- Which of the following statements is true regarding a reducing agent?
- During the citric acid cycle, the production of CO2 is a(n) _____ reaction coupled to the production of ____________.
- The breakdown of fatty acids takes place via a process called:
- Which one of the following complexes does not actively move protons from the mitochondrial matrix to the intermembrane space?
- In human cells such as muscle tissue, the product of anaerobic respiration is
- Which regulatory mechanism is activated when the overall energy availability of a cell is high
- The breakdown of one glucose molecule during glycolysis results in 2 molecules of pyruvate, which are then oxidized to 2 molecules of acetyl-CoA, and these, in turn, are substrates for the citric acid cycle. If all three fatty acids of a triacylglycerol molecule (a fat molecule) are palmitic acid (C16, having 16 carbons), how many acetyl-CoA molecules would result from beta-oxidation of all of these fatty acids?
- Consulting Figure 7.1 if necessary, during which stage(s) of cellular respiration is(are) carbon dioxide released?
- In which of the following molecules are the electrons of the atoms shared in covalent bonds at the furthest distance from the nucleus?
- Which of the following is a mobile electron carrier in the electron-transport chain?
- Due to the pumping action of the electron transport chain, protons have a high concentration in the _____ and a low concentration in the _____.
- How many reactions in glycolysis directly generate ATP
- True or False: fats are not an animal's primary source of energy because some tissue types like brain tissue use glucose exclusively.
- In which form are electrons transferred during typical redox reactions such as the oxidation of glucose?
- The citric acid cycle begins when acetyl-CoA combines with ____________ to form ____________.
- In cellular respiration, glucose is _____ to CO2 and oxygen is _____ to water.
- The approximate yield of ATP from the full oxidation of a molecule of glucose is:
- Which regulatory mechanism is important in keeping glycolysis and the citric acid cycle in relative balance to each other
- The ATP produced during glycolysis is the result of substrate-level phosphorylation
- Glycogen stored in muscles can be "mobilized" to supply metabolic energy by hydrolyzing individual glucose subunits from the polymer. What other organ has a major function of storing glycogen?
