<span>Glucose which can also be fats from excess carbohydrates.
Carbohydrates actually get stored in the form of long polymers of glucose molecules or as glycogen starch. They provide energy to the animals for performing their daily duties. Carbohydrates are generally considered the fuel for all organisms, and without this most animals would become sloth and would be unable to perform the regular jobs. Carbohydrates are actually very easy to metabolise and hence generate quick energy.<span>

Science cannot prove or refute the existence of God or any other supernatural entity.
Yeast, sugar eating fungus, use oxygen to release the energy from sugar, much like humans, in the process called "respiration". The more sugar there is, the more active the yeast will be and the faster it will grow. Yeast feeds on sucrose, fructose, glucose, and maltose, which it converts to cellular energy through alcoholic fermentation.
Sugar is more suitable for respiration.
The artificial sweeteners are less effective at promoting yeast respiration than sucrose.
