Photosynthesis And Respiration Vocab

Front 1

Photosynthesis

Back 1

the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chorophyll

Front 2

cellular respiration

Back 2

the oxidation of organic compounds that occurs within cells, producing energy of cellular processes

Front 3

pigment

Back 3

any substance whose presence in the tissues or cells of animals or plants color them

Front 4

chlorophyll

Back 4

the green coloring matter of leaves and plants, essential to the production of carbohydrates by photosynthesis

Front 5

carotenoid

Back 5

any class of yellow to red pigments found especially plants, algae, and photosynthetic bacteria. the carotenoids absorb light energy of certain frequencies and transfer it to chlorophyll for use in photosynthesis

Front 6

carbon dioxide fixation

Back 6

the process by the which carbon from the atmosphere is converted into carbon compounds, such as casbohydrates, in plants and algae, usually by photosynthesis

Front 7

calvin cycle

Back 7

a series of chemical reactions that occur as a part of photosynthesis, in which carbon is broken away from gaseous carbon dioxide and fixed as organic carbon in compounds that are ultimately converted into sugars

Front 8

aerobic

Back 8

living or occuring only in the presence of free oxygen: aerobic bacteria

Front 9

anaerobic

Back 9

living or occurring in the absence of free oxygen: anaerobic bacteria

Front 10

glycolusis

Back 10

a metabolic process that occurs in nearly all living cells in which glucose is converted in a series of steps to pyruvic acid and during which energy is released in the from of atp

Front 11

fermentation

Back 11

any of a group of chemical reactions induced by microorganisms or enzymes that split complex organic compounds into relatively simple substances, especially the anaerobic conversion of sugar to carbon dioxide and alcohol by yeast

Front 12

stroma

Back 12

the colorless semlilquid material inside a chloroplast, in which the thylakiod membranes are embedded and where the dark reactions of photosynthesis occur

Front 13

ATP

Back 13

adenosine triphosphate; a nucleotide found in the mitochondria of all plant and animal cells. it is the major source of energy for cellular reactions, this energy being released duing its conversion toADP

Front 14

ADP

Back 14

adenosine diphosphate; a nucleotide derived from ATP with the liberation of energy that is then used in the performance of muscular work

Front 15

aero

Back 15

needing oxygen on air

Front 16

glyc

Back 16
