The principle of conservation of mass is true. For reactants in both open and closed system. When a chemical reaction takes place in an open system. matter can enter from or escape to the surroundings
An agonist exhibit a positive biological effect similar to the receptor it stimulates. For instance, beta agonists (i.e. Salbutamol) stimulate the beta receptors in the bronchial system therefore leading to bronchodialtion. A competitive antagonist negates the function of the specific receptor by binding to the receptor binding site before the biological ligand. A non-competitive agonist negates the function of the specific receptor by binding to an allosteric site leading to a conformational change of the receptor site.
The advantage of a phototropism is that the plants grows in the direction of the sunlight and not into a shadowed direction where it would get less light
Hi;)
Carbohydrates are found on the outer surface of all eukaryotic cell membranes and are attached to mostly the membrane proteins & sometimes phospholipids.
