Why is it difficult for oxygen to reach the mitochondria in a large cell?

• The mitochondria are located in the center of the cell

• The cell membrane is too thick

• The oxygen cannot diffuse through the cell membrane

• The diffusion process takes a long time

Why do elephants have a slower metabolic rate compared to mice?

• Because elephants have a larger surface area to volume ratio

• Because elephants have a smaller surface area to volume ratio

• Because mice have a larger surface area to volume ratio

• Because mice have a smaller surface area to volume ratio
