Oxygen is important for cell respiration as at the end of the electron transport chain, the electrons are donated to oxygen this occurs in the matrix at the surface of the inner membrane at the same time oxygen binds with hydrogen ions and forms water. A respirometer is the system used to measure cellular respiration pressure changes in the respirometer are directly relative to a change in the amount of gas in the respirometer, as long as the volume and the temperature of the respirometer do not change. Previous ib exam essay questions: unit 5 use these model essay question responses to prepare for essay questions on your in class tests, as well as the ib examination, paper 2 these questions have appeared on recent ib examinations, exactly as shown below.
Explain aerobic respiration including oxidative decarboxylation of pyruvate, the krebs cycle, nadh + h+, the electron transport chain, and the role of oxygen aerobic respiration strictly refers to the steps of cellular respiration known as the krebs cycle, electron transport chain, and oxidative phosphorylation. Cellular respiration can best be described as a using energy released from breaking high-energy covalent bonds in organic molecules to make atp b taking electrons from food and giving them to phosphate to make atp ib bio c: cell respiration topic 28 & 82 overview. Yeast is the quickest and most highly observable experiment type for the demonstration of cellular respiration the experiment will require a bag of active yeast (available in the baking goods section of any grocery store), some granulated sugar, a zip top bag, and a cup of mildly warm water.
Cell respiration is the controlled release of energy from organic compounds in cells to form atp the equation for aerobic cellular respiration is shown below 28u2 atp from cell respiration is immediately available as a source of energy in the cell. Cell respiration is the controlled release of energy from organic compounds in cells to form atp (adenosine triphosphates) 372 state that, in cell respiration , glucose in the cytoplasm is broken down by glycolysis into pyruvate, with a small yield of atp. Cellular respiration is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria in each cell cellular respiration involves a number of enzyme mediated reactions.
Understandings: cell respiration is the controlled release of energy from organic compounds to produce atp atp from cell respiration is immediately available as a source of energy in the cell.
