Answer 2

Number of hydrogen atoms in glucose

Step-by-step explanation:

The correct option would be number of hydrogen atoms in glucose.

From the balanced equation of cellular respiration below:

`C_6H_(12)O_6 + 6O_2 --> 6CO_2 + 6H_2O`

There are 12 atoms of hydrogen in the water molecules produced just as there are 12 atoms of hydrogen in glucose (
`C_6H_(12)O_6`).

There are no hydrogen atoms in carbon dioxide.

The addition of hydrogen atom in the simplest sugar and hydrogen gas is 14, rather than 12.

There are no hydrogen gas in carbon dioxide and oxygen.

Hence, the correct option is number of hydrogen atoms in glucose.
