In the citric acid cycle, what does the atp do?

ATP acts as a regulatory molecule in multiple steps of the citric acid cycle:

Explanation:

In the citric acid cycle, the 2 pyruvate molecules formed can either be converted to Acetyl Co-A or stored as lipids. As the enzyme, pyruvate dehydrogenase has to make this decision, this step of the TCA cycle is a crucial control point of the pathway. Pyruvate dehydrogenase is activated when phophorylated by a kinase but deactivated in the presence of high amount of ATP by a phosphatase enzyme. On the contrary, the presence of high ADP activates the complex.

ADP or a low energy signal allosterically activates the isocitrate dehydrogenase that converts isocitrate to a five carbon alpha-ketoglutarate. High ATP inhibits the enzyme.

The enzyme, α-ketoglutarate dehydrogenase converts alpha ketoglutarate to a four carbon compound, succinyl Co-A. Here, ATP also acts as an inhibitor.

explanation:

clinically, some people often have repeated allergies, eczema and respiratory infections or other parts of the infection, in this case, in addition to some routine tests such as tests for white blood cells, immunoglobulin series, lymphocyte subsets, etc., the five immune immunoglobulin tests are also necessary.
