Biochemistry courses typically review the general principles of chemistry while simultaneously introducing students to the chemical and molecular events involved in biological processes. Tutors who specialize in this area will help students understand how molecules function and how energy is used. Skills learned in biochemistry may also include cellular chemical reactions, DNA transcription, and helping students identify the relationship of impairment in macromolecular structure and function to disease. Overall, biochemistry tutors will help students understand the intimate specifics of chemistry and biology.
