Photosynthesis

process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and glucose

Autotroph

an organism that makes its own food

Heterotroph

an organism that cannot make its own food

Cellular respiration

Process that uses glucose to make energy, ATP

Pigment

Light-absorbing molecule

Chlorophyll

Pigment

Carotenoids

Pigments

Thylakoids

A flattened membrane sac inside the chloroplast, used to convert light energy to chemical energy.

Electron transport chain

A series of molecules that excited electrons pass

NADPH

electron carrier that provides high-energy electrons to power the third stage of photosynthesis

Carbon dioxide fixation

The transfer of the carbon found in carbon dioxide into sugar (glucose)

Calvin cycle

reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugar

Aerobic

With oxygen

Anaerobic

Without oxygen

Glycolysis

1st step in cellular respiration producing pyruvate, ATP and NADH

NADH

Electron carrier

Kreb's Cycle

2nd step in cellular respiration producing Carbon dioxide, ATP, NADH and FADH2

FADH2

electron carrier

Fermentation

The 2nd step in cellular respiration when no oxygen is present, creates either lactate or ethanol & carbon dioxide
