During breakdown and synthesis of protein too, respiratory intermediates form the link. Breaking down processes within the living organism is catabolism, and synthesis is anabolism. Because the respiratory pathway (Kreb’s cycle) is involved in both anabolismand catabolism, it would hence be better to consider the respiratory pathway.

Krebs cycle, also known as the citric acid cycle or TCA cycle, is a series of metabolic reactions that occur in the mitochondria of eukaryotic cells. It is an important pathway that produces ATP, the primary source of energy for cellular processes.
Krebs cycle is both catabolic and anabolic because it provides a number of intermediates. Let's understand this in detail.
Catabolic pathway:
Krebs cycle is a catabolic pathway because it breaks down acetyl-CoA, a two-carbon molecule, into carbon dioxide and water. This process releases energy in the form of ATP and NADH. The energy released during this process is used by the cell for various metabolic processes.
Anabolic pathway:
Krebs cycle is an anabolic pathway because it provides a number of intermediates that can be used for the biosynthesis of various biomolecules. These intermediates include oxaloacetate, citrate, alpha-ketoglutarate, succinyl-CoA, fumarate, and malate. These intermediates can be used for the synthesis of amino acids, nucleotides, and other biomolecules.
Importance of intermediates:
The intermediates produced during the Krebs cycle act as important signaling molecules that regulate various cellular processes. For example, citrate is an important regulator of fatty acid metabolism, while succinyl-CoA regulates the synthesis of heme, a component of hemoglobin.
Conclusion:
In summary, the Krebs cycle is both catabolic and anabolic because it breaks down acetyl-CoA to produce energy and also provides important intermediates that can be used for biosynthesis. These intermediates also play a crucial role in regulating various cellular processes.
