High myoglobin content and intermediate glycolytic enzyme activity are

1.	High myoglobin content and intermediate glycolytic enzyme activity are the characteristics of which of the following?(a) White fibres type of muscles(b) Fast oxidative or aerobic muscles(c) Cross-bridge structure(d) None of the above
Answer» Answer is : (b) Fast oxidative or aerobic muscles Myoglobin content and number of mitochondria are high in some muscles. They are called red muscle fibres. The high myoglobin content in them facilitates production of ATP by oxidative phosphorylation. They also have a moderate ability to generate ATP through glycolytic pathway. In white muscle fibres, there is accumulation of low or no myoglobin.

Answer is : (b) Fast oxidative or aerobic muscles

Myoglobin content and number of mitochondria are high in some muscles. They are called red muscle fibres. The high myoglobin content in them facilitates production of ATP by oxidative phosphorylation. They also have a moderate ability to generate ATP through glycolytic pathway. In white muscle fibres, there is accumulation of low or no myoglobin.
