Interpretation:
The reason why
Concept Introduction:
Oxidation: The oxidation is reaction that involves addition of oxygen atom or loss of electrons or removal of hydrogen atom present in the chemical compound.
Exergonic: The reaction is considered as exergonic if energy released since the reactants loses its energy making the free energy more negative hence making it spontaneous reaction.
Endergonic: The reaction is considered as endergonic if it needs more energy means that activation energy is much higher making the reaction non spontaneous.

- You are studying a metabolic pathway and are trying to decide if it is an anabolic pathway or a catabolic pathway. Which of the following would help diagnose this problem? A) Look for common intermediates. B) Look for ATP-requiring steps. C) Look for enzymes under allosteric regulation. OD) All of the above. OE) None of the above.arrow_forwardThe figure above represents changes in different types of metabolic pathways (y-axis) as energy charge in a cell (x-axis) changes. What is the best description of the types of reactions shown by the green line labeled "A"? a) Catabolic, energy-consuming pathways b) Anabolic, energy-consuming pathways c) Anabolic, energy-producing pathways d) Catabolic, energy-producing pathwaysarrow_forwardIn a metabolic pathway, what is the rate-limiting reaction?arrow_forward
- Is it likely that any metabolic pathway can exist without control mechanisms?arrow_forwardThere are six major groups of enzymes. The categories are based on the types of reactions that they catalyze. What type of enzyme converts a molecule to another structure with the same formula through breaking bonds and forming new bonds. A) Lyases B) Transferases C) Hydrolases D) Isomerases E) Ligasesarrow_forwardWhat is the difference between a linear and a cyclic metabolic pathway?arrow_forward
- Which of the following are common to all metabolic pathways? a) Citric acid cycle b) Oxidative phosphorylation c) Electron transport chain d) All of the abovearrow_forwardAllosteric enzymes: A)usually catalyze several different reactions within a metabolic pathway. B)are regulated primarily by covalent modification. C)usually show strict Michaelis-Menten kinetics. D)usually have more than one polypeptide chain E)usually have only one active site.arrow_forwardcreate a single illustration that will interrelate or link the two opposing pathways, the Glycogenesis and Glycogenolysis. I want you to include the enzyme in each step and include some important by-products as well. From the illustration, I want you to encircle the intermediate molecule to highlight the link between the two processes. Aside from the illustration, I want you to compare and contrast the two pathways in terms of function, number of reaction steps, and usage of UTP. You can tabulate this part to make it simpler.arrow_forward
