The figure below shows an illustration of a mitochondrian. Mustration of a mitochondrion Which of the following best describes the relationship between the structure and function of the mitochondrion? A B с D The shape of the mitochondrion Increases its material-exchange efficiency by maximiz ing its overall volume relative to its surface area. The double-membrane structure of the mitochondrion allows it to maintain its relatively acidic environment in which nutrients can be digested. The folds of the mitochondrion Inner membrane increase its material-exchange effi- ciency by maximizing its surface area relative to its volume. The specific structure of the mitochondrion Inner membrane allows it to correctly guide the folding of proteins into their functional shape.
