The correct answer is C. There are 6 atoms of oxygen in a glucose molecule.
A glucose molecule is a simple sugar that is found in the blood and is used by the body for energy. It is a six-carbon sugar, and its chemical formula is C6H12O6. The six carbon atoms are arranged in a ring, and each carbon atom is bonded to one oxygen atom and two hydrogen atoms. The remaining six hydrogen atoms are bonded to the oxygen atoms.
The following is a diagram of a glucose molecule:
The three options that are incorrect are A, B, and D. Option A is incorrect because there are 6 atoms of oxygen in a glucose molecule, not 3. Option B is incorrect because there are 6 atoms of oxygen in a glucose molecule, not 4. Option D is incorrect because there are 6 atoms of oxygen in a glucose molecule, not 10.
