In biological processes the direction an ion will move by diffusion or active transport across membrane is determined by the electrochemical gradient. In mitochondria and chloroplasts, proton gradients are used to generate a chemiosmotic potential that is also known as a proton motive force.
some bacteria can absorb N2 and convert it to ammonia, nitrates, and nitrites Describe the relationship between Rhizobia and legumes. Rhizobia are bacteria that are found in nodules in roots of legumes, provide the plant ammonia in return for protection and sugar How do nitrogen-fixing bacteria colonize root plants? 1. recognition of bacteria and plant (plant releases flavenoids, bacteria produce Nod factors) 2. Nod factors bind to root-hair surface, rhizobia multiply 3. Rhizobia enter epidermal cell through infection thread 4. once invading root cortex, infection thread bursts and releases rhizobia into cortex cells
