Photosynthesis uses light energy to produce sugar. This sugar is then processed via cellular respiration. The process of photosynthesis occurs in plants and some algae (Kingdom Protista) and takes place in the chloroplast. Photosynthesis combines CO2 and H2O to form sugar. This sugar is then used as fuel via cellular respiration. The reactions involved to [...]

Chlorophyll (Chl) consists of a porphyrin ring with a central magnesium (Mg) atom. It reflects green light, and must be embedded in a membrane to function. Eukaryotes store chlorophyll in the chloroplast. Chloroplasts have 3 membranes and 3 compartments, with thylakoids stacked like pancaked forming grana and stroma. Prokaryotes have chlorophyll in chlorosomes, cytoplasmic membrane [...]
