What causes these molecules in the plasma membrane of the cell lend stability to the membrane and prevent it from becoming less fluid at low tempatures?

Cholesterol molecules and protein molecules help stabilize the cell membranes. Cholesterol prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity. Cholesterol is only found in animal cells.

Stability of an animal cell plasma membrane is enhanced by?
cholesterol molecules because at warm temperatures, cholesterol reduces membrane fluidity by restraining the movement of phospholipids. At low temperatures, cholesterol hinders solidification of the membrane because it prevents the close packing of phospholipids.
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins

What is the membrane that surrounds the cells?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
How do small molecules get through the cell membrane against a concentration?
How do small molecules get through a cell membrane
What is most likely to occur if the sugar molecules cross the membrane?
Sugar molecules move outside of the membrane.

What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
Where are chlorophyll molecules located within plant cells?
chlorophyll molecules are located in the thylakoid membrane
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.
How do molecules jump?
they dont the molecules mov in and out of the cell membrane
