Science Flash Cards

Front 1

Photosynthesis

Back 1

the synthesis of complex organic materials, esp. carbohydrates, from carbon dioxide, water, and inorganic salts, using sunlight as the source of energy and with the aid of chlorophyll and associated pigments.
Use photosynthesis in a Sentence

Front 2

Autotroph

Back 2

any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists

Front 3

Heterotroph

Back 3

an organism requiring organic compounds for its principal source of food.

Front 4

Cellular Respiration

Back 4

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

Front 5

Pigment

Back 5

a dry insoluble substance, usually pulverized, which when suspended in a liquid vehicle becomes a paint, ink, etc.

Front 6

Cholorophyll

Back 6

the green coloring matter of leaves and plants, essential to the production of carbohydrates by photosynthesis, and occurring in a bluish-black form

Front 7

Carotenoid

Back 7

any of a group of red and yellow pigments, chemically similar to carotene, contained in animal fat and some plants.

Front 8

Thylakoid

Back 8

a flattened sac or vesicle lined with a pigmented membrane that is the site of photosynthesis, in plants and algae occurring in interconnected stacks constituting a granum of the chloroplast, and in other photosynthesizing organisms occurring either singly or as part of the cell membrane or other structure.

Front 9

Electron Transport Chain

Back 9

series of molecules th5ough passing along a thylakid membrane

Front 10

NADPH

Back 10

biochem the chemically reduced form of NADP

Front 11

Carbon Dioxide Fixation

Back 11

transformation from Carbon Dioxide to organic compunds

Front 12

Calvin Cycle

Back 12

botany a series of reactions, occurring during photosynthesis, in which glucose is synthesized from carbon dioxide

Front 13

Aerobic

Back 13

requiring the presence of air or free oxygen for life.

Front 14

Anaerobic

Back 14

living in the absence of air or free oxygen.

Front 15

Glycolysis

Back 15

the catabolism of carbohydrates, as glucose and glycogen, by enzymes, with the release of energy and the production of lactic or pyruvic acid.

Front 16

NADH

Back 16

an abbreviation for the reduced form of NAD in electron transport reactions

Front 17

Krebs Cycle

Back 17

a cycle of enzyme-catalyzed reactions in living cells that is the final series of reactions of aerobic metabolism of carbohydrates, proteins, and fatty acids, and by which carbon dioxide is produced, oxygen is reduced, and ATP is formed.

Front 18

Fermentation

Back 18

the act or process of fermenting.
