Atomic

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

Energy requiring process that transports proteins through a cell membrane

Passive transport that occurs when water diffuses through a cell membrane

Process where plants and other producers use light to produce sugar for energy

a type of protein that regulates nearly all cell activities

process by which a cell takes in a substance by surrounding it with a cell membrane

the total of all chemical reactions in an organism

process by which vessicles release their contents outside the cell

movement of substances through a cell membrane without the use of cellular energy

a combination of substances in which the individual substances do not change

process by which consumers and producers release stored energy from food molecules

compounds that always contain hydrogen and carbon

compound such as h2o, that is made from elements other than carbon and whose atoms usually can be arranged in only one structure

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

occurs when molecules of a substance are spread evenly throughout another substance

anything that takes up space and has mass

protons, electrons, neutrons

substance made up of one type of atom

Ionic compounds, molecular compounds

when atoms share the outermost electrons

electric charged atom

formed when opposite charged atoms affect each other

2 or more substances mixed evenly
