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.

Molecular Structure of Ribulose-Bisphosphate
Rating

The process of incorporating carbon dioxide into cell carbon is called carbon fixation. Ribulose bisphosphate is found in the stroma of a chloroplast where the Calvin-Benson cycle takes place. The Calvin-Benson cycle is a carbon fixation pathway in which ribulose bisphosphate plays an important role. Carbon dioxide binds with ribulose bisphosphate and then immediately splits to form two 3-phosphoglycerate molecules (3-carbon compounds) in the presence of an enzyme called Rubisco. The two 3-phosphoglycerate molecules are reduced to glyceraldehyde-3-phosphate; one of which is converted to dihydroxyacetone phosphate, while the other is then combined with dihydroxyacetone phosphate to form fructose-1,6-bisphosphate (a 6-carbon compound). Finally, this product is converted into fructose-6-phosphate. Fructose can be converted into sucrose and is used to synthesize all needed carbon intermediates that produces energy, such as glucose. The rest of the Calvin-Benson cycle involves the regeneration of ribulose bisphosphate, thus completing the cycle.
