Diffusion
|
the movement of particles from an area of higher concentration to lower concentration
|
|
Selectively Permable Membrane
|
•only allows certain particles to pass through
•Diffusion can also happen across a selectively permable membrane |
|
Osmosis
|
•the diffusion of water across a selectively permable membrane
•moves from high to low water concentration |
|
Osmosis in Cells
|
•contains lots of sugars, proteins,etc.
•keep gain water of losering water until con. inside same as outside. |
|
Active Transport
|
•moves molecules form low to high con.
•REQUIRES ENERGY |
|
Passive Transport
|
•Diffusion&Osmosis
•High to low con. •no energy required •small and uncharged molecules |
|
Active Transport
|
•low to high con.
•energy required •small or large molecules •charged or uncharged molecules |
|
Facilitated Diffusion
|
•high to low con.
•no energy required •large and charged molecules •use protein channel in cell membrane |
|
Endocytosis/Exocytosis
|
•energy required
•very large molecules •cell membrane •endocytosis - brings in •exocytosis- releases out |
|
BTB
|
a chemical that detect Carbon Dioxide
|
|
Energy
|
•get from food
•breaks down food into food molecules •releases ATP |
|
Cellular Respiration
|
•required oxygen
•happens in mitochondria •C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (as ATP) |
|
Fermentation
|
•no oxygen required
•partically breaks down food •Reactants- glucose •Products- Carbon Dioxide+Lactic Acid+ATP |
|
Photosynthesis
|
•happens in chloroplast
•capture light energy make their own food •extra glucose is stored as starch |
|
Photosynthesis work
|
•chlorophyll captures light
•6 CO2(gas) + 12 H2O(liquid) + light energy → C6H12O6(aqueous) + 6 O2(gas) + 6 H2O(liquid) |
