==========
You're facing a giant bowl of energy packed Carbon Crunchies. One spoonful. Two. Three. Soon, you're powered up by the energy surge that comes from your meal. But how did that energy get into your bowl? Energy exists in the form of sugars made by the plant your cereal came from, like wheat or corn. As you can see, carbon is the chemical backbone, and plants get their fix of it in the form of carbon dioxide, CO2, from the air that we all breath. But how does a plant's energy factory, housed in the stroma of the chloroplast, turn a one carbon gas, like CO2, into a six carbon solid, like glucose? If you're thinking photosynthesis, you're right. But photosynthesis is divided into two steps. The first, which stores energy from the ...
