65.Myoglobin occurs in A. White muscle fibres B. Red muscle fibres C. Involuntary muscles D. All of the above
Option B Muscle is a bundle of fibrous tissue in a body that has the ability to contract, producing movement in or maintaining the position of parts of the body. The total number of muscles in the human body comes in the range of 640-850. Muscles appear in red color due to a pigment called myoglobin. It receives oxygen from the red blood cells and transports it to the mitochondria of muscle cells, where the oxygen is used in cellular respiration to produce energy. Hence myoglobin occurs in red muscle fibers. So, the correct answer is 'Red muscle fibers'.
