Continuing Garrett and Grisham’s innovative conceptual and organizing framework, "Essential Questions," BIOCHEMISTRY, 4e, International Edition guides students through course concepts in a way that reveals the beauty and usefulness of biochemistry in the everyday world. The book’s balanced presentation has been streamlined for increased clarity and readability—and to make it more interesting to visual learners, this edition also includes new photos and illustrations that show the subject matter consistently throughout the text. New end-of-chapter problems, MCAT practice questions, and the unparalleled text/media integration with the power of CengageNOW round out this exceptional package, giving students the tools they need to master course concepts and develop critical problem-solving skills they can draw upon long after the course ends.
