A metabolic pathway that involvs both anabolism and catabolism.
Anaplerotic sequences are metabolic pathways that replenish intermediates in central metabolic cycles, such as the tricarboxylic acid cycle, to maintain metabolic flux. Amphibolic pathways are metabolic pathways that serve both catabolic and anabolic roles, allowing bidirectional flow of metabolites for energy generation and biosynthesis. Together, anaplerotic sequences and amphibolic pathways help regulate metabolism and maintain cellular homeostasis.
Which enzyme is responsible for phosphorylating target proteins in signal transduction pathways? Which second messenger is produced from the cleavage of phosphatidylinositol 4,5-bisphosphate in signal transduction? Which cell surface receptor is involved in the activation of the MAPK signaling pathway? What is the role of G proteins in signal transduction cascades?
You think probable to a reversible reaction.
This type of metabolic pathway is called a cyclic pathway. It involves a series of reactions where the product of one reaction serves as the reactant for another reaction in the pathway, eventually leading back to the initial reactant. One common example is the citric acid (Krebs) cycle in cellular respiration.
The Pathway was created in 2001-04.
The Krebs cycle is an example of an aerobic metabolic pathway, as it requires oxygen to function efficiently.
In aerobic organisms the TCA is amphibolic pathway, one that both srves in the catabolic and anabolic processes. besides its role in the oxidative catabolism of carbohydrates, fatty acids and amino acids, the cycle provides precursors for many biosynthetic pathways

Amphibolic pathways can serve either in energy-yielding catabolic or in energy requiring biosynthetic processes, depending on the cellular circumstances. For example, the citric acid cycle generates NADH and FADH2 when functioning catabolically. But it can also provide precursors for the synthesis of such products as glutamate and aspartate (from a-ketoglutarate and oxaloacetate, respectively), which in turn serve as precursors for other products, such as glutamine, proline, and asparagine

Citrate synthase is inhibited by ATP. Obviously, the Krebs cycle produces ATP. This is the first step and one of the major regulatory steps in the pathway. If the cell has plenty of ATP, then it wouldn't need to keep making it, thus the pathway needs to be shut off. ATP inhibits the enzyme to shut off the pathway. This is an example of feedback inhibition (you can also call it negative inhibition or even product inhibition). Feedback inhibition is when the products of a certain biochemical pathway inhibit earlier enzymes, shutting down the pathway.
