What form must all carbohydrates be in for cells to use them as an energy source?
-
Fructose
-
Glucose
-
Glycogen
-
Insulin
That's Correct!
It's Wrong!
Glucose is the correct answer because it is the form in which carbohydrates need to be in for cells to use them as an energy source. Glucose is a simple sugar that can be easily broken down and metabolized by cells through a process called cellular respiration. Once glucose is absorbed into the bloodstream, it can be transported to cells and used as a primary source of energy. Other forms of carbohydrates, such as fructose and glycogen, need to be converted into glucose before they can be utilized by cells for energy. Insulin is a hormone that helps regulate blood sugar levels, but it is not a form of carbohydrate.
