The body converts all forms of simple sugars into which of the following substances to provide energy to cells?
a. glycogen
b. glucose
c. starch
d. maltose

The answer is B) Glucose.

The main source of energy in the body is carbohydrates, which can be found in various types of food such as meat, vegetables, fruits, etc. Although there are many types of foods that produce carbohydrates, only the staple foods that produce carbohydrates in large quantities. Food that is processed by human organs will be converted into a simpler form called monosaccharides.

These monosaccharides are then absorbed by the body that runs in the blood vessels. When monosaccharides are in the bloodstream they will be referred to as blood sugar or what we often refer to as glucose. In essence, the more sources of carbohydrates eaten, the more glucose will be formed by the body.

Simple carbohydrates like sugar and foods that have a sweet taste are very quickly processed by the body, due to its easy to digest form. This makes sugar the fastest to make glucose because the body only takes less than 15 minutes to produce glucose obtained from foods that contain sugar.

The main carbohydrate or commonly referred to as complex carbohydrates take a long time to become glucose. Types of complex carbohydrate foods with a low glycemic index require as much as 15-30 minutes. This is very different from the type of complex carbohydrate foods with high glycemic levels which only takes about 15 minutes to change shape into blood glucose.
