Nhat type of system is this? O Steady State Diffusionn, no reaction Unsteady State Diffusion O Steady State Diffusion, with reaction O Pseudosteady State DA through stagnate B

Facilitated diffusion is a metabolically inexpensive process. O True O False

Name the membrane transport mechanism that Ca2* would most likely use to diffuse across the membrane. O simple diffusion O active transport O facilitated diffusion O vesicular transport O more than one of the above

Why is glucose being represented as line B? 

In diffusion, substances move from a _____ concentration to a _____ concentration. Select one: higher, lower lower, lower higher, higher lower, higher

What type of cellular transport do Epithelial sodium channels (ENaC)s perform? Group of answer choices Simple diffusion Secondary active transport Facilitated diffusion Primary active transport

What is the difference between passive diffusion and facilitated diffusion?

Discuss why the following affect the rate of diffusion:molecular size, temperature, solution density, and thedistance that must be traveled.

Facilitated diffusion is different from simple diffusion because O molecules are small. Owater is transported. energy is used. there is no concentration gradient. proteins act as helpers.

If a skeletal muscle has depleted its stores of ATP how will the altered transport properties of the following transporters affect cytosolic ion concentrations (increase, decrease, no change) relative to normal?   Skeletal Muscle Cell With Depleted ATP Stores Ion transporter Cytosolic K+ Cytosolic Na+ Cytosolic Ca2+ NKA         NCX         SERCA
