Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This 17-minute video lesson provides more detail on the Calvin Cycle and Photorespiration. [Biology playlist: Lesson 32 of 71].

This 13-minute video lesson covers the Calvin Cycle or the light-independent (dark) reactions of photosythesis. [Biology playlist: Lesson 31 of 71].

The dark reactions of photosynthesis (Calvin Cycle) are presented in this learning experience to show where these processes take place in the plant as well as the specific reactions involved.

This NetLogo model of leaf photosynthesis shows the macroscopic outcome of the reaction.

Got oxygen? Got food? Well, then you've got to have photosynthesis! This video will break down photosynthesis into the "photo" part (capturing light energy and storing it) and the "synthesis" part (fixing carbon into carbohydrates). It's all a bit complicated, but take a deep breath and let's find out where that oxygen comes from.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Chloroplast protein of 12 kDa (CP12) participates in the Calvin Benson Bassham (CBB) cycle and many other processes in higher plants, microalgae, and cyanobacteria. The CP12-encoding gene is conserved in many diatoms, but CBB cycle regulation differs between diatoms and other photosynthetic organisms, and CP12 has not been characterized in these ecologically important and evolutionarily complex microalgae. A recent study addressed this knowledge gap by characterizing CP12 in the marine diatom Thalassiosira pseudonana. Using a variety of techniques, researchers found that this CP12 is expressed under both light and dark conditions and throughout growth and that it exhibits some features of intrinsically disordered proteins, like CP12 proteins in other organisms. The protein is an elongated cylinder with kinks and numerous unstable dynamic α-helices. In addition, it exists as a dimer, in contrast to previously characterized monomeric CP12s..."
