Interpretation:
The given events in catabolic process namely electron transport, digestion, oxidative phosphorylation and citric acid cycle should be arranged in correct order.
Concept Introduction:
Electron transport chain: The series of pathway where the electron gets passed from reduced coenzymes to the oxygen which gets finally coupled resulting in formation of
Oxidative phosphorylation: The production of
Citric Acid Cycle: It involves 8 series reaction which converts acetyl group present in acetyl coenzyme A into 2
Digestion: It is the process of larger consumed food particles into smaller that processed and results as lipids, carbohydrates and proteins.

- Indicate whether each of the following processes would be expected to involve the conversion of ATP to ADP or the conversion of ADP to ATP. a) Heart muscle contraction b) transport of nutrients to various locations in the bodyarrow_forwardThe coenzymes NAD+ and NADP+ are important electron carriers that pick up electrons from one pathway and deliver them to another. Below is a list of pathways or enzyme complexes that we have covered in class. Indicate which coenzyme these pathways or complexes produce by writing NAD+, NADP+, NADH or NADPH in the blank provided. ________ glycolysis ________ citric acid cycle ________ alcoholic fermentation ________ pyruvate dehydrogenase complex ________ gluconeogenesis ________ mitochondrial electron transport ________ photosynthesis light reactions ________ photosynthesis dark reactionsarrow_forwardName the three main catabolic pathways and the estimated ATP yield for each.arrow_forward
- a) Describe the three irreversible reactions of the Citric Acid Cycle. Ensure to indicate their purpose/role, the substrates and products, the enzyme involved, and any significant features of the reaction. b) Why are these reactions considered irreversible (why can't they be reversed)? c) Using one of the reactions as an example, explain why it is important for the cell that the reaction is irreversible.arrow_forwardWhich statement best describes the reason why some of the reactions of glycolysis cannot be run in reverse in gluconeogenesis? 1) The last reactions occur in mitochondria and reactions there can never be reversed. 2) Glycolysis includes isomerization reactions and these can never be reversed. 3) There are some allaşteric enzymes and allosteric enzymes can never be reversed. 4) Some reactions have such large negative free energy changes that they can never be reversed under cellular conditions. Oarrow_forwardComplete catabolism of one glucose molecule yields 38 ATP molecules. How many moles of ATP are produced by the complete catabolism of 10 moles of glucose?arrow_forward
- If glycolysis has an overall –DG (i.e., it’s exergonic), why does it require an energy investment of two ATP to happen?arrow_forwardThe reaction pictured is an oxidation-reduction reaction in the citric acid cycle in which the energy-carrier molecule NADH is generated. Identify which molecule in the reaction will be oxidized and which molecule will be reduced. Place a single answer choice in each box. COO- HO-C-H H-C-H COO- Malate NAD+ NADH + H+ Oxidized malate oxaloacetate COO- H-C-H ī COO- Oxaloacetate Reduced NADH NAD+arrow_forwardWhy does glycolysis require ATP investment on a thermodynamic and molecular level?arrow_forward
- In which of the following metabolic conversions is ATP “generated” during glycolysis? Phosphoenolpyruvate -> pyruvate 2-Phosphoglycerate —> Phosphoenolpyruvate Glucose-6-phosphate —> Fructose-6-phosphate Fructose-1,6-bisphosphate —> Dihydroxyacetone phosphate + Glyceraldehyde-3-phosphate Fructose-6-phosphate —> Fructose-1,6-bisphosphatearrow_forwardGive all the reversible reactions in glycolysis. Specify the enzymes involved that catalyze each reactionarrow_forwardPlace the following steps in the catabolism of carbohydrates in order: the electron transport chain, the conversion of glucose to acetyl CoA, the hydrolysis of starch, oxidative phosphorylation, and the citric acid cycle.arrow_forward
