Glencoe Science Cell Processes (Chapter 4)

Front 1

Element

Back 1

something made up of only 1 atom, cant be broken down by chemivcal means

Front 2

Compounds

Back 2

made up of 2 or more elements

Front 3

molecule

Back 3

a group of atoms held together by the energy of chemical bonds

Front 4

molecular compounds

Back 4

when diffrent atoms share their electrons

Front 5

ions

Back 5

positive or negitive electrically charged atoms

Front 6

ionic compound

Back 6

ions of oppisite charges attract one another to form eletracally muetral compounds

Front 7

Suspension

Back 7

formed when a liquid/gas has another substance mixed evenly throughout it.

Front 8

Organic

Back 8

must contain hydrogen and carbon, living

Front 9

carbohydrates

Back 9

organic, supplies enegry for cell process

Front 10

lipids

Back 10

release more energy than casrbs

Front 11

protiens

Back 11

made up of amino acids, building blocks of structures in organisms, scattered in membrane

Front 12

enzymes

Back 12

protiens, regulate all chemical reactions

Front 13

nucleic acids

Back 13

large organic molecules, stores important info in cells

Front 14

inorganic compounds

Back 14

no carbon, dead, fewer atoms than organic

Front 15

diffusion

Back 15

when atoms from a crowed area move to a less crowded place.
high to low

Front 16

facilitated diffusion

Back 16

the process when objects too big to fit into the membrane get helped by the transport protiens

Front 17

active transport

Back 17

when energy is used topass materials through the membrane

Front 18

vesicle

Back 18

transport/storage structures in the cytoplasm

Front 19

exotytosis

Back 19

when the vescils contents are released

Front 20

endocytosis

Back 20

when the vesicls take contents into the membrane

Front 21

enzymes

Back 21

work like can openers
reusable
can cause molecules to join

Front 22

photosynthesis

Back 22

when plants/producers use sunlight to make food

Front 23

resperation

Back 23

when food molecules are being broken down into simpliar substances

Front 24

fermentation

Back 24

when cells dont have engough oxygen for resperastion, they release some of the stored enegry
