Do some membranes have proteins with chanels that allow for the passage of hydrophilic substances?
true
Is this true some membranes have proteins with channels or pores that allow for passage of hydrophilic substances?
yes it's true.
What type of membrane proteins allow cells to identify one another?
Receptor proteins.
Does chicken have a lot of proteins?
All organisms have a lot of proteins, as they allow us to function.
What type of molecules need more help to get through the membrane and What is help them?
Large or polar molecules typically need more help to get through the membrane. They rely on specialized transport proteins such as channels or carriers to facilitate their passage. These transport proteins create pores or binding sites that allow the molecules to cross the membrane.
Which organelle in a cell allows for the passage of proteins?
Nuclear Pores, Openings in the nuclear membrane allow the passing of proteins.
Do some membranes have proteins with chanels that allow for the passage of hydrophilic substances?
true
What are gap junctions?
are formed by a ringlike connexon which consist of six transmembrane proteins are arranged somewhat like the segment of an orange
Is this true some membranes have proteins with channels or pores that allow for passage of hydrophilic substances?
yes it's true.
What are the examples of types of channel protein?
Channel proteins are integral proteins (also transmembrane proteins) which has pores that allow passage of water and hydrophilic solutes through the cell membrane. some are open while others are gates that can be open or close in respond to different stimuli: 1. Ligand gate---> in respond to chemical 2. Voltage gate---> in respond ot electrical potential across the plasma membrane 3. Mechanical gate--> in respond to physical stress on a cell (strech,pressure)
What are the functions of a plasma membrane?
- Outer membrane of cell that controls cellular traffic- Contains proteins (left, gray) that span through the membrane and allow passage of materials- Proteins are surrounded by a phospholipid bi-layer
What the purpose of plasmodesmata?
Plasmodesmata are holes in the cell wall of plants and algae that allow the cellular transfer of of proteins and macromolecules in and out of the cell. The cell wall does not have gap junctions or intermembrane proteins like the cell membrane does, so the cell needed another way to allow passage into and out of the cell, which is where plasmodesmata developed.
What identifies proteins that allow muscles to shorten or lengthen?
Contractile proteins is the term that identifies the proteins that allow muscles to shorten or lengthen.

What type of membrane proteins allow cells to identify one another?
Receptor proteins.
What parts of a virus allow it to attach to a cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.

All organisms have a lot of proteins, as they allow us to function.
