NEET BIOLOGY

Detailed explanation-1: -Myofibrillar Proteins: Muscle fibers are composed of myofibrils. The proteins that comprise the myofibril, including actin and myosin and several more. The myofibrillar protein components most important for muscle fiber structure are actin and myosin.

Detailed explanation-2: -Proteins. Proteins are the primary building materials of the body. Your hair, skin, muscles, and organs are composed mostly of proteins.

Detailed explanation-3: -Proteins such as myoglobin, myogen, myoalbumin and x-globulin are found in the sarcoplasm and proteins such as elastin, collagen and reticulin are also found in the muscle. The remaining of proteins includes myofibrillar proteins of the Z-disc as well as small quantities of other proteins.

Detailed explanation-4: -Proteins, lipids, and sugars are the major building blocks of animal tissues. These structural biomolecules store a wealth of biological information at different levels of hierarchical organization (1).

Detailed explanation-5: -Carbohydrates are energy-rich biomolecules. They are one of the major nutrients required by many living organisms because they provide the body with a source of chemical energy.
