- "Although lipid molecules are free to diffuse in the plane of the bilayer, they cannot flip-flop across the bilayer unless enzyme catalysts called phospholipid translocators are present in the membrane", is true or false.arrow_forwardWhat materials can easily diffuse through the lipid bilayer, and why? What is receptor-mediated endocytosis said to be more selective than phagocytosis or pinocytosis? What do osmosis, diffusion, filtration, and the movement of ions away from like charges all have in common? In what do they differ?arrow_forward(a) Describe permeability of a phospholipid bilayer for the following molecules. Use terms: non-permeable, high permeability, medium permeability. N2, O2, Na+, glucose, sucrose (disaccharide), glycogen, H2O, KCl, K+, Mg2+, glycine and protein (b) Discuss the role of carbonic anhydrase in CO2 transport.

- Why are newly synthesized lipids added to the cytosolic side of the bilayer and not the lumen side and how is this problem addressed?arrow_forwardIn general terms, what would you expect to be different about the permeability of a lipid bilayer made of phospholipids (modern cells) and a bilayer made of fatty acids (protocell)?arrow_forwardDescribe the lipid bilayer structure of a cell membrane. What are the roles of proteins in membrane structure?arrow_forward
- Phospholipids form the main fabric of the plasma membrane. One feature of phospholipids is that when they are placed in an aqueous solution, they will self-assemble into a double layer (bilayer) that resembles the bilayer of the plasma membrane. This self-assembly occurs because phospholipids are hydrophilic at one end (the phospholipid head) and hydrophobic at the other end (the phospholipid tails). Drag the labels to their appropriate locations in the figure. 1. First, drag labels of Group 1 to targets (a) and (b) to indicate whether these environments are hydrophilic or hydrophobic. 2. Next, drag the phospholipid layers (Group 2) to targets (c) and (d) to indicate how they are oriented in the plasma membrane. 3. Finally, drag labels of Group 1 to targets (e), (f), and (g) to indicate which portions of the membrane protein are hydrophilic and which are hydrophobic. Group 1 extracellular hydrophobic fluid © hydrophilic plasma membrane Group 1 Group 2 (f membrane protein Group 1 Group…arrow_forwardName: b) Cellular membranes are generally found in environments that contain lots of water. Draw a diagram of what the phospholipid bilayer of a plasma membrane would look like if it were placed in a hydrophobic environment. (**Note that you only have to draw the phospholipid bilayer, you don't have to draw the other major components again as you did in part a) c) What part or parts of a cellular membrane play(s) a role in determining the fluidity of the membrane? 8) Indicate which of the five major types of membrane protein (adhesion, enzymatic, recogniti receptor, and transport) is most likely to be involved in each of the situations described below: a) An oncologist wants to study the cells from a certain tumour that has been surgically remov from a patient. However, she must first treat the tumour with a solution affects a membrane protein on the tumour cells. Because of the effect of the solution on the membrane protein, the tumour tissue falls apart into individual cells. Type of…arrow_forwardAmmonia (NH3) is a weak base that under acidic conditions becomes protonated to the ammonium ion in the following reaction: NH3 + H+ → NH+4 NH3 freely permeates biological membranes, including those of lysosomes. The lysosome is a subcellular organelle with a pH of about 4.5–5.0; the pH of cytoplasm is about 7.0. What is the effect on the pH of the fluid content of lyso- somes when cells are exposed to ammonia? Note: Ammo- nium (NH4+) does not diffuse freely across membranes.arrow_forward
