At room temperature or about 25°C, potassium nitrate (KNO₃) has a solubility of about 38.7 grams per 100 mL of water. At this concentration, the KNO₃ solution is said to be saturated since it already contains the maximum amount of solute that the solvent can dissolve, thus, if you add more KNO₃ salt, it will no longer dissolve. When the solution has less solute than that of the saturation concentration, it is called an unsaturated solution, thus if you add more solute, the KNO₃ salt will still dissolve. If the concentration of the solution is greater than its solubility, the solution is said to be supersaturated, thus, if excess KNO₃ salt is added, crystals will start to form.

PLEASE HELPPPPPPPPPP!!!!!!! Explain how ATP and ADP act as allosteric regulators of enzymes that are responsible for ATP product
lozanna [386]

Answer:

The molecules that bind cellular respiration enzymes act as signals, giving the enzyme information about the cell's energy state. ATP and ADP are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a "stop" signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration.

This is a case of feedback inhibition in which a product feeds back to shut down its pathways.
