The correct answer is glucose.
Glucose is the major carbohydrate that can be absorbed and used by humans for energy. In animals, glucose is stored as glycogen in the liver and the muscle tissue in contrast to plants wherein they store glucose as amylose and amylopectin (also known as starch). In digestion of starch, it will start with the saliva where the enzyme salivary amylase will break it down to smaller molecules of starch and limit dextrins. These will be further broken down in the intestines using the pancreatic amylase forming di and trisaccharides. These di and trisaccharides will be metabolized by brush border enzyme to eventually produce glucose (and other monosaccharides that can be absorbed such as fructose and galactose).

Answer AND Explanation:
There is a large number of biochemical reactions taking place in a cell at any given time. Enzymes being biological catalysts control these reactions and regulate them so that they proceed at a pace that is suitable for sustaining life. Thus enzymes regulate cellular activities. Enzymes also ensure that only the required reactions take place and progress to their appropriate extent.
Survival of the strongest... an organisms strength does not affect the natural selection process. Natural selection is adapting the species to be able to better survive in its environment. In order to better survive, an organism does not to be strong. e.g. a plant is probably not a “strong” organism and natural selection doesn’t change that in most cases
