Summary Introduction
Introduction: Skeletal muscles are usually attached to bone by tendons and composed of numerous muscle fibers. Each muscle fiber contains hundreds to thousands of myofibrils which are small thread- like structure of the sarcoplasm. In myofibril, actin thin filaments and myosin thick filaments are organized into a linear chain of highly ordered structure, called sarcomeres. The actin filaments are attached to a so-called Z disc, from which the actin filaments interlink with the myosin filaments.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place.
