Respiration process that occurs in the presence of oxygen is called aerobic respiration, generally seen among humans. But in certain organisms like bacteria and algae, respiration occurs in the absence of oxygen, called anaerobic respiration. In both the types of respiration, it is the glucose (carbohydrate molecule) that undergoes reactions.
Why is O2 so important for respiration? Oxygen is a critical component of Aerobic respiration in many animals. The reason why oxygen is so important is because it plays a crucial role in the mitochondria, the powerhouses of the cell. The mitochondria has two membranes. On the inner membrane, 4 groups of protein form the Electron Transport Chain.
There are four stages of aerobic respiration- glycolysis, which takes place in the cell cytoplasm and the link reaction, Krebs cycle, and oxidative phosphorylation, which all occur in the mitochondria.Glycolysis splits glucose into 2 pyruvate molecules, producing 2 ATP molecules and 2 reduced NADH. The link reaction takes pyruvate and produces ...
In the last stage of respiration, some protons leak through the inner mitochondrial membrane back inside the matrix, so proton motive force which spins the headpiece of ATP synthase to produce ATP is decreased, hence less ATP produced.
Describe with a summary picture the aerobic respiration from glucose (CHO) all the way to Co2 and water. Highlight, with yellow the flow of H (and then electrons and protons) and in red the ATP Include: inner membrane, outer membrane, matrix, intermembrane space glycolisis, Krebs cycle (citirc acid), e.t.c. (oxidative phosphorilation) ATP synthase, NADH dehydrogenase complex, cyt b-c1complex ...
Aerobic respiration involves the exchange of respiratory gases at two places in muticellular animals-one between the body surface and surrounding medium, the other between the individual cells and the extracellular fluid. Lungs are involved in the first step ofheart.
Anaerobic respiration. 1. It occurs in the presence of oxygen. It occurs in the absence of oxygen. 2. Food materials are completely oxidised to release carbon dioxide, water and energy. Food materials are incompletely oxidised to release alcohol, carbon dioxide and energy. 3. Sufficient amount of energy is released.
Aerobic respiration Fermentation 1 Oxygen is used for deriving energy. It o ccurs in the absence of oxygen. 2 It o ccurs in the cytoplasm and mitochondria. It o ccurs in the cytoplasm. 3 End products are carbon dioxide and water. End products are ethyl alcohol 4
Breathing. Respiration. Meaning. It refers to the process of inhaling oxygen and exhaling carbon dioxide through the lungs. It is a process where breaking down of glucose produces energy and the cell uses it to perform cellular work. Occurrence. It occurs in the lungs. It takes place in cells. Cellular activity.
Oxygen is critical for aerobic respiration. Explain its role with respect to ETS. In the Electron Transport System, N A D H + H + and F A D H 2 are energy carriers and are utilized to produce ATP. Electrons are transferred through a sequence of events and finally to the oxygen molecule. The oxygen molecule works like the final acceptor of ...
