Correct Answer: Option 4 carbon dioxide from a mitochondrion carrying out respiration
The illustration showed is a mitochondrion with inner and outer membrane. The inner membrane encloses thee mitochondrial matrix and this is the location where respiration occurs. The arrows represent the ATP produced during respiration.
Photosynthesis occurs in the chloroplasts, not in the mitochondrion. Energy produced in the process cannot be represented by arrows because it is the form of glucose. Therefore, options 2 and 3 are incorrect.
Carbon dioxide is not a form of energy, thus it cannot be represented by the arrows. Option 4 is also incorrect.
