Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis (Figure below) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.
In hemophilia A it’s caused by a mutation in the gene for factor VIII. Hemophilia B is a result in a deficiency in factor IX due to a mutation in its corresponding gene.
In both cases, it is a mutation in the DNA (the macromolecule).
