Living things are highly organized

All living things have an ability to acquire materials and energy.

Archaea: very ancient prokaryotic microbes

Eubacteria: More advanced prokaryotic microbes.

Eukaryota: All life forms with eukaryotic cells including plants and animals

The first stage in clearing the blood is filtration

Tubular secretion is the passage of certain substances out of the capillaries directly into the renal tubules.

During reabsorption, needed substances in the filtrate travel back into the bloodstream. Reabsorption occurs in the renal tubules.

Cellular respiration

 Oxidoreductases: catalyze oxidation/reduction reactions

 Transferases: transfer a functional group (e.g. a methyl or phosphate group)

Hydrolases: catalyze the hydrolysis of various bonds

Lyases: cleave various bonds by means other than hydrolysis and oxidation
