Do you know any step in the TCA cycle where there is substrate level phosphorylation. Download PDF's. In addition to the two distinct metabolic pathways is the amphibolic pathway, which can be either catabolic or anabolic based on the need for or the availability of energy. Because the respiratory pathway is involved in both anabolism and catabolism, it would hence be better to consider the respiratory pathway as an amphibolic pathway rather than as a catabolic one. The ''intermediate pathway'' in a reaction,when a process is used to form another product in the same process of reaction is called AMPHIBOLISM. So it is better called as an amphibolic pathway. Fats get converted into fatty acids and glycerol whereas fatty acids … NCERT RD Sharma Cengage KC Sinha. 14.4-Amphibolic pathway During aerobic respiration the organic substrates are broken down into simple substances such as carbon dioxide and water (Catabolism). Substances are withdrawn from the respiratory pathway during the synthesis of fats and proteins and are used in anabolism. The pathway is catabolic because in this pathway, glucose is broken down into carbon dioxide and water. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. 9. In other words, why is each part important? 12. Can you think of some other energy carriers present in a cell?
