Final answer:
Glucose, a monosaccharide sugar with the molecular formula C6H12O6, is made up of carbon, hydrogen, and oxygen. The elements potassium, iron, and bromine are not components of glucose. 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms comprise one molecule of glucose, which is a primary energy source for living organisms.
Step-by-step explanation:
The different elements that make up a molecule of glucose are oxygen, hydrogen, and carbon. The chemical formula for one molecule of glucose is C6H12O6, indicating the presence of carbon (C), hydrogen (H), and oxygen (O) atoms. The other elements listed, such as potassium, iron, and bromine, are not found in the glucose molecule.
From the chemical formula C6H12O6, it is clear that the molecule consists of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. This composition corresponds to a monosaccharide sugar and is fundamental to the biochemical processes of living organisms, serving as a primary energy source.
The empirical formula of glucose, which represents the simplest whole-number ratio of the elements, is CH2O. However, since glucose has 6 carbon atoms, the molecular formula is expressed as C6H12O6 to account for the actual number of atoms in the molecule.
