Binding of a regulatory molecule changes the shape of the enzyme?

When a regulatory molecule binds to an enzyme, it can cause a conformational change in the enzyme's active site, either activating or inhibiting its function. This change in shape can affect the enzyme's ability to bind substrate molecules and catalyze reactions. Regulatory molecules can help control enzyme activity in response to cellular signals or changes in the environment.


What regulatory proteins can be found on an actin molecule?

Tropomyosin and troponin are the regulatory proteins found on an actin molecule in muscle cells. Tropomyosin regulates the interaction between actin and myosin, while troponin helps in controlling muscle contraction by modulating the position of tropomyosin on the actin filament.


How does the allosteric enzyme curve illustrate the relationship between enzyme activity and the binding of regulatory molecules?

The allosteric enzyme curve shows how enzyme activity changes when regulatory molecules bind to the enzyme. This curve demonstrates that the binding of regulatory molecules can either increase or decrease enzyme activity, depending on the specific enzyme and regulatory molecule involved.

What is a regulatory board?

A regulatory agency (also regulatory authority, regulatory body or regulator) is a public authority or government agency responsible for exercising autonomous authority over some area of human activity in a regulatory or supervisory capacity. An independent regulatory agency is a regulatory agency that is independent from other branches or arms of the government.


A common polar molecule in living organisms is what?

Water is a common polar molecule in living organisms. Its polarity is due to an unequal sharing of electrons between the hydrogen and oxygen atoms, making it essential for many biological processes such as hydration, transport of nutrients, and regulatory functions within cells.


What molecule causes transcription of an operon?

The molecule that typically causes transcription of an operon is an inducer, which can either activate or repress the operon by binding to a regulatory protein. In the case of an inducible operon like the lac operon in E. coli, lactose acts as an inducer by binding to the repressor protein and preventing it from blocking transcription.

What is an excess of end-product molecule alters the shape of the first enzyme in the pathway and shuts off that metabolic pathway?

The phenomenon you are describing is known as "feedback inhibition." In this regulatory mechanism, an excess of the end-product molecule binds to an allosteric site on the first enzyme of the metabolic pathway, causing a conformational change that reduces the enzyme's activity. This effectively shuts off the pathway, preventing the overproduction of the end product and ensuring metabolic balance within the cell. Feedback inhibition is a crucial regulatory strategy in biochemical pathways.
