What is the process in which molecules move in and out of cell?
The movement of things through the cell would be called diffusion. If it is water we are talking about then it is called osmosis. diffusion and osmosis are examples of inactive transport. Active transport involves specific proteins in the cell that pull material in the cell though the cell membrane.
What ways can cells move things by active transport?
. One method is that transport proteins in the cell membrane "pick up" molecules from outside the cell and carry them in, while using energy in the process. A second method is that the cell membrane surrounds a particle and takes it in.
Is protein synthesis a function of cell membrane?
Of course not,it is not a function of cell membrane.It is the function of ribosomes.
Water molecules diffuse through a selectively permeable membrane?
Water diffuses by facilitated diffusion, passing through water permeable protein channels embedded in the cell membrane. Water molecules can not pass through the lipid bilayer because water is polar. However, polar molecules pass though the cell membrane through the protein channels. The proteins that aid water in passing through the cell membrane are called aquaporins. "Aqua" for water, and "porin" for pore. A "water pore" in essence.
Make up the membrane of a cell?
A lot of different things... Mostly - a phospholipid bilayer, that's hydrophyllic on the outside and hydrophobic on the inside. It keeps liquid stuff contained within the membrane (inside the cell), as well outside, and doesn't let things normally pass though the membrane. Also - there are proteins embedded in the membrane that act as portals for specific chemicals to move in and/or out of the cell (usually requires energy to move things in or out - called active transport). Finally, there are a lot of other things embedded in the membrane - glycoproteins, cholesterol, etc. They give integrity to the membrane - keep it stable - when there are variations in temperature, pH, concentrations in salt, etc.
Which membrane activities require ATP?
Active transport... Not anything passive though.

Can proteins pass through transport proteins?
No the soluble proteins can not pass though the transporters on the membrane. Transport proteins are highly specific they only allow the transport of ions such as Na or K across the cell. But transport proteins such as Hemoglobin can carry oxygen or CO2 to all the tissues for respiration.
Does the phagocytosis process involves specific membrane receptors?
no that would be facilitated diffusion. nice try though.
How are oxygen and carbon dioxide exchanged in the Lings and though all cell membranes?
They enter/exit through a passive transport process called diffusion. It is caused by a concentration gradient within the two things being exchanged. The molecules diffuse across the membrane from the high concentration to the lower concentration side.

Which molecules are moved into a cell against their concentration gradient the process is?
Always active transport when something is moved against it's concentration gradient. Excepting, perhaps cotrasport, though many biologists see active transport here also.
Does diffusion always have to be though a membrane?
yes
Can a solution pass though a membrane?
yes
Explain how the transport layer correlates with process-to-process delivery?
The transport layer is in charge for process-to-process delivery of the intact message. An application program running on a host machine runs a process but the network layer run source-to-destination delivery of individual packets and it does not have any relationship between those packets. It's treated independently, as though each packet belonged to a separate message. The transport layer task is to ensure that the entire message arrives without error and in sequence and handles error control and flow control at the source-to-destination level.
