Sunlight plays a much larger role in our sustenance than we may expect: all the food we eat and all the fossil fuel we use is a product of photosynthesis, which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms, ranging from plants to bacteria. The best known form of photosynthesis is the one carried out by higher plants and algae, as well as by cyanobacteria and their relatives, which are responsible for a ...

Cellular Respiration and Photosynthesis Question

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.

Although it appears that Photosynthesis has preceded Cellular Respiration by billions of years, the processes share many structural features. Utilize the library, Internet, and any other resources available to complete the following:

Create a table comparing and contrasting the two processes. Include in your comparison variables such as organism type, energy source, cellular location, substrates/reactants/products, full and balanced chemical reaction, carrier molecules, and any other parameter you find relevant.

Apart from its essential role in cellular respiration, the mitochondrion is thought to be implicated in a variety of disease states as well as the process of aging. The mitochondrion contains its own circular DNA molecule(s) (termed mtDNA) which largely encodes for proteins localized to the mitochondrion itself. Please provide a hypothesis and suggest an experiment to test the relationship between mtDNA and human aging. Propose a direction for future research and drug development for targeting mtDNA to combat the ageing process.

Please submit your assignment.
