Answer:
The correct answer will be option-They have about the same endurance as skeletal muscle fibers.
Explanation:
Cardiac muscle is one of the three types of muscle which is present in the Heart of the organism.
The muscle fibres of the cardiac muscle possess a high amount of myoglobin- an Oxygen carrying molecule which can store the oxygen for some time.
The cardiac muscles have to pump blood in the body, for which they require a high amount of ATP, so they possess larger mitochondria.
The studies have shown that the cardiac muscles store glycogen carbohydrate which is used during the relaxation phase in stress conditions.
Since the cardiac muscles do not have the same endurance as the skeletal muscles which with physical exercise can be increased therefore the selected option is the correct answer.
