How does ammonia inhibit photosynthesis
WebDetermination of such a quantum yield indicates how efficiently the photochemistry is performed versus all other deexcitation processes. For instance, the photochemical reactions of photosynthesis can be decreased by environmental stresses such as freezing temperatures, excessive light, and drought, leading to a decrease in Φ photochem (Eq. … WebNitrogen-fixing bacteria (in the soil and within the root nodules of some plants) convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to …
