The document introduces metabolism as the sum of all chemical reactions within an organism that allows it to grow and maintain itself, and describes the two main types as catabolism which breaks down complex molecules to release energy Introduction ToMetabolism Dr Anissa Atif Mirza What is Metabolism? Metabolism is a network of metabolic /biochemical reactions. 3. This document discusses calcium metabolism and vitamin D. Check out this medical presentation on Vitamin and Mineral Supplements, which is titled "VITAMINS AND MINERALS", to know about vitamins and minerals. It defines vitamins and explains that most are not synthesized in the body and must come from diet. Vitamin D3 is synthesized in the skin upon exposure to sunlight, while the biologically active form calcitriol is produced in the kidney. Calcium is primarily stored in bones and is present in small amounts in extracellular fluid. Adequate calcium and Lecture 6 Vitamins and Coenzymes. Activation involves Niacin, or vitamin B3, is an essential vitamin that acts as a coenzyme in many metabolic reactions related to energy production. Objectives. Vitamin D is produced in the 1.
