The oxidation of sugar molecules by the cell takes place according to the general reaction C6H12O6 (glucose) + 6O2 → 6CO2 + 6H2O + energy. Which of the following statements are correct? Explain your answers. a) All of the energy produced is in the form of heat. b) None of the produced energy is in the form of heat. c) The energy is produced by a process that involves the oxidation of carbon atoms. d) The reaction supplies the cell with essential water. e) In cells, the reaction takes place in more than one step. f) Many steps in the oxidation of sugar molecules involve reaction with oxygen gas. g) Some organisms carry out the reverse reaction. h) Some cells that grow in the absence of O2 produce CO2.

Step 1
All of the energy produced is in the form of heat. This statement is incorrect. While some of the energy produced is in the form of heat, a significant portion of the energy is stored in the form of ATP (adenosine triphosphate), which is used by the cell for Show more…

In the presence of oxygen, cells oxidize glucose completely to carbon dioxide and water according to the chemical equation: C6H12O6 + 6O2 → 6CO2 + 6H2O. In the process, about 35 molecules of ATP are generated per molecule of glucose oxidized, so that some of the energy released by oxidation is recovered as usable chemical energy. The principal role of O2 in this process is to: a - React with glucose to cleave it into smaller fragments for further oxidation b - Participate as a reactant in the generation of ATP from ADP and Pi c - Supply the oxygen for CO2 production d - Accept electrons released by glucose oxidation, forming H2O

The overall catabolic process of aerobic respiration uses glucose and oxygen (O2) as substrates. Which of the following statements CORRECTLY portrays aerobic respiration as a reduction-oxidation reaction? Both the carbon atoms in glucose and molecular O2 are reduced to CO2 and water, respectively. The carbon atoms in glucose are oxidized to CO2 and molecular O2 is reduced to H2O. Both the carbon atoms in glucose and molecular O2 are oxidized to CO2 and H2O, respectively. The carbon atoms in glucose are reduced to CO2 and molecular O2 is oxidized to H2O.

Cellular respiration is the process involved in the breakdown of glucose molecules in order to generate energy for cellular activities given the general reaction below which of the following best describes the products labeled X and Y C6H12O6 + O2 → _x___ + __y___ + energy A. The products are CO (carbon monoxide) and H2O2 (hydrogen peroxide), which then decompose into carbon dioxide (CO2) and wate (H2O) B. The products are H2O (water) and CO2 (carbon dioxide), which then undergo anaerobic respiration C. The products are CO2 (carbon dioxide) and H2O (water) which then become the reactants for photosynthesis D. The products are O2 (oxygen) and H2O (water), which are then used for growth and to keep the organism hydrated
