Front 1

Fluid mosaic model

Back 1

model that describes the arrangement and movement of the molecules that make up a cell membrane.

Front 2

Selective Permeability

Back 2

condition or quality of allowing some, but not all, materials to cross a barrier or membrane.

Front 3

Receptor

Back 3

Protein that detects a signal molecule and performs an action in response.

Front 4

Diffusion

Back 4

Movement of dissolved molecules in a fluid or gas from a region of higher concentration to a region of lower concentraition.

Front 5

Concentration gradient

Back 5

Difference in the concetration of a from one to another location.

Front 6

Isotonic

Back 6

Solution that is equal concetration of a dissolved particle that is compared with another solution.

Front 7

Hypertonic

Back 7

Solution that has a higher concetration of dissolved particles compared with another solution.

Front 8

Hypotonic

Back 8

Solution that has a lower concetration of dissolved particles compared with another solution.

Front 9

Endocytosis

Back 9

uptake of liquids or large molecules into a cell by inward folding of the cell membrane.

Front 10

Exocytosis

Back 10

Release of substances out of the cell by fusion of a vesicle with the membrane.

Front 11

Phagocytosis

Back 11

Uptake a solid particle into a cell by engulfin the particle.

Front 12

Chemosynthesis

Back 12

Process by witch ATP is synthesized by using chemicals as an energy source.

Front 13

Chlorophyll

Back 13

light absorbing pigment molecule in photo synthetic organisms.

Front 14

Thylakoid

Back 14

membrane bound structure found within chloroplasts that contains chlorophyll and other light absorbing pigments used in the light- dependent reactions of photosynthesis.

Front 15

Photosystem

Back 15

Process that requires oxygen to occur

Front 16

Glycolysis

Back 16

Anaeorobic process in which glucose is broken down into two molecules of pyruvate and two net ATP are produced.

Front 17

Anaeorobic

Back 17

process that does not require oxygen to oocur.

Front 18

Fermentation

Back 18

Anaerobic process by which ATP is produced by glucolysis is produced.

Front 19

Lactic Acid

Back 19

product of fermentation in many types of cells, including han muscle cells.

Front 20

Front 26

Source

Back 26

anything or place from ehig somthing comes arisis or is obtained; origin

Front 27

Vary

Back 27

to changr or alter, as in form, appearence, character, or substance.
