In the 1960s, two Australian scientists, M.D. Hatch and C.R. Slack described a new pathway for carbon fixation in photosynthesis. The Hatch-Slack pathway describes a biochemical system in which carbon is first incorporated into the four-carbon...

The leaves of green plants using the C4 or Hatch-Slack pathway for photosynthetic carbon fixation almost invariably have a specialized internal arrangement of cells surrounding the vascular bundles that is called Kranz anatomy. Kranz, the German word...

C4 carbon fixation is one of three biochemical mechanisms, along with C3 and CAM photosynthesis, functioning in land plants to "fix" carbon dioxide (binding the gaseous molecules to dissolved compounds inside the plant) for sugar production through...

As biology teachers and professors, we aim to prepare our students to think critically and analytically, and to provide a set of conceptual and practical skills the students will need to continue their education in biology during and after their college years. Another of...

The role of a C^sub 4^ pathway in photosynthetic carbon fixation by marine diatoms is presently debated. Previous labeling studies have shown the transfer of photosynthetically fixed carbon through a C^sub 4^ pathway and recent genomic data provide evidence for the existence of key...
