A video lesson which introduces students to energy metabolism through the lens of ATP as the primary molecular unit of currency for the cell.
Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.
By the end of this section, you will be able to do the following:
Describe how signaling pathways direct protein expression, cellular metabolism, and cell growth
Identify the function of PKC in signal transduction pathways
Recognize the role of apoptosis in the development and maintenance of a healthy organism
By the end of this section, you will be able to do the following:
Discuss the ways in which carbohydrate metabolic pathways, glycolysis, and the citric acid cycle interrelate with protein and lipid metabolic pathways
Explain why metabolic pathways are not considered closed systems
Build a gene network. The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Explore the effects of mutations within the lac operon by adding or removing genes from the DNA.
