Concept explainers
To explain: The reason why a liver cell mitochondrion has fewer cristae than a mitochondrion from a heart muscle cell.
Concept introduction: Mitochondrion is the active of oxidative phosphorylation and electron transport chain and found in all eukaryotes. ATP, the source of energy is gained by the oxidative phosphorylation and electron transport chain in mitochondria.

Explanation of Solution
Explanation: The mitochondrion is a cell organelle with outer and inner membrane made of lipid bilayer. The inner membrane projects into the matrix of the mitochondria called as cristae. On the cristae, lie all the complexes involved in electron transport chain. The cristae help to increase the surface area for the proteins. Liver cells require less energy (ATP) than heart cells that constantly are active as part of involuntary functioning. The liver’s function increases only post digestion or when there is a blood glucose alteration level. Therefore, heart muscle cells have more cristae in their inner mitochondrial membrane than liver cells for increased ATP production.
