Multiple Choice
In the human body, which cell type would typically contain the greatest number of mitochondria due to its high and continuous ATP demand?
A
Adipocytes (fat cells)
B
Red blood cells (erythrocytes)
C
Goblet cells of the intestinal epithelium
D
Cardiac muscle cells (cardiomyocytes)
Verified step by step guidance1
Understand the role of mitochondria: Mitochondria are the organelles responsible for producing ATP through cellular respiration, which is essential for energy-demanding processes in cells.
Identify the energy demands of each cell type: Consider which cells require continuous and high amounts of ATP. For example, adipocytes store energy, red blood cells lack mitochondria, and goblet cells secrete mucus but do not have extremely high energy needs.
Recall that cardiac muscle cells (cardiomyocytes) contract continuously to pump blood throughout the body, requiring a constant and large supply of ATP.
Recognize that due to this high and continuous ATP demand, cardiomyocytes contain a greater number of mitochondria compared to other cell types to meet their energy needs.
Conclude that the cell type with the greatest number of mitochondria is the cardiac muscle cell, as it must sustain continuous contraction and energy production.
