Type of coupling reaction
I would want to be at the beach during the spring.
Answer:
<h2>4</h2>
Explanation:
1. Photorespiration occurs in plants and it is a wasteful pathway, it competes with the Calvin cycle. It begins when rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase (RUBISCO) catalyzes both CO2 and O2 fixation) acts on O₂ instead of CO₂.
2. Photorespiration is initiated by the oxygenase activity of rubisco, the same enzyme that is also responsible for CO2 fixation.
3. Phosphoglycolate formed by O₂ fixation is recycled to the Calvin cycle intermediate phosphoglycerate in the photorespiratory pathway.
4. During oxygen fixation,1 molecule of PGA and 1 molecule of 2-phosphoglycolate are formed. The 2-phosphoglycolate is converted back to PGA in the photorespiratory cycle.
The chemical equation needs to be balancedso that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error. hope this helps
