Summary Introduction

Introduction:

In the body, there are trillions of cells and each cell is performing a function. The energy used to power these functions comes from the food that the organisms eat, but is not used in the same form. Rather, the energy in the food is converted into forms that the cell can utilize like adenosine triphosphate (ATP).

Answer to Problem 1MC

Correct answer:

The equation of glycolysis under aerobic conditions is the reverse of the photosynthesis.

Explanation of Solution

Explanation for the correct answer:

Option (d) is given that photosynthetic equation and the equation of glycolysis in the presence of oxygen are reversed with respect to each other. This is a true statement as in aerobic respiration; glucose is broken down into carbon dioxide (CO2) and water (H2O) in the presence of oxygen releasing energy. On the contrary, during photosynthesis, H2O and CO2 are utilized as reactants in the presence of sun’s energy to be converted into glucose and oxygen. Hence, option (d) is correct.

Justification for the incorrect answers:

Option (a) is given that two ATPs are produced by the process of fermentation. This is a false statement as fermentation does not produce ATP. Only nicotinamide adenine dinucleotide (NAD+) ions are regenerated. So, it is an incorrect option.

Option (b) is given that the net ATP production of glycolysis and fermentation combined is four. This is wrong as the glycolysis only produces two ATP molecules and fermentation produces none. So, it is an incorrect option.

Option (c) is given that at the end of glycolysis, ethanol is produced. This is a wrong statement as the production of ethanol occurs in the process of fermentation and not in glycolysis. So, it is an incorrect option.

Hence, options, (a), (b), and (c) are incorrect.

Conclusion

Thus, it can be concluded that the equation of glucose breakdown in the presence of oxygen is the reverse of the photosynthetic equation.
