Biochemistry review question V · enzyme

（ I went through the static part of Biochemistry ppt, I just finished watching enzyme today , According to PPT The content sorted out made a little rough review questions ）
（ Why is the number of review questions issued for the first time 5 Well , Because there are four parts of protein, carbohydrate, lipid and nucleic acid in front of me, which are not filled , Whether to fill it or not depends on fate ）
（ I have a plan to review circuit recently , But I have to take the exam this Sunday CET4, I don't know ）

“ Yang Yang Xi and majestic again
Visitors suddenly laugh at me
What you say Anyone can get it
Leave behind The bright moon remembers the past
Warm wine will make friends
Ask the world How many people can know me ”
