In grammatically correct sentences, explain the role of insulin in maintaining glucose levels after a large meal

After a large meal, the sugar level in our body increases. Insulin helps in reducing or leveling it off. Our cells need sugar for energy, but sugar in the blood is not readily accessible by cells. Release of insulin from the pancreas assists the sugars in entering the cells. If there is an excess in sugar, insulin also helps in storing the excess in the liver until it is needed by the body.
