Cellular Respiration and Photosynthesis co-exist as paired processes. Photosynthesis converts light energy into organic molecules such as carbohydrates. These molecules are picked up and utilized as fuel sources in organisms that employ Cellular Respiration for production of ATP and CO2.

1. Create a table comparing and contrasting the two processes.
2. Please provide a hypothesis and suggest an experiment to test the relationship between mtDNA and human ageing. Propose a direction for future research and drug development for targeting mtDNA to combat the aging process.
