Sickle-Cell Anemia is a genetic blood disorder caused by the presence of an abnormal form of hemoglobin. These hemoglobin molecules tend to aggregate after unloading oxygen forming long‚ rod-like structures that force the red cells to assume a sickle shape. Unlike normal red cells‚ which are usually smooth and malleable‚ the sickle red cells cannot squeeze through small blood vessels. When the sickle cells block small blood vessels‚ the organs are deprived of blood and oxygen. This leads to periodic

½Give an account of the structure and properties of Biological membranes. Include details of the modifications of membrane structure found in different specialised cells and organelles½ The Fluid Mosaic model was codified by Singer and Nicolson in 1972. It describes the structure and properties of the cell membrane very simply. Every membrane consists of a Phospholipid bilayer. This is simply two layers of phospholipid molecules that come together due to their unique properties. The heads of the

Damage of Beet Cell Membranes Caused by Different Temperatures Resulting in Betacyanin Leakage By: Trevor Sandum‚ Lab 2‚ March 9‚ 2013 Introduction: A red pigment called Betacyanin located in the vacuole of the beet cells is released when the membrane is damaged (Danyk‚ 2013). The membrane is necessary for sustainability of the cell’s life‚ it separates the cell from the outside environment‚ and is responsible for diffusion‚ exocytosis and endocytosis‚ and transport. It
