Multiple Choice
Which type of human cell typically contains the highest number of mitochondria due to exceptionally high ATP demand?
A
Goblet cells of the intestinal epithelium
B
Cardiac muscle cells (cardiomyocytes)
C
Red blood cells (erythrocytes)
D
Adipocytes (fat cells)
Verified step by step guidance1
Understand the role of mitochondria: Mitochondria are the organelles responsible for producing ATP, the energy currency of the cell, through cellular respiration.
Identify cells with high energy demands: Cells that require a lot of energy to perform their functions typically contain more mitochondria to meet this demand.
Evaluate each cell type: Goblet cells secrete mucus, red blood cells transport oxygen but lack mitochondria, adipocytes store fat and have moderate energy needs, while cardiac muscle cells continuously contract and require a large amount of ATP.
Recognize that cardiac muscle cells (cardiomyocytes) have exceptionally high ATP demand due to their constant activity in pumping blood throughout the body.
Conclude that cardiac muscle cells contain the highest number of mitochondria among the options given to sustain their high energy requirements.
