Which of the following is true of bothmitochondria and chloroplasts?(A) They are found in the cells of eukaryoticautotrophs and heterotrophs.(B) They include stacks of membranes thatabsorb light.(C) They include compartments where hydrogenions are concentrated.(D) They produce sugars using energy harvestedin the cytoplasm.(E) They break down sugar to produce ATP

The correct answer is (C) They include compartments where hydrogen ions are concentrated.

Here's why:

(A) Mitochondria are found in both autotrophs and heterotrophs, but chloroplasts are only found in autotrophs (organisms that can produce their own food).

(B) Chloroplasts include stacks of membranes that absorb light, known as thylakoids. However, mitochondria do not have these structures.

(C) Both mitochondria and chloroplasts have compartments where hydrogen ions are concentrated. In mitochondria, this is the intermembrane space. In chloroplasts, this is the thylakoid space. This concentration of hydrogen ions is used to generate ATP.

(D) Neither mitochondria nor chloroplasts produce sugars using energy harvested in the cytoplasm. Chloroplasts produce sugars using energy from sunlight in a process called photosynthesis. Mitochondria produce ATP from glucose in a process called cellular respiration.

(E) Mitochondria break down sugar to produce ATP in a process called cellular respiration. However, chloroplasts do not break down sugar to produce ATP. Instead, they produce sugar from carbon dioxide and water using energy from sunlight.
