Answer:
Option 2, Injection into a large muscle with the use of the Z-track method
Explanation:
The z-track method is used for parenteral iron preparations to avoid tissues from staining and irritation over the air lock method. Z track method prevents the leakage of medicine beneath the skin. In this method, after injecting the medicine the muscle and skin is pulled first and the injection is pulled later. This forms zigzag line that prevents medicine from leaking. Generally injected at thighs and buttocks
Hence, option 2 is correct
Due to the absorption of energy when chemical bonds are broken, and the release of energy when chemical bonds are formed, chemical reactions almost always involve a change in energy between products and reactants.
Hope this helps
Enzyme function is influenced by physical and chemical environment factors such as pH and temperature.
-Enzymes may require a nonprotein cofactor or ion for catalysis to take place.
-Enzymes increase the rate of chemical reaction by lowering activation energy barriers.
