combination of substances in which the substances keep their properties
MIXTURE
it doesn’t become one, ex. chex mix
compound that contains carbon and hydrogen, usually associated with living things
ORGANIC COMPOUND
key words to remember HAS carbon, found in living things
proteins that regulate nearly all chemical reactions in cells
ENZYMES
controls chemical reactions in cells and make things happen faster
compounds made without carbon
INORGANIC COMPOUNDS
key word WITHOUT carbon
movement of substances through the cell membrane without the input of energy
PASSIVE TRANSPORT
NO ENERGY
random movement of molecules from an area where there is relatively more of them in where there is relatively fewer of them
DIFFUSION
fewer and more in an area
i think of the 67 motion
when the number of molecules is relatively equal in two areas
EQUILIBRIUM
Key word EQUAL
the diffusion of water through a cell membrane
OSMOSIS
key word WATER
think of like oasis because of water
when energy is needed to move materials through a cell membrane
ACTIVE TRANSPORT
NEED ENERGY
taking substances into a cell by surrounding it with the cell membrane, vesicles are formed
ENDOCYTOSIS
TAKE INTO A CELL
contents of a vesicle can be released by a cell, substances go out of the cell
EXOCYTOSIS
GO OUT OF CELL
the total of all chemical reactions in an organism
METABOLISM
process by which plants and many other producers (algae, and cyanobacteria) use light energy to make simple sugars that can be used as food
PHOTOSYNTHESIS
think of plants and light energy
chemical reactions break down food molecules into simpler substances and release the stored energy
CELLULAR RESPIRATION
occurs when cells do not have enough oxygen for respiration to release energy stored in glucose molecules
FERMENTATION
NO OXYGEN
true or false: the cell membrane is permeable where substances can enter and exit through it
TRUE, the cell membrane is selectively permeable meaning it lets only some things in or out, but keeps others out.
substances mixed evenly with other substances
SOLUTION
key word mix evenly into ONE WHOLE
more than one element
COMPOUND
think of compound words that have two words or more to make a new word
organic compounds that store important genetic (coded) information
NUCLEIC ACIDS
1 way to remember is to think of the nucleas when it says genetic info
compounds made up of sugar and starches
CARBOHYDRATES
think of carbs cuz sugar is carbs
organic compounds (contains carbon and hydrogen) that store energy
LIPIDS
don’t mix with water
true or false: consumers can make their own food
FALSE, they CONSUME the food that producers made ex. us HUMANS
true or false: producers cannot make their own food
FALSE, they PRODUCE their own food ex. plants
active transport vs passive transport
active has energy while passive has none
