Glycogen is a homopolysaccharide formed by units of glucose and is sometimes referred to as animal starch. It can reach up to a molecular weight of 10 to the power 8 DA which corresponds to about 600,000 glucose molecules.
The function of glycogen is that it is the principal form in which glucose is stored in animals and is present in the liver, muscle (skeletal and heart muscle) and in lower amounts in nearly all the other tissues and organs.
Glycogen makes up about 10% of liver weight and 1% of muscle weight. Although it is present in higher a concentration in the liver, the total amount stored in muscles is much higher due the greater mass of the muscles as compared to the liver.
Answer: The correct option is D.
The concentration of calcium in the myofibril must decrease.
Explanation:
This is because calcium makes myosin, actin and ATP to interact which actually lead to the contraction of muscle fibre.
Relaxation of muscle fibres occurs when the nerves stop stimulating. The result in the pumping of Calcium into the sarcoplasmic reticulum which then cause a break in the link that connect actin and myosin. Actin and myosin return to their unbound state leading to the relaxation of the muscle .
The mass is made up of protons and neutrons, the valence electrons only determine stability, not mass

➷ It would be 'an increase in body temperature results from involuntary shivering.' As you may realize, when you stand in the cold, your body starts to shiver itself. This is from an effector producing a response to try increase your body temperature.
