7Th Grade Science

Front 1

combination of substance in which individual substances retain their own properties

Back 1

mixture

Front 2

compounds that always contain hydrogen and carbon,
carbohydrates, lipids, proteins and nucleic acids found in living things

Back 2

organic compounds

Front 3

type of protein that regulates nearly all chemical reactions in cells. type of protein that speeds up chemical reactions in the body without being changed or used up itself

Back 3

enzyme

Front 4

compound, such as H2O that is made from elements other than carbon & shose atoms usually can be arranged in only one structure

Back 4

inorganic compound

Front 5

movement of substances through a cell membrane without the use of cellular energy including diffusion osmosis and facilitated diffusion

Back 5

passive transport

Front 6

a type of passive transport in cells in which molecules move from areas where there are more of them to areas where there are fewer of them

Back 6

diffusion

Front 7

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

Back 7

equilibrium

Front 8

type of passive transport that occurs when water diffuses through a cell membrane

Back 8

osmosis

Front 9

energy-requiring process in which transport proteins bind with particles and move them through a cell membrane

Back 9

active transport

Front 10

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

Back 10

endocytosis

Front 11

process by which vesicles release their contents outside the cell

Back 11

exocytosis

Front 12

the total of all chemical reaction in an organism

Back 12

metabolism

Front 13

process by which plants and many other producers use light energy to produce imple sugar from carbon dioxide and water and give off oxygen

Back 13

photosynthesis

Front 14

chemical reactions occur that break down food molecules into simpler substances and release their stored energy

Back 14

cellular respiration

Front 15

process by which oxygen lacking cells and some one-celled organisms release small amounts of energy from glucose molecules and produces wastes such as alcohol carbon dioxide & lactic acid

Back 15

fermentation
