Question

21) Which process in eukaryotic cells will normally proceed whether O2 is present or absent? A) oxidative phosphorylation B) glycolysis C) Krebs cycle D) electron transport 22) The direct energy source that drives ATP synthesis during respiratory oxidative phosphorylation is A) thermodynamically favorable transfer of phosphate from glycolysis and Krebs cycle intermediate molecules of ADP. B) the thermodynamically favorable flow of electrons from NADH to the mitochondrial electron transport carriers. C) the final transfer of electrons to oxygen. D) the difference in H+ concentrations on opposite sides of the inner mitochondrial membrane. E) oxidation of glucose to CO2 and water. 23) DNP is a molecule that causes membranes to become more permeable to H+. What would you expect to happen to ar animal that is given an injection of this substance and kept on the same diet throughout the experiment? A) Its metabolic rate would decrease. B) It would produce excess amounts of ATP. C) It would become hyperactive. D) It would lose weight. E) It would have a lower body temperature. 24) The primary function of the mitochondrion is the production of ATP. To carry out this function, the mitochondrion must have all of the following EXCEPT A) proton pumps embedded in the inner membrane. C) enzymes for the Krebs cycle. E) the membrane-bound electron transport chain. B) enzymes for glycolysis. D) mitochondrial ATP synthase. 25) A major function of the mitochondrial inner membrane is the conversion of energy from electrons to the stored energ of the phosphate bond in ATP. To accomplish this function, this membrane must have all of the following features EXCEPT A) integral, transverse ATP synthase. B) the electron transport chain of proteins. C) proteins to accept electrons from NADH. D) high permeability to protons. E) proton pumps embedded in the membrane.

Answer 1

QUESTION 21

In this context, remember that glycolysis is a metabolic reaction where glucose is converted into pyruvate, hydrogen ions, and energy released in form of ATP. This reaction is oxygen independent and for this reason, it has been considered an ancient pathway. So, the correct answer is glycolysis
