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:
Discuss the importance of electrons in the transfer of energy in living systems
Explain how ATP is used by cells as an energy source
By the end of this section, you will be able to do the following:
Explain ATP's role as the cellular energy currency
Describe how energy releases through ATP hydrolysis
By the end of this section, you will be able to do the following:
Explain how plants absorb energy from sunlight
Describe short and long wavelengths of light
Describe how and where photosynthesis takes place within a plant
Video lecture focuses on light-dependent reactions and how they work. It shows how light energy can excite electrons which can be used to create ATP and NADPH. [9:04]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
This pathways explores how cells harvest energy using cellular respiration in eukaryotic cells and photosynthesis in plant cells.
A video introducing the two different processes of metabolism: catabolism and anabolism. Video gives lots of example to explain that catabolism is a process of breaking down and anabolism rebuilds matter. [10:06]

Understand the structure and function of the powerhouse of the cell, the mitochondria. [2:40]
Discover how mitochondrial DNA (mtDNA) is inherited, and complete a pedigree chart by determining which individuals might share mtDNA with an unknown ancestor.
This pathway provides an introduction to cellular metabolism, including a comparison of the processes of photosynthesis and cellular respiration. For a deeper look at this topic, we recommend the pathways Metabolism, Cellular Respiration and The Biological Process of Photosynthesis from the OpenStax textbook Biology for AP® Courses.
Students learn about the basic principles of electromicrobiology—the study of microorganisms’ electrical properties—and the potential that these microorganisms may have as a next-generation source of sustainable energy. They are introduced to one such promising source: microbial fuel cells (MFCs). Using the metabolisms of microbes to generate electrical current, MFCs can harvest bioelectricity, or energy, from the processes of photosynthesis and cellular respiration. Students learn about the basics of MFCs and how they function as well as the chemical processes of photosynthesis and cellular respiration
This video segment describes the critical role that mitochondria play in nearly every cellular process in your body.
Page describes Photosynthesis in great detail. Provides an extensive amount of links on all different aspects of photosynthesis. Very thourough.
