Which of the following cellular processes or reactions could decrease the entropy of an organism?     Glycolysis     Hydrolysis of ATP     Calvin cycle     Citric acid cycle     Metabolism of starch to produce glucose

Strong evidence in support of the common ancestry of all life comes from which of the following observations about living things? O the fact that decomposers include both bacteria and fungi O the existence of a nearly universal genetic code O the ability of plants to convert light energy to chemical energy

Which of the following represents the "oxidative" portion of oxidative phosphorylation? glycolysis pyruvate oxidation the citric acid cycle the electron transport chain ATP synthase

Which of the following describes the critical role that ATP plays in cellular metabolism? ATP serves an energy shuttle in the cell, coupling exergonic anf exergonic reactions. The terminal phosphate group of ATP is attached by a particular strong covalent bond that releases extra energy when broken. It is one of the four building blocks for RNA synthesis. Hydrolysis of ATP provides energy to drive exergonic reactions in the cell.

Which of the following processes will result in a direct net increase of ATP concentration?   Group of answer choices Anabolic chemical pathways Primary Active transport dehydration synthesis Glycolysis

What is the largest source of ATP in the cell? The oxidation of sugar during glycolysis The oxidation of pyruvate The Krebs Cycle Oxidative phosphorylation

Which of the types of energy is NOT one a part of energy transformation chain during respiration and photosynthesis? mechanical energy- kinetic energy of moving objects nuclear energy - energy released during radioactive decay chemical energy - energy released when the products of a reaction have a lower free energy than the reactants potential energy stored in a gradient of concentration

ATP is an important molecule in cellular energetics. Which of the following statements is false? ATP hydrolysis can provide the energy required for mechanical work in a cell. All of the ATP made during cellular respiration is made by the enzyme ATP synthase. ATP synthesis is an endergonic reaction. None of the other answers are false.

If a compound that allows protons to freely diffuse across membranes is added to cells that are actively metabolizing glucose via cellular respiration, which of the following processes would stop? Glycolysis Electron transport ATP synthesis None of the above All of the above

Which of the following statements is NOT true?   None of the other four answers (all are true) The energy required to cause a chemical reaction to occur is called the activation energy Decomposition (degradation, catabolic) reactions are usually endergonic Chemical reactions in living cells are catalyzed by enzymes Enzymes increase the probability that a chemical reaction will take place by lowering the activation energy
