Luna, Anika, and Charlotte are studying about carbohydrates in their science class. They learned that sugars are carbohydrates and they looked at a model of a sugar called glucose.

They found out that glucose can be found in foods like honey. Can you help them understand what happens to glucose in the body?

• It goes through a physical change in the cell's nucleus to produce oxygen.

• It uses carbon dioxide in the cell's nucleus to produce a larger sugar molecule.

• It goes through chemical reactions with oxygen, which forms new molecules and provides energy for cells

• It goes through chemical reactions with carbon dioxide, which provides oxygen and energy for cells.
