Sodium: Sodium is essential to all living beings Basic functions: Sodium has 3 main functions: it helps in the absorption of glucose and some amino acids in the small intestine‚ it is required for normal muscle and nerve function‚ and it aids in water balance. Glucose generated by digestion of starch or lactose is absorbed in the small intestine only by cotransport with sodium‚ a fact that has exceptionally important implications in medicine. Glucose and galactose are taken into the enterocyte by

Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314

The Effects of Secondary Plant Compounds on Lumbriculus Variegatus Heart Rate Introduction Blackworms (Lumbriculus variegatus) were used in this experiment to study the effects of secondary plant compounds‚ chemical compounds produced by plants that are not part of the general metabolism‚ on pulse rate. Secondary plant compounds act as defense mechanisms which reduce or eliminate consumption of some plant species or even attract predators. These compounds are not essential to the plant but often

KNES 470 Dr Rubin 4-18-12 Sodium Bicarbonate and Boxing Performance Boxing is a sport which relies on anaerobic power since it contains short-duration and high intensity work. A typical boxing match today consists of 3 minute rounds with a 1 minute seated recovery rest. When an athlete performs exercise at maximal level for more than 30 seconds‚ most of the energy comes from anaerobic glycolysis. During this process‚ lactic acid is produced which causes a decrease in pH levels within the muscle

is among the top preventable risk factors of heart disease amongst many other health problems. Coronary heart disease and strokes are the primary types of cardiovascular disease caused by smoking. They rank as the first and third leading causes of death in the United States. More than 61 million Americans suffer from some form of cardiovascular disease. Smoking increases your risk for high blood pressure‚ coronary heart disease‚ stroke‚ congestive heart failure‚ and aneurysms to name a few. More

Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction.
