Document Summary
Sum of all chemical reactions that occur in the body. Anabolic reactions: synthesis of molecules such as protein synthesis we are. Building up molecules, glucose to glycogen, fatty acids get built up into triglycerides (storage is associated with the glucose and fatty acid reactions) Bioenergetics: converting foodstuffs (fats, proteins, carbohydrates) into energy. Dna is kept in a closed and distinct compartment. Protein synthesis-cells constantly in a state where they are breaking down and being reformed, amino acids like bricks nucleus like blueprint reading dna. Need: materials (amino acids), a signal (muscle contraction-exercise or dietary amino acids- stimulate process to increase protein synthesis or hormones) Nps- net protein synthesis = protein synthesis- protein breakdown (exercise also increases this during exercise, right after exercise there is a window of opportunity to get protein synthesis) Milk is high quality protein and is easily digestible, lactose. Ingestion of a protein and a carbohydrate increases rate of protein absorption.
