At Room Temperature The Plasma Membrane Is Solid

Which of the following is a feature of lipids in plant membranes that best explains this difference.

At room temperature the plasma membrane is solid.

Think of a package of dry spaghetti noodles. A they are solid at room temperature b. In the golgi apparatus d. Think of a bag of dry macaroni noodles.

In the plasma membrane b. C before partial hydrogenation the shortening was vegetable fat and therefore solid at room temperature. Explain at least three functions that lipids serve in plants and or animals. All cells have mitochondria.

The reason that saturated fats are liquids at room temperature is that they can t fill nearly as much space with the same number of molecules. 1 t m melting temperature is a phase transition a change from a more rigid solid like state to a fluid like state measures of membrane fluidity. The plasma membrane of animal cells. In the mitochondria c.

Most animal fats form a solid at room temperature while plant fats remain liquid at room temperature. In the endoplasmic reticulum. B before partial hydrogenation the shortening was vegetable oil and therefore liquid at room temperature. Saturated phosphatidylcholine lipids with tails longer than 14 carbons are solid at room temperature while those with fewer than 14 are liquid.

All cells have a plasma membrane. They tend to dissolve in water easily. This phenomenon is analogous to the fact that paraffin wax which is composed of long alkanes is solid at room temperature while octane gasoline a short alkane is liquid. A before partial hydrogenation the shortening was animal fat and therefore solid at room temperature.

A membrane surrounds every living cell keeping the cell s interior separated and protected from the outside world. They have single bonds within the carbon chain c. Temperature helps determine what can enter or leave the cell and how well molecules found within the membrane can function. The reason that saturated fats are solid at room temperature is that the molecules are able to pack much closer together.

All cells have a cell wall. They are usually obtained from animal sources d. Melting temperature the fluidity ease with which lipids move in the plane of the bilayer of cell membranes has to. All cells have a flagellum.

Lard is a solid fat at room temperature. What does this tell you about the triglycerides in lard. Many factors affect how this membrane behaves and temperature is one of the most important. All cells have a nucleus.
