Bio Vocab 12-12

Front 1

diffusion

Back 1

net movement of particles from an area of higher concentration to an area of lower concentration.

Front 2

dynamics equilibrum

Back 2

conditions continuous , random movement of particles but no overall change in concentration of materials

Front 3

facilitated diffusion

Back 3

passive transport of ions and small molecules across the plasma membrane by transport proteins

Front 4

osmosis

Back 4

diffusion water across a selectively permeable membrane

Front 5

isotonic solution

Back 5

a solution with the same concentration of water and solutes as inside cell, resulting in the cell retaining its normal shape because there is no net movement of water

Front 6

hypotonic solution

Back 6

a solution that has lower concentration of solve outside than inside the cell ,causing water to flow into the cell by osmosis

Front 7

active transport

Back 7

energy- requiring process by which substance move across the plasma membrane aginst a concentration gradient

Front 8

endocytosis

Back 8

energy -requiring process by which large substance from the outside environment can enter a cell

Front 9

exocytosis

Back 9

energy - requiring process by which a cell expels was to and secrets subtances at the plasma membrane

Front 10

energy

Back 10

ability to do work and energy cannot be created or destroyed only transformed

Front 11

thermodynamics

Back 11

study of the flow and transformation of energy in the universe

Front 12

metabolism

Back 12

all of the chemical reactions that occur within an organism

Front 13

photosynthesis

Back 13

two phase anabolic pathway in which the suns light energy is converted to chemical energy for use by the cell

Front 14

cellular respiration

Back 14

catabolic pathway in which organic molecules are broken down to release energy for use by the cell

Front 15

ATP(adenonsinetriphosphate)

Back 15

energy carrying biological molecule which when broken down drives to release energy from use by the cell

Front 16

thylakoid

Back 16

in chyloroplasts one of the stacked flattened pigment-containing membranes in witch light dependent reactions occur

Front 17

granum

Back 17

one of the stacks of pigments containing thylakoids in a plants chloroplaste

Front 18

stroma

Back 18

fluid filled space outside the grams in which light dependent peat ions take place

Front 19

pigment

Back 19

light absorbing colored molecule such as chlorophy11 and carotenoid in the thylakoid membranes of choreplast

Front 20

NADP

Back 20

in photosynthesis the major electron carrier involved in electron transport

Front 21

calvin cycle

Back 21

light independent reactions during phase two of photosyntheisia which energy is stored in organic molecules as glucose
