Bio Stuff 3 Flashcards
Membrane technologies
The industrial use of synthetics to mimic natural functions
Recognition proteins
- embedded in the cell membrane, stick out into the cell’s surroundings, allow cells to recognize one another(I.e. pain)
How do receptor proteins bring molecules into the cell?
Bind to the molecules and bring into the cell via endocytosis
If the molecules are not brought into the cell, how do the receptor proteins work?
Communicate through the cell membrane. Pharmaceutical research targets certain receptors.
What vaccine uses receptor proteins to enter the cell?
HIV
What is the lock and key process?
Like covering the keyhole of padlock with cement; could be used to block viruses from binding to the receptor proteins
What is the difference between integral and peripheral receptors?
Integral goes through the entire cell, peripheral doesn’t
What are liposomes
Fluid filled sacks surrounded by the phospholipid bilayer, used to deliver drugs
What are liposomes usually used for
To deliver drugs
What’s a hormone
A chemical compound that travels from where it is produced in the organism to other places where it produces and effect; binds with membrane receptors
What is insulin
Small protein produced in the pancreas; helps your body turn food into energy and controls your blood sugar levels.
What is dialysis and how does it work
Uses diffusion/osmosis to keep kidneys in better condition; gets rude if the blood of toxins, wastes, be excess fluid produced by cells of the body
What is pertioneal dialysis?
Less severe kidney malfunction; collects waste from washing the empty space in your abdomen, the peritoneal cavity
What is hemodialysis?
More severe; cleans your blood through your arm, cleansed with the dialysate fluid and then returned to the body.
Reverse osmosis
E.g. desalination; requires pressure, going from low concentration of water to high, filters.
