From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of acetyl CoA formation. The figure does not show most of the inputs and outputs of cellular respiration. 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. Drag each compound to the appropriate bin. NAD+, ATP, ADP, CoEnzyme A, CO2, Acetyl CoA, Pyruvate, NADH, O2, Glucose Sort 6. Is the formula balanced as written? Predict: Of the molecules shown on the MOLECULES pane, which do you think are inputs (ingredients) in cellular respiration2. Describe how different energy sources are used in cellular respiration 8. 1. 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. Glucose is anaerobically oxidized to pyruvic acid in cytoplasm, through glycolysis (Greek: glykys = sweet and lysis = breakdown). Made during the citric acid cycle and released to the atmosphere. How to solve: What are the inputs, outputs, and any enzymes of glycolysis, citric acid cycle, and electron transport chain? Although both of these processes involve a series of complex steps, the inputs and outputs of each process are four relatively simple molecules. In acetyl CoA formation, the carbon-containing compound from glycolysis is oxidized to produce acetyl CoA. You will use your understanding of this figure to answer the next 7 questions.

Overall Inputs and Outputs of Cell Respiration Used to start glycolysis Needed from the atmosphere to accept electrons at the ETC. How to solve: What are the inputs and outputs of the Krebs Cycle, and what function do the outputs have? Describe the roles of ADP, ATP, NAD+, NADH, and a proton gradient in the enzyme reactions of the Question: What are the inputs and outputs of cellular respiration? 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. Location, inputs and outputs of each step. Welcome to the Memrise course for BIO 205: Microbiology. Glycolysis takes place in the cytoplasm, the jelly-like substance that fills the inside of cells. 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). 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. So 34 net input - net output - neither - _____ Glucose is a simple sugar. What What is the chemical formula of oxygen? net input - net output - neither - HELP! We used the figure below to diagram the inputs and outputs for each of the processes involved in cell respiration. If the compound is not involved in glycolysis, drag it to the not input or output bin. 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 (The electron transport chain needs O 2 as an input and produces H 2 O. Glycolysis, the preparatory stage and the Krebs or citric acid cycle. Is it an anabolic or catabolic process? Based on your observations, write a simplified formula for photosynthesis: CO2 + H2O → C6H12O6 + O2 Turn on Show input/output formula to check.
