Witryna15 wrz 2024 · Feedback inhibition is a normal biochemical process that makes use of noncompetitive inhibitors to control some enzymatic activity. In this process, the final product inhibits the enzyme that catalyzes the first step in a series of reactions. Feedback inhibition is used to regulate the synthesis of many amino acids.

Imbibition is a special type of diffusion that takes place when liquid is absorbed by solids-colloids causing an increase in volume. Water surface potential movement takes place along a concentration gradient; some dry materials absorb water. A gradient between the absorbent and the liquid is essential for imbibition. For a substance to imbibe a liquid, there must first be some attraction between them. Imbibition occurs when a wetting fluid displaces a non-wetting fluid, the … WitrynaAbstract. Water is essential for the rehydration of seeds as the initial step towards germination. The amount of water taken up by an imbibing seed depends upon a number of factors (e.g. size, hydratability of contents, etc.) but in absolute terms it is quite small and often may not exceed 2–3 times the dry weight of the seed. chubb and corvel

WitrynaWhat is imbibition in biology class 11? Imbibition is the process of adsorption of water molecules by the hydrophilic substances. Example- absorption of water by seeds (raisins) and dry wood. Water potential gradient between the absorbent and the liquid imbibed, affinity between the adsorbant and the liquid are necessary for imbibition.
