Membrane proteins are key components of a typical cell membrane. Explain the importance of the proteins inside membranes to the cell membrane itself, and overall life. Include a diagram that illustrates . Your labelled diagram needs to show two different types of transport proteins embedded within a typical cell 1. membrane. 2. Serine is an uncharged, polar amino acid (below and left). Threonine (below and right) is another uncharged, polar amino acid. Illustrate the hydrolysis of a dipeptide that was made from these two amino acids. Be sure to write all involved reactants and products in the structural form like Serine, and as a proper chemical equation; e.g. reactant(s) - product(s). Your diagram of the dipeptide must show the N-terminal and C-terminal ends at opposite sides of the dimer molecule, and you need to indicate where the peptide bond is with an arrow/highlighter. „H C-N OH NH2 но CH — CH -с-соон он H
What Osmotic conditions would be favored by Plant and Animal cells? Why? Explain what is meant by the Fluid Mosaic Model of Membrane Structure. What are the various functions of membrane proteins? Explain the different forms of membrane transport: Passive, Facilitated, Active. Describe the bulk transport mechanisms of Endocytosis and Exocytosis.
The image below shows the movement of molecules across a plasma membrane. extracellular space lipid bilayer (cell membrane) TIMEI Source: LadyofHats small hydrophobic molecules intracellular space Using the image above, answer the following questions. (a) Identify the type of cell transport that is occurring in the image and justify your answer.

(c) Predict the difference you would expect to see in the movement of illustrated molecules if they were to represent hydrophilic molecules rather than hydrophobic molecules. Justify your
Being an integral membrane protein is critical to the function of which of the following protein complexes? Select all that apply. There is a minimum of one and a maximum of eight correct answers. Dynein Tubulin Integrin Complex III of the electron transport chain Collagen Aquaporin
of 15 > Biological membranes are selectively permeable, allowing certain molecules to cross the membrane, but not others. Classify the molecules or ions depending on how they cross a biological membrane. Note that some of these examples may also utilize active transport to traverse a membrane. However, this question is limited to passive transport processes only. lactose Simple Diffusion Mg²+ steroid hormones Answer Bank nucleosides Facilitated Diffusion
This graph represents two different modes of transport across a biological membrane. One shows a membrane protein and the other does not. Which line represents transport with a membrane protein? Label each line with the mode of transport. There are three key characteristics of transport across a biological membrane using a membrane protein. What are the three key features? List and describe each feature.
Membranes are effective barriers preventing the crossing of both polar and nonpolar molecules from one side to the other. Explain why it is difficult for any species to pass from one side of a membrane to the other, more specifically explain how membranes are able to keep polar molecules out of the cell, keep nonpolar molecules out of the cell and what region of the membrae the polar and nonpolar/ hydrophilic molecules will not like being assoicated with.
How is active transport different from simple diffusion? Both active transport and simple diffusion transport molecules against the concentration gradient. In active transport, molecules are moved down the concentration gradient; on the B contrary, molecules to be transported in simple diffusion are moved against the concentration gradient. In active transport, molecules are transported with the aid of transport proteins; on the © other hand, molecules to be transported in simple diffusion do not need transport proteins. In active transport, molecules that are transported does not need metabolic energy; in contrast, molecules transported in simple diffusion need metabolic energy.
The plasma membrane of E. coli is approximately 75% protein and 25% phospholipid by weight. It is known that the average membrane protein molecular weight is 50,000 Da and an average membrane phospholipid molecular weight is 750 Da. Calculate the number of membrane phospholipid molecules present per molecule of membrane protein. number of membrane phospholipid molecules: molecules Select the additional information that one would need to calculate the fraction of membrane surface covered by phospholipids. the average densities of a 50,000 Da protein and a 750 Da phospholipid the number of moles of protein and phospholipid in the membrane the surface area of the E. coli cell the average cross-sectional areas of a 50,000 Da protein and a 750 Da phospholipid in a bilayer
You will create a hand drawn, 2-dimensional, labelled diagram of the plasma membrane (not a 3D diagram). Label the following structures in your diagram: A phospholipid A peripheral protein An integral protein A cholesterol Intracellular and extracellular portion of the membrane Hydrophobic and hydrophilic areas Also include a detailed drawing of a single phospholipid labeling its component
In facilitated diffusion and active transport, how do transport proteins affect the rate of movement of molecules across the phospholipid selectively permeable membrane? A Transport proteins decrease the rate of movement of molecules. B Transport proteins stop the rate of movement of molecules. © Transport proteins increase the rate of movement of molecules. Transport proteins ensures all molecules may pass the membrane simultaneously.
Some nutrients and other types of particles can be taken into a cell when the cell's plasma membrane encloses the particles and pinches off, forming a free-floating vesicle inside the cell. A lysosome containing digestive enzymes then fuses with the vesicle. Which term best classifies the uptake of such particles by the cell? Simple diffusion OEndocytosis O Exocytosis Facilitated diffusion
