ATP drives a variety of growth and development of the plant By product reaction are CO2 and Water Less efficient form of respiration Does Used not require oxygen in soil and water where oxygen is in short supply Some bacteria and fungi adapted to anaerobic respiration covert energy by fermentation Produces ethyl alcohol and lactic acid Human recognized the value of fermentation in the making of silage, beer, and wine. Plant growth takes place primarily at night when photosynthesis is shut down. Fueled by aerobic respiration. 1. 2. 3. 4. Glycolysis Acetyl CoA Citric Acid cycle (Kreb’s Cycle) Electron transport chain Glycolysis Acetyl Coenzyme A Citric Acid Cycle - through the first 3 steps, hydrogen atoms were transferred to hydrogen acceptors NAD and FAD, forming NADH and FADH2 Aerobic respiration, these reduced compounds enter the electron transport system Series of chemical reactions by which electrons are passed from one acceptor molecule to another. Oxygen During is the final hydrogen acceptor. this pathway, ATP is synthesized by the process of chemiosmosis. The process in which hydrogen atoms cross the thylakoid membrane and travel down a protein gradient, producing ATP, This 4th stage see the production of 32 ATP molecules.
