Which of the following types of enzymes is responsible for joining molecules by forming new chemical bonds?

What is the name of the class of enzymes that permit a phospholipid in the cellular membrane to move from facing the exoplasm (outside of the cell) to the cytosol (cellular interior)?

Chymostrypsin cleaves a polypeptide into two smaller subunits by using water in order to make the new amino and carboxyl termini. Based on this mechanism, what type of enzyme is chymostrypsin?

Which of the following are not enzymes that act on DNA?

During glycolysis, glucose-6-phospate is rearranged in order to form fructose-6 phosphate. The enzyme that accomplishes this does not change the intermediate's chemical formula in any way, but simply alters the shape of the molecule.

Based on this action, what type of enzyme is involved in this step in glycolysis?

Which of the following is not a class of enzymes that alter epigenetic states?
