O.+Metabolism

METABOLISM: FUEL THE BODY! *Our body needs food to provide molecules used in cell respiration for energy *Our metabolic rate is influenced by physical activity, temperature, and eating *We use kilocalories as a measurement of units for the energy provided in foods and the energy consumed by our body *We gain stored fat by excess calories that we eat over out caloric consumption in comparison to the energy that we burn and use *Vitamins and elements help aid our body as cofactors and coenzymes *In cell respiration many water-soluable vitamins are key helpers *Fat soluble vitamins are A, D, E and K *We also classify vitamins as fat-soluble media type="youtube" key="QihqA8_MZpo" height="279" width="448" align="center"
 * I. "Feed Me!" **

*Our body tissues use circulating energy substrates that include fatty acids, lactic acid, glucose, ketone bodies, amino acids and others also for cell respiration *Different organs in our body have different preferred energy sources they use *Our hypothalamus regulates our eating behavior *Adipose cells (also called adipocytes) are targets of hormonal regulation *Adipocytes secrete leptin and leptin aids in regulation of our food intake and metabolism *The anabolic and catabolic effects of specific hormones in our body control the energy balance in our body  *Our bones contain calcium and phosphate known as a form of hydroxyapatite crystals *These crystals are a reserved supply for our blood in our body *Osteoblasts and osteoclasts produce the formation and reabsorption of bone in our body *The parathyroid hormone is responsible for stimulating bone reabsorption *It is secreted when there is a fall in our body from the blood calcium concentration *Calcitonin is also secreted by the parafollicular cells of the thyroid gland *It is secreted when there is a rise in blood calcium blood levels media type="youtube" key="jr05O7T3xT8" height="314" width="504" align="center"
 * II. Regulation of ENERGY Metabolism **
 * III. Regulation of Calcium and Phosphate Balance **

**APPLICATION:** The last area I covered was the regulation of calcium and phosphate balance. Something that we see a lot in the hospital pharmacy is supplements for calcium and phosphate. Calcitonin is a very common supplment that is used to actually lower blood calcium by inhibiting bone reabsoprtion. It also aids in stimulating the urinary excretion of phosphate and calcium. Overall there is so many hormones and vitamins that pharmacy aids in the treatment of patients by trying to conteract and respond to deficiencies in the body.
