partition coefficient

by حلا خالد محمود صالح _ - Monday, 21 February 2022, 10:02 PM

It is a method by which the polarity of a solute can be measured by the ratio of its solubility in an organic solvent to its solubility in water

In general, the higher the non-polar (hydrophobic) material, the higher the partition coefficient

Ping-pong mechanism, also called a double-displacement reaction, is characterized by the change of the enzyme into an intermediate form when the first substrate to product reaction occurs

Plasmolysis

if the plant is not watered, the extracellular fluid will become hypertonic, causing water to leave the cell . In this condition, the cell does not shrink because the cell wall is not flexible. However, the cell membrane detaches from the wall and constricts the cytoplasm. This is called plasmolysis. Plants lose turgor pressure in this condition and wilt
