Blood sugar levels are a measure of how effectively the body uses glucose. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise. Islet cells in the pancreas are responsible for releasing both insulin and glucagon. Insulin helps your body turn blood sugar (glucose) into energy. It also helps your body store it in your muscles, fat cells, and liver to use later, when your body needs it. After you eat, your blood sugar (glucose) rises. This rise in glucose triggers your pancreas to release insulin into the bloodstream.

The baker had forgotten to add baking powder. Baking powder is a mixture of baking soda (sodium hydrogencarbonate) and a mild edible acid such as tartaric acid. When this baking powder is added with water, then sodium hydrogencarbonate (NaHCO3) reacts with tartaric acid to evolve carbon dioxide gas. This CO2 gas causes the cake to rise and become soft and spongy.
