Is active transport the only way substances can cross the intestinal membranes?
Diffusion too.
The transport mechanism for a neurotransmitter across the synaptic cleft is called?
simple diffusion
What transport process does oxygen move across the cell membranes and into your red blood cells?
diffusion
What is facilitated transport?
Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane transport proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.
Three types of passive transport?
There are three forms of passive transport, or the movement of biochemical and other atomic or molecular substances across the cell membranes. They are: osmosis, simple diffusion or facilitated diffusion, and filtration.
What are capillary transport mechanism?
diffusion through the membranes bulk flow transport via vesicles or caveolae
Which transport mechanism causes the respiratory gases to move across the alveolar pulmonary capillary membranes?
Diffusion
Absorption mechanism that requires energy?
Active transport
Is active transport the only way substances can cross the intestinal membranes?
Diffusion too.
The transport mechanism for a neurotransmitter across the synaptic cleft is called?
simple diffusion
Which transport mechanism is most probably functioning in the intestinal cells?
facilitated diffusion
What transport process does oxygen move across the cell membranes and into your red blood cells?
diffusion
What are 5 Mechanism of cellular exchange?
active transport, osmosis, exocytosis, endocytosis, and diffusion.

Ions diffuse across membranes down their what?
Its an active transport and use sodium channel generally _____ Diffusion is itself a pathway of travel across a cell membrane. Diffusion can be "simple diffusion" which is simply an ion moving across the membrane anywhere, or "fascilitated diffusion", where an ion moves across the membrane in a specific channel. Either way, diffusion involves the movement of that ion along its concentration gradient and requires no energy. Active transport is not the same as diffusion. Active transport requires energy.
How do transport proteins move substances across membranes?
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport, facilitated by integral proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.*This is from Wikipedia.....
