The density of cristae is higher in mitochondria of the cell with higher rates of?
ollegr [7]

The density of cristae is higher in the mitochondria of the cell with higher rates of respiration.

The folds found inside the inner mitochondrial membrane are called mitochondrial cristae.

These folds provide a larger surface area where chemical processes, like redox reactions, can occur.

Due to the fact that the ETC enzymes are encased in the inner mitochondrial membrane, an increase in surface area through the production of many cristae may result in higher rates of respiration.

The inner membrane is folded into cristae to boost the mitochondrion's ability to produce ATP.

These folds enable the mitochondrion to contain many more ATP synthase and electron transport chain enzymes.

Hence, the density of cristae is higher in the mitochondria of the cell with higher rates of respiration.
