Mitochondria convert chemical energy from the food we eat into an energy … WebDec 1, 2024 · Mitochondria are complex organelles with two membranes. Their architecture is determined by characteristic folds of the inner membrane, termed cristae. Recent studies in yeast and other organisms led to the identification of four major pathways that cooperate to shape cristae membranes.
