Flashcards in Cell Physiology Deck (36):
Contains DNA, Histones & Chromosomes, has nucleolus
Powerhouse of the cell
Involve in detoxification, lipid synthesis, lipid soluble substances to water soluble substances
Agranular endoplasmic reticulum (SER)
For synthesis of proteins bound for
the cell membrane, lysosomes, outside of the cell
For synthesis of proteins bound for the cytoplasm & mitochondria
Free floating ribosomes
For packaging, molecular tagging & synthesis of hyaluronic acid & chondroitin sulfate
Contains proenzymes, neurotransmitters & replenishes cell membrane components
For regression of tissues & autolysis; suicide bags of cells; destroys FB
Degrades membrane-associated proteins; not membrane bound
Contains oxidases, catalases, for detoxification

What do you call the specialized RER in the neuron?
The only substance modified in the RET & not the Golgi apparatus
What is added ti lysosome-bound proteins by the Golgi apparatus?
Lysosomes come from which organelle?
Perixisomes come from which organelle?
Wear & tear pigmenta that accumulates in lysosomes
Disease with dynein missing in cilia & flagella
What is the explanation for the situs inversus in Kartagener's syndrome
Defective primary cilia
What is the functional unit of the gap junction?
What do you call the movement of substance through the apical & basolateral side?

Example of impermeant solute
Glucose (effective osmole)
Example of Permeant solute
Urea (ineffective osmole)
Effective osmole used in the treatment of brain edema
Osmotic pressure from large molecules (proteins)
Weight of the volume of a solution divided by weight of equal volume of distilled (pure) water
Ca-ATPase pump in the cell membrane
Ca-ATPase pump in the sarcoplasmuc reticulum & endoplasmic reticulum
Functions of the Na-K-ATPase pump
Contributes to RMP; prevents cellular swelling
Functional subunit by Na-K-ATPase pump inhibited by cardiac glycosides
In all epithelial cells, Na-K- TPase pump is found in the basolateral side EXCEPT:
