Positive feedback mechanism is less common in nature T or F
the plasma membrane is __________ _________ which means is allows certain molecules to penetrate or permeate while excluding others
These type of molecules are non polar and readily diffuse across the lipid bilayer membrane without the aid of membrane proteins
Passive transport
Active transport
Passive transport if movement of molecules from high concentration to low concentration T or F
Simple diffusion
unassisted transport
Channel mediated facilitated diffusion
Channel proteins
hydrophilic proteins in lipid bilayer aid in the transport of small polar molecules and ions across the membrane T or F
Carrier Mediated Facilitated diffusion
What slows the transport of solute during carrier mediated facilitated diffusion?
Carrier mediated facilitated diffusion n transports molecules from _____ to ____ concentration
Primary Active Transport
Primary active transport involves the use of
In this form of transport, molecules are pumped against a concentration gradient at the expense of energy
Secondary active transport
In this form of transport the downhill movement of one molecule drives the uphill movement of another molecule
