The catalytic activity of enzymes is important to ensure and regulate cellular metabolism . Introduction: Enzyme is a biological molecule. In the human body, enzymes assist to accelerate or speed up the chemical reactions. A substrate binds to the enzymes’ active site and is converted to products. In the cell, all metabolic processes need enzyme catalysis in direction to occur at the fast rates that are sufficient to endure life.

Expert Solution & Answer

Explanation of Solution

Enzymes regulate all the biochemical reactions that happen in living cells. Most of these reactions do not occur at a significant rate in the absence of activation of enzymes. Thus, enzymes catalyze all the characteristics of cellular metabolism. It includes digestion of large molecules of nutrient. For example, carbohydrate, proteins, lipids break down into smaller molecules, transformation, and production of energy that leads to the formation of large molecules, which is significant for the cell variability. Thus, the catalytic activity of the enzyme is essential in regulating the metabolism of the cells.

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:
