Saturated three fatty acid one glycerol
Unsaturated attached to two
fatty acids and
one
phosphate
Proteins building blocks of proteins Essential amino acids Ammonia is
most important are amino acids cannot be synthesized by toxic to the
use of protein is the liver body
in the synthesis
of enzymes, liver
antibodies, converts the
structural ammonia to
protein, and urea
plasma proteins

Transcription Transcription occurs within
the nucleus as the code is
copied from DNA to mRNA
Translation Translation occurs along
the ribosomes (cytoplasm)
as the tRNA base­pairs with
the mRNA

REVIEW TISSUES AND MEMBRANES

TISSUES A tissue is a collection of cells HISTOLOGY
that are similar in structure and Study of tissues
function.
FOUR MAJOR TISSUES Epithelial
Connective
Muscular
Nervous

EPITHELIAL Continuous sheets, one surface Function: Protection,
unattached, avascular, ability to absorption, filtration and
regenerate secretion

Simple One layer Found in the lining of
