The remaining glucose is converted to fat and stored into the body as an energy source.
Glucose is a sugar molecule which can be converted into two three-carbon pyruvate molecules through the process of glycolysis and then into acetyl CoA. So, when the body requires immediate energy, acetyl CoA enters the Citric Acid Cycle (Krebs cycle) and ATP is formed. But, when glucose intake exceeds your body's energy needs, acetyl CoA begins the process of fatty acid synthesis (FFA). FFAs become triglycerides that are stored in the fat tissues of the body which can be broken down later to give the energy the body needs.
The predominant hypothesis for why the animals needed some 3 billion years to evolve after the life first appeared on the planet is that the conditions were not right for them to appear.
The life on Earth has appeared much earlier that what we normally assume, and also it has not been evolving very quickly, but instead it has been a very slow and gradual process. The reason for that is that the living conditions on the Earth were much different than what are they now, or anytime from the Cambrian period until the present.
The surface was still pretty hot, and there was intense volcanic activity. The composition of the atmosphere was not suitable for animals to appear at all, and in fact it would have been toxic for them. The water too had chemicals in it that were not providing the right conditions for animals to evolve. It was only after the plants started to appear and managed to make lot of changes in the water, atmosphere, and land, than the animals were able to evolve and develop.
