Final answer:
The ratio of hydrogen to oxygen in glucose is 2:1.
Step-by-step explanation:
The ratio of hydrogen atoms to oxygen atoms in sugars can vary depending on the specific sugar molecule. However, for the sugar glucose (C6H12O6), which is a common sugar found in the body, the ratio of hydrogen to oxygen is 2:1.
Glucose has 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. This means that for every molecule of glucose, there are 12 hydrogen atoms and 6 oxygen atoms. Therefore, the ratio of hydrogen to oxygen is 2:1.
It's important to note, however, that the ratio of hydrogen to oxygen can vary in other sugars, so it's always necessary to consider the specific sugar molecule being asked about.
