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.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
