You are viewing two samples of mammalian red blood cells (erythrocytes) under a microscope. One first sample is made up of cells with a typical round shape. Most of the cells in the second sample had burst open. •Describe the properties of the solution that was used to prepare the second sample. • Identify one type of solute that can move through simple diffusion and does not affect osmotic pressure or require a membrane protein to cross a plasma membrane.
QUESTION 1 a) Figure 2 shows the fluid mosaic model of plasma membrane. Figure 2 i) Name the parts labelled A and B. A: .. ii) State the component and function of structure C. Component Function: b) Movement of solutes across a membrane occur with the help of transport protein. i) Name the disease due to defective carrier proteins that transport cystine. i) Name and describe one (1) type of gated ion channel. i) Explain how glucose molecules are transported across plasma membrane into a cell via passive transport.
Identify basic structure of the 8 types of membrane proteins shown below Understand how primary structure (e.g., regional hydrophobicity and hydrophilicity) allows proper membrane interaction/association. Compare/contrast the degree to which proteins are attached to membranes. Which have more lateral movement? Diversity of attachment and lateral movement allows efficient function. Understand where glycosylated lipids and proteins are found and what general functions they serve. Know the role/significance of cysteine disulfide bonds. On which side of the plasma membrane do they generally occur? Why? lipid bilayer A La s *****P & de www CYTOSOL COOH NH₂ cccccce 6
