Question

Consider the activity of the heart relative to other organs, as well as the function of mitochondria. Which of the following statements could you assume to be true?

	a.	cardiac cells have a greater number of mitochondria relative to other cell types
	b.	Cardiac cells have fewer mitochondria relative to other cell types
	c.	All cells have the same number of mitochondria
	d.	Cardiac cells perform fermentation, so mitochondria are not necessary
	e.	Cardiac cells exclusively perform anaerobic metabolism

Answer 1

Option a is correct answer.

Cardiac cells have greater number of mitochondria relative to other cell types.

Explaination.

Cardiac cells have highest number of mitochondria to the range of 2000–5000 per cell, whereas skeletal muscle cell have  50–200 per cell.

As cardiac muscle works continiously to pump blood . they need constant supply of energy which is provided by power house of cell ie mitochondria which are greater in number in cardiac cells .
