Question

Consider the function of the mitochondria. In what type of cells would you expect a high concentration of mitochondria? (1 point)
• heart cells
• blood cells
• nerve cells
• skin cells

Answer 1

You would expect a high concentration of mitochondria in **heart cells**. Heart cells (cardiomyocytes) require a large amount of energy to continuously contract and pump blood, which is why they contain many mitochondria to meet their high energy demands.
