evenly throughout a space or are approximately equal inside and outside the cell
exocytosis
the process where a cell packages substances inside the cell and spits it out the membrand
fermentation
the process that changes glucose into energy without oxygen
gasohol
a mixture of gasoline and ethanol (ethanol is produced using corn!)
inorganic compound
compounds that do not contain carbon
organic compound
compounds that contain carbon
Living things are organic, they are made of carbon compounds.
metabolism
all of the chemical activities that are necessary for living things to live, grow and reproduce
mixture
the combination of things (substances) where each substance keeps it's own properties
osmosis
the diffusion of water
passive transport
the movement of substances through a membrane that doesn't need any energy from the cell
cell
the smallest living thing or part of a living thing.
C
Carbon
H
Hydrogen
N
Nitrogen
O
Oxygen
P
Phosphorus
S
Sulfur
K
Potassium
Na

glucose
sugar
atom
the smallest unit of matter made of protons, neutrons and electrons
Mg
Magnesium
the charge on an electron
negative
the charge on a proton
positive
the charge on a neutron
neutral
ion
a compound that is held together because one part is negative and the other is positive
solution
a mixture where the substances are equally spread out (distributed) throughout the mixture
Example - choclate milk
suspension
a mixture where the substance are equally spread out (distributed) but they eventually seperate.
Example - whipped cream,air suspended in cream
carbohydrates
1.sugar, starch, celluolse
2.made of C,H,and O
3.broken down by the cell to produce energy
4. found in the membrane
lipids
1.fats, oil, waxes
2.C, H, and O
3. stores large amounts of energy to be released by the cell
4.found in the cell membrane
protein
1.enzymes
2.amino acids, C,H,O and N
3.used for building cell parts
4.found scattered in the cell membrane
nucleic acids
1.DNA and RNA
2.C, H, O, N, P
3.stores important information
4.found in chromosomes, mitochondria, chloroplast and nucleus
impermeable
noting can get through a membrane
selectively permeable
somethings are allowed through the membrane, some things are not
photosynthesis
the process plants use chlorophyll to change
water + carbon dioxide + sunlight into sugar(food) and oxygen
respiration
the process animals use to change food(sugar)and oxygen into energy and carbon dioxide
chloroplast
the organelle in a plant cell that carries out photosynthesis
mitochondria
the place in both plant and animal cells where sugar is converted to energy
lactic acid
an acid that builds up in your muscles because there is not enough oxygen and the body uses fermentation to produce needed energy
