Active transport: requires that a cell expend energy to move molecules across a membrane against the solute’s concentration gradient (the side where it is more concentrated) Feedback inhibition: Metabolic reaction is blocked by its products. A product acts as an inhibitor of one of the enzymes in the pathway to regulate metabolism. Centriole: a structure in an animal cell composed of microtubule triplets arranged in a 9+0 pattern. An animal usually has a pair of centrioles within each of its centrosomes

The plasma membrane is a fluid phospholipid bilayer. The outside of the bilayer is hydrophilic portions of porteins and phospholipids because they are exposed to water. This results in a stable membrane structure. Inside the bilayer hydrophobic portions of proteins and phospholipids because the inside of the bilayer is nonaqueous. the proteins bob in the fluid bilayer of phospholipids. The proteins also vary in structure and function. There are teh integral proteins; transmembrane

Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

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

Transport; Containerization Transport or transportation is the movement of people‚ animals and goods from one location to another. Modes of transport include air‚ rail‚ road‚ water‚ cable‚ pipeline‚ and space. The field can be divided into infrastructure‚ vehicles‚ and operations. Transport is important since it enables trade between people‚ which in turn establishes civilizations. The transport systems
