Plz, Help :/ you can choose any question you want or all of it if you pleased.

Answer 1

Answer:

29. Proteins support the body's structural framework, chemical reactions, and contractions (muscle movement).

30. Proteins have a primary structure (polypeptide chain of amino acids), secondary structure (made up of alpha helices and beta pleat sheets), tertiary structure (superimposed on secondary structure), and quaternary structure (2 or more polypeptide chains with its own tertiary structure).

31. Protein molecules can denature if conditions aren't right, such as the wrong temperature or pH level. When denatured, proteins typically lose their shape and their function for a short time because their active sites become deactivated (though if conditions are too extreme, they can permanently lose their function). This happens to globular proteins because they are not nearly as stable as fibrous proteins due to their functional 3D shape.

I just did the first 3 since I could easily access the proteins section in my textbook at the moment. :)
