1. Light Reactions: Also known as the light-dependent reactions, this stage of photosynthesis occurs in the thylakoid membranes of the chloroplast. Light energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH.
2. Calvin Cycle: Also known as the light-independent reactions, this stage of photosynthesis occurs in the stroma of the chloroplast. Carbon dioxide is fixed and converted into glucose using the ATP and NADPH produced in the light reactions.
Overall, photosynthesis involves the conversion of light energy into chemical energy (ATP and NADPH) and the conversion of carbon dioxide into glucose, a process that sustains life on Earth by providing food and oxygen for plants and other organisms.
