Nzymes of glycolytic pathway control the flight performance of fly

This is the paper that describes the one research paper.
I should first introduce the topic of this and in the body I should write if the paper is using scientific method correctly. So when you read the paper you will see the scientific method in the body part. If you see some unclear structure of the paragraph you can correct it.
I want you to correct unclear expression that confuses the reader. I also have some grammatical problem.
