Source of energy for muscle contraction

Image
 Chemical composition of muscle • Skeletal Muscle 1. Water : ≈75% the muscle weight 2. Muscle proteins : ≈20% of the muscle mass • contractile proteins (actin, myosin, troponin and tropomyosin) • Myogen, myoglobin. 3 . Organic substances : • Carbohydrates : glycogen and hexaphosphate • Lipids : neutral fat, cholesterol, lecithin and steroids • Nitrogenous substance s : ATP, adenylic acid, creatine, phosphocreatine, urea, uric acid, xanthine and hypoxanthine. 4. Inorganic substances: • Cation s : potassium, sodium, calcium, magnesium and • Anions : chloride, phosphate and sulphate. Energy source for muscle contraction • Muscle contraction requires lot of energy • “a machine for converting chemical energy into mechanical work” • Immediate source of energy: ATP • Ultimate source: intermediary metabolism of carbohydrate and lipids. Adenosine Triphosphate • Adenosine-PO3 ~ PO3 ~ PO3 ( HIGH  ENERGY COME DUE TO PHSPHATE BOND BREAK DOWN) • 7300 calories of energy per mole of A...

 Unraveling the complexities of Alzheimer's disease, a relentless foe, has long been a subject of fascination and concern within the healthcare arena. In this blog, we embark on a journey to unravel the mysteries of Alzheimer's—exploring its causes, understanding its symptoms, and finding the glimmers of hope that light the way to a better future. 1. Alzheimer's Enigma: Causes Unveiled Understanding the roots of Alzheimer's is critical to developing effective treatments. We focus on the genetic, environmental, and lifestyle factors that contribute to the onset of this challenging disease. From family links to the role of certain proteins, we piece together the complex puzzle of what causes Alzheimer's. 2. Navigating the Maze : Recognizing Alzheimer's Symptoms Alzheimer's manifests itself through a series of cognitive and behavioral changes. We guide you through the early signs, from memory loss to mood swings, helping you spot the subtle signs that often ...
