How does the glucose we eat influence metabolism?
a. It combines with the glucose we make to form the proteins needed to replace those lost daily in stool.
b. It is composed of extra or "empty" calories that are not necessary for life and only contribute to obesity.
c. It is used inside cells to form the high energy substance adenosine triphosphate (ATP) needed to perform most cell functions.
d. It is converted to fats (lipids) which are used to protect the body from injury, insulate against heat loss, and provide the greatest number of needed calories.
C
Although both proteins and fats can make fuel to run the body's actions, the main fuel provider is carbohydrate. We eat carbohydrates as sugars and starches. Once inside the digestive tract, the body converts most of the carbohydrates we eat into glucose (also called dextrose). Glucose is the most common simple carbohydrate and the main fuel for the human body. Inside cells, glucose is used to form ATP, which is the main chemical energy substance that drives all the body's cellular reactions.
