Students receive a handout (see pdf below) and are asked to label inputs and outputs of a 4-box diagram, with the boxes intended to represent glycolysis, pyruvate oxidation, citric acid (Krebs) cycle, and the electron transport Outputs: 4 CO2, 6 NADH, 6 H+, 2 FADH2, 2 ATP, and 2 CoA One ATP is produced per turn of the cycle (two cycles in total), so 2 ATP are produced for this step of cellular respiration. How are the high energy electrons captured from glycolysis and the citric acid cycle converted into ATP in 6a. Glycolysis From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of glycolysis. It includes glycolysis, the … Challenge: To balance the inputs and outputs of cellular respiration, there should be the same number of carbon, oxygen, and hydrogen atoms on each side of the arrow. Welcome to the Memrise course for BIO 205: Microbiology. Glucose is anaerobically oxidized to pyruvic acid in cytoplasm, through glycolysis (Greek: glykys = sweet and lysis = breakdown). What NAD+, ATP, ADP, CoEnzyme A, CO2, Acetyl CoA, Pyruvate, NADH, O2, Glucose Sort 6. Drag each compound to the appropriate bin. In acetyl CoA formation, the carbon-containing compound from glycolysis is oxidized to produce acetyl CoA. Cellular respiration (1 of From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of acetyl CoA formation. (Inputs and outputs increased by a factor of two to represent the Krebs cycle's total output for each glucose molecule that undergoes glycolysis.) Glycolysis requires the input of 2 ATP molecules for each molecule of glucose. Glycolysis is divided into two categories: aerobic (chemical reactions that occur with the presence of oxygen) and anaerobic (chemical reactions that do not require oxygen). If the compound is not involved in glycolysis, drag it to the not input or output bin. net input - net output - neither - Location, inputs and outputs of each step. o At the end of glycolysis, the cell has built two molecules of pyruvic acid. The figure does not show most of the inputs and outputs of cellular respiration. It occurs in the cytoplasm, does not require oxygen and results in the net production of two ATP. Ignore words Check the boxes below to ignore/unignore words, then Correct answers: 1 question: From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of glycolysis. (The electron transport chain needs O 2 as an input and produces H 2 O. However, 4 … Glycolysis, the preparatory stage and the Krebs or citric acid cycle. ADP, acetyl CoA, pyruvate, NAD+, ATP, CO2, NADH, coenzyme A, O2, glucose how can I categorize them? Describe the inputs and outputs of this process. Metabolism (Inputs and Outputs). In contrast, the organisms which synthesize atp, in case oxygen is present, and switch to fermentation in the absence of oxygen are called facultative anaerobes. We used the figure below to diagram the inputs and outputs for each of the processes involved in cell respiration. Glycolysis was discovered by Embden, Meyerhof and Parnas, therefore, glycolysis is also known as Made during the citric acid cycle and released to the atmosphere. 3 Cellular Respiration A cellular process that breaks down carbohydrates and other metabolites with the concomitant buildup of ATP Consumes oxygen and produces carbon dioxide (CO 2) Cellular respiration is aerobic process. Based on your observations, write a simplified formula for photosynthesis: CO2 + H2O → C6H12O6 + O2 Turn on Show input/output formula to check. The Citric Acid Cycle In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into mitochondria, which are sites of cellular respiration. Describe the relationships of glycolysis, the citric acid cycle, and oxidative phosphorylation in terms of their inputs and outputs. And then eventually, these outputs from glycolysis and the citric acid cycle, when they get into the electron transport chain, are going to produce another 34. If you're not in my class feel free to jump in and start learning anyway. Glycolysis: The Initial Steps: Energy Input ª In the process of glycolysis, glucose, a six-carbon molecule, is split into two pyruvates (three-carbon molecules). Describe the major inputs and outputs of glycolysis, the citric acid cycle, and the electron transport system. The LibreTexts libraries are Powered by MindTouch ® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. ª The first stage of glycolysis involves an energy investment of two ATP. These two molecules can now enter one of three different stages of energy production. You will use your understanding of this figure to answer the next 7 questions. Is it an anabolic or catabolic process? Describe how different energy sources are used in cellular respiration 8. From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of glycolysis. Overall Inputs and Outputs of Cell Respiration Used to start glycolysis Needed from the atmosphere to accept electrons at the ETC. Glycolysis takes place in the cytoplasm, the jelly-like substance that fills the inside of cells. _____ Glucose is a simple sugar. Identify and describe the inputs and outputs of cellular respiration, glycolysis, pyruvate processing, citric acid cycle, and electron transport chain 7. If the compound is not involved in glycolysis, drag it to the "not input or output" bin.gluclose, ADP, ATP, O2, How to solve: What are the inputs and outputs of the Krebs Cycle, and what function do the outputs have? Select the RESPIRATION tab. Summarize: Although photosynthesis is a complex process involving many reactions, it can be summarized by a simplified formula that shows inputs on the left and outputs on the right. Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Net Inputs- Glucose, ADP, NAD+ Net Outputs- Pyruvate, ATP, NAD Neither- CO2, Acetyl CoA, O2, coenzyme A From the following compounds involved in cellular respiration (pyruvate, CO2, ADP, Glucose, NAD+, Acetyl CoA, NADH,ATP, O2, coenzyme A) , choose those that are the net inputs and net outputs of the citric acid cycle. Glycolysis is the name for the series of reactions that takes place in all cells, prokaryotic and eukaryotic, to break down the six-carbon sugar glucose into two three-carbon pyruvate molecules. Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. Add the missing inputs and outputs to the figure. 6d. Describe the roles of ADP, ATP, NAD+, NADH, and a proton gradient in the enzyme reactions of the For every 1 molecule of glucose, glycolysis produces 2 molecules of pyruvate, 2 molecules of NADH, and 2 molecules of ATP.
