My first semester bio course is having us practice writing formal lab reports by doing some research through peer reviewed journals our university has access to and citing it in our paper. however something that keeps coming up in the papers i'm reading is something called "the carbon concentrating mechanism." I have no idea what that means. I was wondering if it was in relation to Carbon fixation? my topic is on photosynthesis and respiration in algae and leaf cells. Is it a term that is referring to a cells ability to store carbon dioxide to use so it can later fix it into a sugar molecule ? I only see this used in science journals and nowhere else so im confused. Thank you for your help.
