Muscle cells: Muscle cells require a lot of energy to contract and relax, so they have a high number of mitochondria to constantly produce ATP for energy.
Neuron cells: Neuron cells in the brain and nervous system are highly active and require a lot of energy to transmit signals throughout the body. Therefore, they have a high number of mitochondria to support their energy needs.
Heart cells (cardiomyocytes): The heart is a constantly active organ that requires a large amount of energy to pump blood throughout the body. Cardiomyocytes have a high number of mitochondria to support the continuous energy demands of the heart.
