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?
