You may need to state 'Yes' or 'No' in more than one box in a particular row in some cases. Cellular Respiration Feature Involved in aerobic respiration Occurs in the mitochondrial matrix Pyruvate molecules are produced Acetyl COA combines with a 4 carbon molecule Electrons are passed between protein carriers ATP is produced NAD+ gains hydrogen FADH₂ loses hydrogen Glycolysis Yes / No Krebs Cycle Yes / No Electron Transport chain Yes / NoFor the theoretical maximum yield of ATP per glucose molecule oxidized by aerobic respiration, we will assume that for each pair of electrons transferred to the electron transport chain by NADH, 3 ATP will be generated; for each electron pair transferred by FADH2, 2 ATP will be generated. If NADH is produced in the cytoplasm, it will only generate 2 ATP but NADH produced in the mitochondria will release 3 ATP.

Location: Show where this stage of cellular respiration occurs within the cell (e.g., cytoplasm, mitochondria). Energy Production: Highlight the ATP and NADH production at this stage. Oxygen: Show where oxygen is used in the process (e.g., ETC) and where carbon dioxide is produced. Electron Carriers: Indicate the role of electron carriers such as NAD+ and FAD in transferring eleDiagrams: Use diagrams or icons to represent the structures and molecules involved, such as the mitochondria, glucose, ATP, and oxygen. Key Information like important facts or formulas relevant to cellular respiration, like the chemical equations for each stage.b) Place a 'Yes' or a 'No' in the appropriate boxes that correspond to each listed feature of cellular respiration.
