Homework Answers
Methanogens are types of organisms, classified as archaea, that exhibit the ability to produce methane as a metabolic byproduct. Methanogens present in non aerobic conditions, are able to use carbon dioxide as a source of carbon for growth. In addition, the carbon dioxide is used as an electron acceptor in the production of methane. Methanogens are able to utilize the acetyl-CoA pathway to fix carbon dioxide.

Starting with Acetyl-CoA in the mitochondrial matrix, show how a molecule of acetyl-CoA may get incorporated into a molecule of phosphatyidylserine in the plasma membrane. You should summarize the pathways involved into the critical steps involved. You do NOT need to show every reaction and/or enzyme. You can present your summarizing note in any form like a table, diagram, or outline, do NOT describe it in just words. Your pathway should have a minimum of six steps. Label at least...
