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.


A metabolic pathway where one reactant in the first reaction is also a product in the final 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.


What does glycolysis breakdown?

Metabolic pathway that converts glucose into pyruvate and a small amount of ATP anaerobicly


What is glycolsis?

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process. It is the first step in cellular respiration and occurs in the cytoplasm of the cell. Glycolysis is a universal pathway found in both aerobic and anaerobic organisms.


What is a catabolic pathway in which organic molecules are broken down to release energy for use by the cell?

Glycolysis is a catabolic pathway in which glucose is broken down in the cytoplasm of the cell to produce ATP and NADH. This process is the first step in cellular respiration and helps generate energy for the cell to use in various metabolic processes.


What do you understand by gly colysis?

Glycolysis is the metabolic pathway that breaks down glucose into pyruvate, generating adenosine triphosphate (ATP) and NADH. It occurs in the cytoplasm of cells and is the first step in both aerobic and anaerobic cellular respiration.


What are the steps of Coagulation pathway?

Blood coagulation can occur either through an intrinsic or extrinsic pathway. The first step in either pathway begins with the production of Factor X,which marks the common pathway of coagulation.


The first pathway of cellular respiration is?

glycolysis.


The first pathway of photosynthesis was?

The first pathway of photosynthesis is the light reaction, which is the absorption of light energy from the sun by the chlorophyll in the plant. The pathway that follows this is the dark reaction or carbon fixation.
