The property of selective permeability exists only in living plasma membrane’’ . Design an experiment with a suitable illustration to verify the statement. *
Answers
Answer:
Transport across the Cell Membrane. ... The phospholipids are tightly packed together, and the membrane has a hydrophobic interior. This structure causes the membrane to be selectively permeable. A membrane that has selective permeability allows only substances meeting certain criteria to pass through it unaided...
Abstract
Biological membranes allow life as we know it to exist. They form cells and enable separation between the inside and outside of an organism, controlling by means of their selective permeability which substances enter and leave. By allowing gradients of ions to be created across them, membranes also enable living organisms to generate energy. In addition, they control the flow of messages between cells by sending, receiving , and processing information in the form of chemical and electrical signals. This essay summarizes the structure and function of membranes and the proteins within them and describes their role in trafficking and transport, and their involvement in health and disease. Techniques for studying membranes are also discussed.
