Rubisco in C3 Plants, 2-Phosphoglycolate, and Photorespiration

The video tutorial explains the role of Rubisco in photosynthesis, focusing on C3 plants. It details the dual activity of Rubisco, which can lead to the production of a wasteful byproduct, 2-phosphoglycolate, through oxygenation. The process of photorespiration is described as a necessary but energetically costly pathway to recycle this byproduct. The video also compares C3 plants with C4 and CAM plants, highlighting their strategies to avoid the inefficiencies of photorespiration.

How does the oxygenase activity of Rubisco affect the efficiency of C3 plants?

What are the energetic costs associated with the photorespiration pathway in C3 plants?

In what ways do C4 and CAM plants mitigate the effects of oxygenase activity in Rubisco?
