Would elevated co2 levels affect photosynthesis or respiration more, and how?

Question

I need help with this please!!

Answer 1

Photosynthesis is a process which occurs in plants; it’s basically the production of oxygen (O2).   

This is the equation (reaction): 6CO2 + 6H20 + Energy (sunlight)  -----> C6H1206 + 6O2 

 

According to Le Chatelier’s Principle (taught in Chemistry), if you increase the concentration of a reactant or product, this is increasing the stress of the reaction. So, the system reacts in a way to decrease the stress and stabilize the reaction. For example, if you increase CO2 (a reactant) in the above equation, the reaction would shift to the right, increasing the release of products (glucose and oxygen) and decreasing the release of carbon dioxide. If we were to add more products, in which direction would the reaction shift, right or left? 

 

Respiration is just the medical term used to describe the process of breathing. In such a process, we inhale O2 and exhale CO2. If the air quality saw an increase in carbon dioxide, would it be easier to breathe? (Think of mountain climbing)
