Question

The diagram below illustrates the structure of glucose. Which of the following describes how the body uses molecules like the one illustrated below? (SC.912.L.18.1)

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

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

Explanation: Cells oxidize glucose through cellular respiration (glycolysis, Krebs cycle, electron transport) to produce ATP, the usable energy currency for cellular processes.
