BAB 3 BIO T4 VIDEO PLASMA MEMBRANE + QUESTION

What does the "fluid" part of the Fluid Mosaic Model imply about the cell membrane?

• It is made entirely of water.

• Its components are constantly moving.

• It can change its shape to fit any molecule.

• It allows all fluids to pass through easily.

What unique property do phospholipids possess that allows them to form the cell membrane?

• They are entirely nonpolar.

• They are entirely polar.

• They have both a polar head and a nonpolar tail.

• They can dissolve in both oil and water completely.

What is a key difference between peripheral and integral proteins in the cell membrane?

• Peripheral proteins are involved in transport, while integral proteins are for cell recognition.

• Peripheral proteins are loosely attached to the surface, while integral proteins span the entire membrane.

• Integral proteins are only found in plant cells, while peripheral proteins are in animal cells.

• Peripheral proteins are always larger than integral proteins.

What is a primary function of glycoproteins and glycolipids on the cell surface?

• They provide structural support to the cell.

• They store energy for the cell.

• They are involved in cell identification and signaling.

• They regulate the cell's internal temperature.
