Homeostasis enables the body’s system to function as expected because of proper temperature regulation. Dialysis is the process by which waste products are removed from the body by artificial ways by diffusion. The process of removal of waste products in a healthy person is facilitated by the kidneys. However‚ those individuals who suffer from kidney failure experience problems with waste removal thus dialysis has to be applied. While dialysis is in process‚ individuals with renal

Carbohydrate Absorption Sodium-glucose transport proteins (SGLT) in membrane help absorb glucose & galactose Fructose absorbed by facilitated diffusion then converted to glucose inside the cell Protein Digestion & Absorption Pepsin has optimal pH of 1.5 to 3.5 -- inactivated when passes into duodenum & mixes with alkaline pancreatic juice (pH 8) Pancreatic enzymes take over protein digestion

Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living

Overview: Life at the Edge The plasma membrane separates the living cell from its nonliving surroundings. This thin barrier‚ 8 nm thick‚ controls traffic into and out of the cell. Like all biological membranes‚ the plasma membrane is selectively permeable‚ allowing some substances to cross more easily than others. Concept 7.1 Cellular membranes are fluid mosaics of lipids and proteins The main macromolecules in membranes are lipids and proteins‚ but carbohydrates are also important. The
