Term used to describe a cell membrane means that the membrane contains different kind of molecules?
That kind of membrane in cells is called a mosaic membrane since the molecules are not all the same.
What else can I help you with?
Describe the water molecules move through the cell membrane during osmosis?
Describe how water molecules move through the cell membrane during osmosis?
The cell membrane contains lipid molecules that?
The cell membrane contains lipid molecules that provide a barrier to the free movement of ions into and out of the cell.
Which part of the cell surrounds the cell and allows molecules in and?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
What membrane bound sac in the cytoplasm contains digestive enzymes that can break down in large molecules?
lysosome
What is an antiporter?
An antiporter is a cell protein which acts within an antiport to transport different molecules or ions across the membrane in opposite directions.
Which part of the cell surrounds the cell and allows molecules in and out this cell part also has holes in it and is said to be semi-permeable?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
What is the model to describe the side to side movement of many different molecules in a cell membrane?
The model that describes the side-to-side movement of various molecules within a cell membrane is the Fluid Mosaic Model. This model depicts the cell membrane as a flexible, dynamic structure composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates. The lipid molecules can move laterally, allowing for the fluidity and diversity of interactions among membrane components, which facilitates various cellular functions.
What are some of the other molecules in the plasma membrane?
The cell membrane is mostly composed of phospholipids, but also contains proteins, cholesterol, glycolipids and carbohydrates (mostly glycoproteins).
Why are pores in the cell membrane different sizes?
They selectively allow certain size molecules to enter, or not to enter, the cell.
What controls what goes in and out of the nucleus?
The nuclear membrane, also known as the nuclear envelope, controls what goes in and out of the nucleus. It is a double membrane structure that surrounds the nucleus and contains pores that regulate the passage of molecules like proteins, RNA, and other molecules in and out of the nucleus.
What is the difference between symport and antiport?
Symport is a type of membrane transport where two different molecules are transported in the same direction across a membrane, while antiport is a type of membrane transport where two different molecules are transported in opposite directions across a membrane. In symport, the molecules move in the same direction to maintain equilibrium, whereas in antiport, the molecules move in opposite directions to create a gradient.
What is the functions to the cell membrane?
The Cell membrane contains the insides of the cell. The membrane is also selectively permeable, allowing nonpolar molecules to simply diffuse into the cells, such as lipids, steroid based hormones, CO2, etc. It also allows small polar molecules to diffuse through, such as H2O.
