RuBP oxygenase-carboxylase (rubisco), a key enzyme in photosynthesis, is the molecular equivalent of a good friend with a bad habit. In the process of carbon fixation, rubisco incorporates carbon dioxide (\text{CO}_2CO2) into an organic molecule during the first stage of the Calvin cycle. Rubisco is so important to plants that it makes up 30\%%30%% or more of the soluble protein in a typical plant leaf^11. But rubisco also has a major flaw: instead of always using \text{CO}_2CO2 as a substrate, it sometimes picks up \text O_2O2 instead.This side reaction initiates a pathway called photorespiration, which, rather than fixing carbon, actually leads to the loss of already-fixed carbon as \text{CO}_2CO2. Photorespiration wastes energy and decreases sugar synthesis, so when rubisco initiates this pathway, it's committing a serious molecular faux pas.

Reactive oxygen species can have detrimental effects on sports turf. This book describes the causes of reactive oxygen species, its photosynthetic targets, and nutrients and compounds that can manage and prevent them.

As sports turf managers we love green aesthetically pleasing turf. Chlorophyll is a key component in photosynthesis, however, certain events can disrupt it's development. This book elaborates on proper chlorophyll development and methods to help prevent it's breakdown.
