Your body uses fats as a supply and store of energy: a gram of fat contains more than double the amount of energy present in a gram of carbohydrate. The steroids in your body include some hormones. Other lipids make up the outer layer of all your cells, and the fatty sheaths that insulate nerve fibres.
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
Answer:
The enzyme Topoisomerase functions to prevent super-coiling of the DNA molecule during replication.
Explanation:
- During replication, topoisomerases are required to relieve the positive supercoiling that arises from DNA unwiding mediated by Helicases.
- A DNA topoisomerase is a nuclease that breaks a phosphodiester bond in a DNA strand.
- All topoiomereases are classified as Topoisomerase I and Topoisomerase II depending on whether they cleave one or two strands respectively.
- Topoisomerase I do not use ATP as a source of energy, the reaction is powered by energy stored in super-coiled DNA.
- Topoisomerase II also do not require external energy but it utilizes ATP hydrolysis to drive conformation changes in the protein during reaction cycle.
