[Maximum number: 2]

Aerobic respiration is made up of several stages.

Write a balanced equation for the complete oxidation of glucose in aerobic respiration.

An answer showing the following steps:

- equation (1)

- balanced equation (1)

accept incorrect formula e.g. CO2 accept correct word equation

e.g. $\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}+6 \mathrm{O}_{2} \rightarrow 6 \mathrm{CO}_{2}+6 \mathrm{H}_{2} \mathrm{O}$ ignore ATP / ADP

1 mark if equation correct but not balanced
