3 Chemistry concepts behind baking a CAKE Part-3

Exothermic and endothermic reactions go hand in hand with heat. An exothermic reaction is when energy (heat) is released while endothermic is the opposite; an endothermic reaction takes in energy. And in the example of baking a cake, the reaction that is taken is an endothermic reaction; this makes the cake batter to bake. The eggs in the cake are also impacted, the heat causes the protein from the eggs to change and make the cake firm. Also, many types of cake recipes require a few common ingredients, such as yeast and sugar. “Yeast is a type of fungi that is able to convert the sugar you add into ethanol and carbon dioxide through what is known as a metabolic pathway.” Which basically means the yeast changes the sugar. You may also notice tiny bubbles in your cake; heat helps baking powder produce tiny bubbles of gas, which then leads to a fluffy cake.
