Basic components of all cells
plasma membrane
cytoplasm
nucleus
plasma membrane and functions
outer lining of the cell

selective barrier
communication
secretion
2 populations for proteins
integral and peripheral
Microvilli
fingerlike extensions of plasma membrane
tight junctions
proteins of plasma membranes fuse together to prevent leakage
gap junctions
hollow center allows molecules to pass thru
filtration
some molecules and water are pushed through membrane by hydrostatic pressure
simple diffusion/example
nonpolar (small and non-charged) molecules diffuse directly through the membrane.
Polar diffuse through protein channels.

ex: oxygen, carbon dioxide, vitamins, alcohol, anesthetics
facilitated diffusion/example
-When molecules too large move by protein carrier molecule.
-No energy is required.
-is at maximum when all carriers are occupied

ex: glucose
osmosis
When water molecules move and pass freely through a selectively permeable membrane.
vesicular transport
-requires enegery

-used for large particles and macromolecules
Exocytosis/examples
when substances inside the cell move outside of the cell.

ex- hormones(made and secreted)
-neurotransmitters
-mucous secretion
-cell waste
Phagocytosis
cell eating
Pinocytosis
cell drinking
Cytoplasm
-region between plasma membrane and nucleus

-composed of:
cytosol
organelles
molecules
pigments
90% of cell activity occurs here
cytoplasmic organelles
specialized cellular organs that each perform their own job.
what produces ATP?
mitochondria
Myoclonic Epilepsy
caused by the mutation of mitochondrial DNA (mtDNA)
where are ribosomes located and what do they do?
in the cytoplasm and they read the RNA code, help develop the protein and move it into the Endoplasmic Reticulum.
