o 2 during photosynthesis leaves consume carbon dioxide and release oxygen using the enzyme route biscoe but it's not a faster efficient process so up to 50 percent of their conversion efficiency is lost. to a standard car. this colleague elena been sort of our modulating the plant's metabolism to make it easier for their limbs to buy c o 2. they're working with bacteria and synthetic enzymes which are introduced into the plant cells the goal is to slow down foetal respiration process in which c o 2 is released instead of stored or synthetic metabolic cycle will also give the process a boost. in. building 2 things into the plants the synthetic cycle enables them to fix too much better. it's quicker and a larger quantity is stored. the other has to do with photo respiration c o 2 is lost in this process and i can block this undesirable cycle by changing the mix of enzymes so that c o 2 is either not released or is immediately recycled recycling so far these climate friendly plants only exist in the laboratory but thomas dunder car and his doctoral student. have developed a computer model
