Science- Chapter 3 Vocab

Front 1

Active transport

Back 1

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

Front 2

diffusion

Back 2

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

Front 3

Endocytosis

Back 3

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

Front 4

enzyme

Back 4

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

Front 5

equilibrium

Back 5

occurs when moleciles of one substance are spread evenly thoughout another substance

Front 6

exocytosis

Back 6

process by which vesicles release their contents outside the cell

Front 7

fermentation

Back 7

process by which oxypgen lacking cells and some one celled organisms release small amounts of energy from glucose molecules and produce waste such as alcohal, carbon dioxide, and luctic acid

Front 8

inorganic compound

Back 8

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

Front 9

metabolism

Back 9

the total of all chemical reactions in an organism

Front 10

mixture

Back 10

a combination of substances in which the individual substances do no tchange or combine chemically but instead retain their own individual proprties; can be gases, soilds, liquids, or any combinations of them

Front 11

organic compound

Back 11

compounds that always contains hydrogen and carbon; carbohydrates, lipids, proteins, and necleic acids are organic compounds found in living things.

Front 12

osmosis

Back 12

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

Front 13

passive transport

Back 13

movement of substances through a cell membrane without the use of cellular energy; includes diffusion, osmosis, and fecilitated diffusion

Front 14

photosynthesis

Back 14

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

Front 15

respiration

Back 15

process by which producers and consumers release stored energy from food molecules; series of chemical reactions used to release energy stored in food molecules.
