Answer:
To yield more output
Step-by-step explanation:
The shortcuts in a chemical reaction are used to yield the final output by following a short route rather than the chemically defined long process of production thereby yielding final chemical product in higher amount as the production would become faster.
For example –
If the chemical process in photorespiration is replaced with shortcuts, the chemical products can be recycled very easily at one location instead of following the natural path of processing.
