What else can I help you with?
Does biological molecules proteins and lipids have cell membranes?
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
What 2 kinds of molecules are important in making cell membranes?
A phosphate group and a lipid (to form a phospholipid).
What two types of molecular movement across membranes require vesicles?
Endocytosis and exocytosis are the two types of molecular movement across membranes that require vesicles. Endocytosis involves the engulfment of molecules or particles into a cell by vesicles formed from the cell membrane, while exocytosis involves the release of molecules or particles out of a cell via vesicles fusing with the cell membrane.
What does osmosis have to do with cell membranes?
Osmosis is the water molecules diffusion across the cell membranes. More informations can be find at en.wikipedia.org/wiki/Diffusion
Does Cell Membrane have both animal and plant cells?
Yes. Both kinds of cells have nuclear membranes. They also have cell membranes, though plant cell membranes are also enclosed in the cell wall.
Which two kinds of molecules combine to form a cell membraine?
phospholipids and proteins
What cell part receives nerve impulses and hormones from other?
receptor molecules on cell membranes receptor molecules on cell membranes
Do hydrophobic molecules cross cell membranes?
Yes, hydrophobic molecules can cross cell membranes because cell membranes are made up of a phospholipid bilayer that is permeable to nonpolar molecules like hydrophobic ones.
Does biological molecules proteins and lipids have cell membranes?
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
Can large hydrophobic molecules cross cell membranes?
Yes, large hydrophobic molecules can cross cell membranes through passive diffusion.
What are proteins found in cell membranes that transport large molecules?
carrier molecules
What 2 kinds of molecules are important in making cell membranes?
A phosphate group and a lipid (to form a phospholipid).
What are the differences between hydrophilic and hydrophobic cell membranes and how do these differences impact the movement of molecules across the membrane?
Hydrophilic cell membranes are attracted to water, while hydrophobic cell membranes repel water. The differences impact the movement of molecules across the membrane because hydrophilic molecules can easily pass through hydrophilic membranes, while hydrophobic molecules can pass through hydrophobic membranes. This selective permeability allows the cell to control what substances enter and exit.
What two types of molecular movement across membranes require vesicles?
Endocytosis and exocytosis are the two types of molecular movement across membranes that require vesicles. Endocytosis involves the engulfment of molecules or particles into a cell by vesicles formed from the cell membrane, while exocytosis involves the release of molecules or particles out of a cell via vesicles fusing with the cell membrane.

What do cell membranes look like and how do they function within a cell?
Cell membranes are composed of a double layer of phospholipid molecules with proteins embedded within them. These membranes have a fluid structure that allows them to regulate the passage of substances in and out of the cell. They function as a barrier to protect the cell and also play a role in cell communication and signaling. Additionally, cell membranes contain specialized proteins and channels that facilitate the transport of molecules across the membrane.
Does Cell Membrane have both animal and plant cells?
Yes. Both kinds of cells have nuclear membranes. They also have cell membranes, though plant cell membranes are also enclosed in the cell wall.
