Back Pain

Low back pain can result in injury poor posture and being overweight or lack of fitness; it is the primary cause of missed work and the second most common neurological affliction in the United States. In addition to chronic pain, a low back injury is often accompanied by muscle spasms which are spontaneous painful, uncontrolled muscle contractions. A few changes may help prevent more spasms and reduce pain. Patients should sit and stand up straight: use a low back support when sitting; lose weight; exercise, especially the back and abdominal muscles; and try to sleep on their side on a firm mattress. If lifestyle changes are not sufficient, treatment with muscle relaxants. anti-inflammatory drugs. or pain medication may be necessary. I ow back pain can result from injury, poor posture, being over.

Chemical Reactions and Energy

Synthesis Reactions A chemical reaction occurs when atoms, ions, molecules, or compounds interact either to form or to break chemical bonds. Reactants are substances that enter into a chemical reaction, whereas the substances that result from the chemical reaction are called products. A synthesis reaction is when two or more reactants chemically combine to form a new and larger product. The synthesis reactions occurring in the body are collectively referred to as anabolism. These reactions produce the molecules characteristic of life, such as ATP, proteins, carbohydrates, lipids, and nucleic acids. Some conditions of the body such as growth, maintenance, and repair could not take place without anabolic reactions. Synthesis reactions in which water is a product are called dehydration (water out) reactions. Decomposition Reactions A decomposition reaction is the reverse of a synthesis reaction—a larger reactant is chemically broken down into two or more smaller products. T...

BIOLOGICAL MACROMOLECULES

Image
Bio-molecules are a subset of organic molecules. Organic molecules are defined as molecules or compounds that contain both carbon and hydrogen. Most organic molecules are a component of living organisms or have been produced from them. All other types of molecules are inorganic molecules including water, salts (e.g., sodium chloride), acids (e.g., carbonic acid), and bases (e.g., sodium hydroxide). The four major classes of organic biological macro-molecules (bio-molecules) are lipids, carbohydrates, nucleic acids, and proteins.
