Aerobic respiration, after glycolysis, occurs in the mitochondria of eukaryotes and cytoplasm of prokaryotes. Cellular respiration begins when electrons are transferred from NADH and FADH 2 —made in glycolysis, the transition reaction, and the Krebs cycle—through a series of chemical reactions to a final inorganic electron acceptor (either oxygen in aerobic respiration or non-oxygen inorganic molecules in anaerobic respiration). where the first set of reduced coenzymes are produced, 2 NADH produced.

Respiration is a series of chemical reactions, but this equation summarises the overall process. 1. pyruvate gets transported into the mitochondria. It’s formed from ADP (Adenosine diphosphate) + Pι and consists of a ribose sugar, a nitrogenous base (adenine) and three phosphate groups each carrying a negative charge. 1. He starts with a brief description of the two processes. The by-product of this process produces carbon dioxide along with ATP – the energy currency of the cells. Anaerobic respiration occurs only in the cytoplasm of a cell. Aerobic respiration takes place in the presence of oxygen. What does your number mean? hydrogen ions pumped from the matrix into the intermembrane space. Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O 2).Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain. Anaerobic respiration is the type of respiration through which cells can break down sugars to generate energy in the absence of oxygen. The pyruvate that was created during glycolysis is converted to a two-carbon acetyl group, which … glycolysis occurs in the mitochondria glycolysis is the first step in both aerobic and anaerobic respiration glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate. 1. except coenzyme Q are proteins with prosthetic groups capable of being reversibly oxidized and reduced, most are hydrophobic, most of these intermediates occur in the membrane. When a cell needs to release energy, the cytoplasm (a substance between a cell's nucleus and its membrane) and mitochondria (organelles in cytoplasm that help with metabolic processes) initiate chemical exchanges that launch the breakdown of glucose. Look at figure 1 on page 59:  Where are the proteins that make up the electron transport chain located? End products: The end products of aerobic respiration are carbon dioxide, water, and energy. These are cells that contain a nucleus (brain of the cell) and organelles (little organs that each have their own job inside the cell).
