Which structure is the statement below most likely referring to Small nonpolar molecules may pass through this structure but others require a protein channel.?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
What fuctions do cells carry out that require energy?
Metabolism motility protein pumps (sodium-potassium pump for example) creating gradients (chemical or electrical) Other protein pumps that shuttle anything against its gradient (from low to high concentration) Activation and/or deactivation of second messangers I am sure there are others...
What structure is small nonpolar molecules may pass through this structure but others require a protein channel?
A semipermeable membrane
Does pumps require energy?
Yes, they require a biofuel
What is this statement most likely referring to Small nonpolar molecules may pass through this structure but others require a protein channel?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
Do membrane pumps transport protein?
yes they can
What are the special structures in the cell membrane that allow materials such as water and sugar through made of?
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
The cell membrane contains channels and pumps that help move materials from one side to another What are these channels and pumps made of?
There are many different protein channels that only allow one substance to go in or out of the cell. For example, there is a specific channel for gluclose,and no other substane can go through that channel
Do sump pumps require a checkvalve?
Yes.
Did NaCl require a transport protein?
Did NaCl require a transport protein for diffusion?
What structure is this statement most likely referring to?

What channel can help move things across the membrane?
Protein channels help move particles across the cell membrane
