This diagram showcases the enzymes and steps of photosystem I and photosystem II and explores how these systems create a concentration gradient which powers the production of ATP through the ATP synthase compound. Identify the parts of the mitochondrion: The Krebs Cycle occurs only when oxygen is present, but does not use it directly. List the inputs (raw materials) and outputs (products) of glycolysis, the Krebs Cycle, and the respiratory (electron transport) chain. Steps of Oxidative Phosphorylation: The steps used for the process of Oxidative Phosphorylation are: Delivery of electrons by NADH and FADH2: From other steps of cellular respiration, reduced electrons carriers (NADH and FADH2) transfer their electrons to molecules near the beginning of the electron transport chain. Describe the relationships of glycolysis, the citric acid cycle, and oxidative phosphorylation in terms of their inputs and outputs. Inputs and Outputs? Oxidative phosphorylation works by using energy-releasing chemical reactions to drive energy-requiring reactions: The two sets of reactions are said to be coupled.This means one cannot occur without the other. Point out where in the aerobic respiratory pathway O 2 is used and CO 2 is produced. This process is called chemiosmosis. Parent: Cellular respiration is complex! It also compares aerobic and anaerobic respiration (fermentation). Describe how ATP is made by chemiosmosis in an electron transport chain (oxidative phosphorylation). to divider? The Citric Acid Cycle. 2 NAD+ (4 ADP) 2 pyruvate. We illustrate the general approach to input/output reduction using a simple example involving 10 DMUs of an organization with two inputs and two outputs.The data are summarized in Table 1.Suppose that the organization has to reduce the first input and second output and the amount of these reductions are respectively C 1 = 75 and F 2 = 150. Fill in the following table to summarize the major inputs and outputs of glycolysis, the citric acid cycle, oxidative phosphorylation, and fermentation. Water splitting photosystem- energy captured from a photon of light and as excited electron in the chlorophyll molecules fall back to the resting state, energy is released and funneled to a nearby molecule. Cellular respiration. to cover? Photosynthesis. Communications among the nucleus, mitochondria, and chloroplasts are essential in stress tolerance. 27. If oxygen is available, aerobic respiration will go forward. The rotary motion of ATP synthase in turn drives the synthesis of ATP from ADP and phosphate. PM ME IF INTERESTED. Cellular Respiration. Includes Notes ( E.T.C. The movement of ions across the selectively permeable mitochondrial membrane and down their electrochemical gradient is … In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into mitochondria, which are sites of cellular respiration. It is an extremely complex process, comprised of many coordinated biochemical reactions. From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of acetyl CoA formation. *In acetyl CoA formation, pyruvate (a product of glycolysis) is oxidized to acetyl CoA, with the reduction of NAD+ to NADH and the release of one molecule of CO2. As hydrogen ions diffuse down concentration, they charge gradients through ATP synthase. Base inputs and outputs on one glucose molecule. ADP, acetyl CoA, pyruvate, NAD+, ATP, CO2, NADH, coenzyme A, O2, glucose how can I categorize them? 2 ADP 4 … Glycolysis? 2 NADH.
