Energy In Living Things

Front 1

photosynthesis

Back 1

process in which light energy is converted into chemical energy

Front 2

autotrophs

Back 2

organisms that use energy from sunlight or from chemical bonds in inorgonic compounds to make organic compounds

Front 3

Heterotrophs

Back 3

Organisms that must get energy form food instead of directly from the sunlight or inorganic substances

Front 4

Cellular respiration

Back 4

A metabolic process similar to burning fuel. While burning converts almost all of the energy in a fuel to heat, cellular respiration releases much of the energy in food to make ATP. This ATP provides cells with the energy they need to carry out the activity of the cell.

Front 5

Electron transport chain

Back 5

The series of molecules through which excited electrons are passed along thylakoid membranes.

Front 6

NADPH

Back 6

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

Front 7

Carbon dioxide fixation

Back 7

The transfer of carbon dioxide to organic copounds

Front 8

Calvin cycle

Back 8

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

Front 9

Aerobic

Back 9

Metabolic process that requires oxygen

Front 10

Anaerobic

Back 10

Metabolic process that does not require oxygen

Front 11

Glycolysis

Back 11

an enzyme-assisted anaerobic process that breaks down one six-carbon molecule of glucose to two three- carbon pyruvate ions.
