Answer 2

Answer: The correct answer is X represents water and Z represents oxygen.

Step-by-step explanation:

Cellular respiration is defined as the breaking of sugar into a form that a cell can use as energy. This breaking of glucose takes place in the presence of oxygen gas.

Equation for the cellular respiration is given by the chemical reaction:

`C_6H_(12)O_6+6O_2\rightarrow 6CO_2+6H_2O+Energy`

Here,
`C_6H_(12)O_6` = Glucose

For the given chemical equation in the question,

`Glucose+Z\rightarrow X+Y+Energy`

Z represents oxygen gas

X represents either carbon dioxide or water

Y represents either carbon dioxide or water

Hence, the correct answer is X represents water and Z represents oxygen.
