alleryIn mitochondria, the increase in surface area for the respiratory enzymes is achieved by
AStroma of the matrix
BLumen of the thylakoid
CCristae of the outer membrane
DCristae of the inner membrane
Answer & Solution
Correct answer: D. Cristae of the inner membrane
The INNER mitochondrial membrane folds into cristae, dramatically increasing the surface area available for electron-transport chain enzymes.
The outer membrane is smooth
stroma and thylakoid lumen are chloroplast features.
