Q. A student was given sample of two muscles marked as 1 and 2. When he compared the muscles he found that muscle 1 contains large amount of myoglobin and utilize large amount of stored oxygen for ATP production whereas muscle 2 contains few myoglobin, mitochondria and high sarcoplasmic reticulum. Identify the correct conclusion regarding the muscle 1 and 2 from the option given below.
