Question

Identify one type of animal cell that typically contains large numbers of mitochondria. Support your answer

Answer 1

In humans, the oocyte or egg contains the most mitochondria. But, since it is the largest cell in the body, the number of mitochondria is relative to its size.

Step-by-step explanation:

• A typical animal cell contains about 1000 to 2000 mitochondria per cell.
• Muscle cells, particularly, cardiac muscles require a lot energy as they are constantly contacting and relaxing. Muscle cells have about 5000 mitochondria per cell.
• The egg, being the largest cell in the body, has the highest number of mitochondria compared to any cell. The oocyte has about 100,000 to 600,000 mitochondria per cell with each mitochondrion containing one copy of the mitochondrial DNA (mtDNA).
