“Rubisco has one job. It picks up carbon dioxide from the air, and it uses the carbon to make sugar molecules. It gets the energy to do this from the sun. This is photosynthesis, the process by which plants use sunlight to make food, a foundation of life on Earth. Yay for Rubisco!” That said, it could do better. That’s why Scientists Have ‘Hacked Photosynthesis’ In Search Of More Productive Crops. (My kids think photosynthesis is an Instagram filter.)
