6 Questions
Which of the following is the primary reason that biochemical operations function more efficiently than chemical and physical ones when the concentrations of reacting constituents are low?
Biochemical operations can convert soluble pollutants into an innocuous particulate form that can be easily removed.
According to the passage, which of the following is the primary use of biochemical operations in wastewater treatment?
Treating sludges generated during the treatment process.
The passage states that the efficacy of a biochemical operation in treating sludge depends strongly on the nature of the materials in the sludge. Which of the following is the most likely reason for this?
The biochemical environment required for the treatment of the specific sludge materials.
According to the passage, which of the following is true about the oxidation of acetic acid to CO2 and the oxidation of ethanol to CO2?
The oxidation of ethanol releases more energy than the oxidation of acetic acid because the carbon in ethanol is at a lower oxidation state.
Why can CO2 never act as an energy source according to the passage?
Because the carbon in CO2 is at the highest possible state of oxidation and cannot be further oxidized.
Which of the following is the primary difference between aerobic respiration and fermentation according to the passage?
Aerobic respiration can oxidize the carbon in the substrate completely, while fermentation cannot.
