Question 13

Malic acid is an organic acid that can be accumulated in vacuoles and utilized as a respiratory substrate in plant cells.

The chemical equation for the complete oxidation of malic acid is:

C4H6O5+3 O2→4 CO2+3 H2O \text{C}_4\text{H}_6\text{O}_5 + 3\text{ O}_2 \rightarrow 4\text{ CO}_2 + 3\text{ H}_2\text{O} C4​H6​O5​+3 O2​→4 CO2​+3 H2​O

What is the respiratory quotient (RQ) of malic acid?
