A type of passive transport in cell where molecules move from areas where that are more of them to areas where there is less of them
Active Transport Hint: Takes Energy
Energy requiring process that transports proteins through a cell membrane
Osmosis Hint: Passive Transport
Passive transport that occurs when water diffuses through a cell membrane
Photosynthesis Hint: light
Process where plants and other producers use light to produce sugar for energy
Enzyme
a type of protein that regulates nearly all cell activities
Endocytosis
process by which a cell takes in a substance by surrounding it with a cell membrane
Metabolism
the total of all chemical reactions in an organism
Exocytosis
process by which vessicles release their contents outside the cell
Passisve Transport
movement of substances through a cell membrane without the use of cellular energy
Mixture
a combination of substances in which the individual substances do not change
Respiration
process by which consumers and producers release stored energy from food molecules
Organic Compound
compounds that always contain hydrogen and carbon
Inorganic Compound
compound such as h2o, that is made from elements other than carbon and whose atoms usually can be arranged in only one structure
Fermantation
process by which oxygen - lacking and some one celled organisms release small amounts of energy from glucose molecules and produce wastes such as alchonal, carbon dioxide, and lactic acid
Equilibrium
occurs when molecules of a substance are spread evenly throughout another substance
Matter
anything that takes up space and has mass
Atoms
protons, electrons, neutrons
Element
substance made up of one type of atom
Compound
Ionic compounds, molecular compounds
Molecular
when atoms share the outermost electrons
Ionic
electric charged atom
Ionic compound
formed when opposite charged atoms affect each other
