The fluid mosaic model describes the structure of the plasma membrane. Embedded within the plasma membrane are proteins and carbohydrates that contribute to the term mosaic. Carbohydrates on the surface of red blood cells are what determines ABO blood type. These carbohydrates are important for O Cell identification Active transport Diffusion Stability

When a human white blood cell “consumes” a red blood cell (erythrocyte), this process is called: phagocytosis receptor-mediated endocytosis pinocytosis “cell-drinking” exocytosis

Describe the specific situations where the plasma membrane of cells will not spontaneously re-seal. Give examples when necessary.

There are 4 basic tissues in the human body. For each of the following organs/structures describe the location and function of at least three basic tissues found in them. Heart and stomach You have received GHS 1 million as a scientist to develop a vaccine for corona virus. You have been able to develop the vaccine but now the challenge is how the vaccine will enter the cells of the body when you inject it. From your knowledge of the structure of the cell membrane give and explain 2 features you can exploit in order for the vaccine to go across the cell membrane into the cell.

Item17       Item 17 Which is a passive transport process? Multiple Choice   Phagocytosis   Pinocytosis   Receptor-mediated endocytosis   Osmosis   Ion pump Item18       Item 18 The type of vesicular transport by which large molecules or large amounts of substances are secreted from a cell is _________. Fill in the blank Fill in the blank   Item19       Item 19 Materials tend to move less rapidly when their concentrations are significantly different between two compartments. Group startsTrue or False   Item19       Item20       Item 20   As potassium diffuses down its concentration gradient, it moves out of the cell. However, this movement is resisted by the accumulating negative charge outside the cell.   Group startsTrue or False

You design a new matrix to regenerate skin during skin graft. The matrix have cells that need nutrients, such as glucose. You need to figure out the diffusion profile of glucose into the matrix. Assuming glucose has a radius of 1.0nm, you are interested in diffusion from the blood vessels into the matrix, which are 1cm away. The blood viscosity is 3cP, and the glucose concentration in the blood is 4mM. What is the initial flux of glucose? (use 1.38 * 10^-23 J/K for Boltzmann's constant).

Label the nucleus, cytoplasm, and cell membrane of the following pictures. The red one is the human red blood cell under HPO, while the orange one is the toad red blood cell. Describe each cell and compare the two.

A, B & C

What is the cause of the impermeability of plasma membranes to water-soluble molecules?  Group of answer choices   the nonpolar nature of water presence of phospholipid bilayer with a nonpolar/hydrophobic interior region presence of transmembrane proteins the presence of cellulose

Describe the chemical composition of membranes. What are the two most critical functions of membranes? What contributes to membrane fluidity and rigidity? Explain Diffusion.  What are the differences between Osmosis and Dialysis? Explain the differences between Iso, Hypo, and Hypertonic conditions.  If the solutions is Hypertonic then the cell would be?
