Sugars form carbohydrates, which are linked together to form fats that store energy.
Carbohydrates are broken down into glucose, which is stored inside the body’s cells.
Sugars are broken down into proteins that become the building blocks of the body’s tissues.
Carbohydrates, such as glucose, are broken down to release chemical energy that is used by the body’s cells.

Answer 1

Correct answer: "Carbohydrates, such as glucose, are broken down to release chemical energy that is used by the body’s cells."

Explanation: Cells break down glucose during cellular respiration (mainly in mitochondria) to produce ATP, the chemical energy cells use to power processes. Excess glucose can be stored as glycogen or converted to fat.
