Essay question 6 6)a) Draw the structure of a mitochondrion as seen in an electron micrograph.[5] B) Describe the central role of acetyl (ethanoyl) CoA in carbohydrate & fat metabolism.[5] Acetyl CoA is formed in both carbohydrate and fat metabolism. In carbohydrate metabolism, Acetyl CoA links glycolysis and the Krebs's cycle in a link reaction, in the link reaction carbohydrates or glucose is converted into pyruvic acid and from that into Acetyl CoA. In fat metabolism, the Acetyl CoA is formed from fats, the fats breakdown into glycerol and fatty acids. The fatty acids are then oxidized to form Acetyl CoA. The carrier CoA accepts acetyl groups produced in both metabolisms and brings them to be used in the Krebs cycle. c) Discuss the importance of a balanced diet for people with varying energy needs.
