Transports two molecules in different directions
Carbon fixation
the formation of organic molecules from CO2

Metabolic harvesting of energy by oxidation of organic compounds
Chlorophyll a
The main photosynthetic pigment in plants
Cytochrome/b6-f complex
Complex of electron carries that connects the two photosystem in chloroplast
Diffusion
Movement of molecules from high to low concentration
Exergonic
Reactions that release energy
Exocytosis
Discharge of material from vesicles at the cell surface
Facilitated diffusion
Diffusion that is mediated by a membrane protein
