Weba. the membrane is a phospholipid bilayer. b. some proteins span the membrane. c. protein is found only on the surfaces of the membrane. d. glycolipids and glycoproteins are antigenic. e. there are receptors in the membrane. Verified answer physics Weba) The graph shows that, as temperature increases, the phospholipid bilayer becomes more fluid. Tm is the tempera- ture of the transition from the predominantly less fluid state to the predominantly more fluid state. Cholesterol broadens the transition from the less-fluid to the more-fluid state.

WebAug 31, 2024 · Phospholipids take an active role aside from forming bilayers. Phospholipids maintain a gradient of chemical and electrical processes to ensure cell survival. They are also essential to regulate exocytosis, chemotaxis and cytokinesis. Some phospholipids play a role in phagocytosis, working to surround particles to form phagosomes. WebA) Cholesterol binds to the outside surface of a membrane, thus blocking the movement of solutes. B) Because cholesterol is amphipathic, it forms tiny vesicles that trap solutes. C) Because cholesterol is amphipathic, it fits in between the phospholipids and blocks diffusion through the membrane.
