When phospholipids are added to an aqueous environment (consisting mostly of water) the phospholipid molecules will spontaneously assemble into a phospholipid bilayer where the layers are held together by weak attractive forces between molecules. These structures are often seen in nature as cell and organelle membranes. 12. Consider animal cells, which are only bound by a cell membrane and plant cells which are bound by both a cell membrane and a cell wall. Are cell membranes flexible (fluid)? Provide specific examples to support your answer. 13. Explain why a phospholipid bilayer is flexible. terms of the strength of the forces that hold it together. 14. Refer to Model 1. a. What happens to the shape of the hydrophobic tail in a phospholipid when a double bond is present in the carbon chain? b. Explain why the flexibility (fluidity) of a membrane increases when more of the phospholipids in the layers contain double bonds. 15.

Justify your label by features of the protein shown in the image. B) Describe the overall tertiary structure of each protein.

- - The classic demonstration that cell plasma membranes are com- posed of bilayers depends on the following kinds of data: • The membrane lipids from 4.74 x 10° erythrocytes will form a monolayer of area 0.89 m² when spread on a water surface. • The surface of one erythrocyte is approximately 100 µm? in area. Show that these data can be accounted for only if the erythrocyte membrane is a bilayer.arrow_forwardex51arrow_forward21.
