What causes reversal of biochemical reactions?
Alexxandr [17]

A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from reversible process in thermodynamics.

Weak acids and bases undertake reversible reactions. For example, carbonic acid: H2CO3 (l) + H2O(l) ⇌ HCO−3 (aq) + H3O+(aq).

The concentrations of reactants and products in an equilibrium mixture are determined by the analytical concentrations of the reagents (A and B or C and D) and the equilibrium constant, K. The magnitude of the equilibrium constant depends on the Gibbs free energy change for the reaction.[2] So, when the free energy change is large (more than about 30 kJ mol−1), then the equilibrium constant is large (log K > 3) and the concentrations of the reactants at equilibrium are very small. Such a reaction is sometimes considered to be an irreversible reaction, although in reality small amounts of the reactants are still expected to be present in the reacting system. A truly irreversible chemical reaction is usually achieved when one of the products exits the reacting system, for example, as does carbon dioxide (volatile) in the reaction

expeople1 [14]

Answer:

binding of the hormone molecule with its receptor of the cell.

Explanation:

Hormones are chemical messengers secreted or released by endocrine glands to effect a response in another location called target location. Hormones are proteinous molecules and like every other protein, its function is determined by its shape.

Hormones function or effect their changes by binding to the receptor of the target cell. The hormone recognizes and will only bind to its own receptor molecule on its target cell on order to bring about any change. This defines the specificity of the hormone.
