Question

9 which cells would need more mitochondria from the choices and descriptions below? a fat cells and skin cells need the most energy and would need more mitochondria b fat cells and skin cells dont need much energy and would need more mitochondria c muscle and brain cells dont require much energy and wouldnt need mitochondria d muscle and brain cells require the most energy and would need more mitochondria

Explanation:

Mitochondria are the powerhouses of the cell, generating ATP (energy). Muscle cells (for movement - contraction/relaxation) and brain cells (for neural signaling, synaptic activity, etc.) have high - energy demands. Fat cells store energy (as fat) and skin cells (for protection, some barrier functions) have relatively lower energy requirements compared to muscle and brain cells.

Answer:

D. Muscle and brain cells require the most energy and would need more mitochondria
