Front 1

Photosynthesis

Back 1

Light energy is converted to chemical energy

Front 2

Autotrophs

Back 2

Organisms that use energy from sunlight to make organic compounds

Front 3

Heterotrophs

Back 3

Organisms that must get energy from food.

Front 4

Cellular Respiration

Back 4

Metabolic process that releases much of energy in food to make ATP.

Front 5

Pigments

Back 5

Structures containing light-absorbing substances

Front 6

Chlorophyll

Back 6

Primary pigment involved in photosynthesis. Absorbs blue and red light and reflects green and yellow light.

Front 7

Carotenoids

Back 7

Pigments that produce yellow and orange fall leaf colors

Front 8

Thylakoids

Back 8

Clusters of pigments are embedded in the membranes of disk-shaped structures

Front 9

Electron transport chains

Back 9

The series of molecules through which excited electrons are passed along a thylakoid membrane

Front 10

NADPH

Back 10

Electron carrier that provides the high energy electrons needed to make carbon-hydrogen bonds in the third stage of photosynthesis

Front 11

Carbon dioxide fixation

Back 11

The transfer of carbon dioxide to organic compounds

Front 12

Calvin cycle

Back 12

A series of enzyme-assisted chemical reactions that produces a three-carbon sugar.

Front 13

Aerobic

Back 13

Metabolic processes that do require oxygen

Front 14

Anaerobic

Back 14

Metabolic processes that do not require oxygen

Front 15

Glycoysis

Back 15

is an enzyme-assisted anaerobic process that breaks down 1/6 carbon molecule of glucose

Front 16

NADH

Back 16

An electron carrier

Front 17

Krebs Cycle

Back 17

Acetyl-CoA enters a series of enzyme-assisted reactions

Front 18

FADH2

Back 18

Step 4 in Krebs cycle which is another type of electron carrier

Front 19

Fermentation

Back 19

The recycling of NAD+ using an organic hydrogen acceptor
