Photosynthesis and Cellular Respiration

1. Create a table comparing anc contrasting the two processes. Include in your comparison variables such as organism type, energy source, cellular location, substrates/reactants/products, full and balanced chemical reation, carrier molecules, and any other parameter you find relevant. 2. 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 ageing. Propose a direction for future research and drug development for targeting mtDNA to combat the ageing process.

I have to come up with a hypothesis and suggest an experiement utilizing mtDNA

I have not clue where to start on this or how to go about it. Apart from its essential role in cellular respiration, the mitochondrion is thought to be implicated in a variety disease states as well as the process of ageing. The mitochondrion contains its own circular DNA molecules (termed mtDNA) which largely encodes for proteins localized to the mitochondrion itself. Please provide a hypotheses and suggest an experiment to test the relationship between mtDNA and human ageing. Propose a direction for research and drug development for targeting mtDNA to combat the ageing process.

One or two structural and functional differences between prokaryotic and eukaryotic cells

Identify and describe one or two structural and functional differences between prokaryotic and eukaryotic cells that you believe contribute to the ability of eukaryotic cells to form the specialized cells and structures found in multicellular organisms. While there are several differences between prokaryotic and eukaryotic cells, please limit your answer to those structural and functional differences that will assist in the evolution of multicellularity.
