How prokaryotic cells generate energy? if …

Prokaryotes get energy by performing chemical reactions within the cell. ... These electron carriers take the high-energy electrons to a series of membrane proteins to produce more ATP, very similar to what you see in the electron transport chain of cellular respiration in mitochondria.The Ways in Which Prokaryotes Obtain Energy Phototrophs (or phototrophic organisms) obtain their energy from sunlight. Chemotrophs (or chemosynthetic organisms) obtain their energy from chemical compounds. Chemotrophs that can use organic compounds as energy sources are called chemoorganotrophs.Each organelle supports different activities in the cell. Mitochondria, for example, are organelles that provide eukaryotes with most of their energy by producing energy-rich molecules called ATP. Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane.
