Bioenergetics and Anabolic Reactions Quiz

Biochemical operations can oxidize the carbon in substrates more completely to CO2.

Biochemical operations release more energy than chemical and physical operations.

Biochemical operations can convert soluble pollutants into an innocuous particulate form that can be easily removed. (correct)

Biochemical operations can treat sludges more effectively than chemical and physical operations.

Oxidizing the carbon in substrates completely to CO2.

Removing low concentrations of reacting constituents more efficiently than chemical and physical operations.

Treating sludges generated during the treatment process. (correct)

Producing energy-rich compounds like ethanol through fermentation.

The ability of the biochemical operations to convert the sludge materials into an innocuous particulate form.

The biochemical environment required for the treatment of the specific sludge materials. (correct)

The concentration of reacting constituents in the sludge determines the efficiency of the biochemical operations.

The oxidation state of the carbon in the sludge materials affects the energy release during the biochemical reactions.

<p>The oxidation of ethanol releases more energy than the oxidation of acetic acid because the carbon in ethanol is at a lower oxidation state.</p> Signup and view all the answers
