Which of the following is False?

a. Carbohydrates are the major energy storage molecule of plants.

b. Carbohydrates are the major source of rapidly available energy stores in people.

c. Carbohydrates include cellulose.

d. Carbohydrates are hydrophobic and don't retain water in the body.

Expert Solution & Answer

Summary Introduction

Introduction:

Carbohydrates come in the simple forms like sugars and in complex forms such as starches and fibers. It can also be defined as neutral compounds of carbon, hydrogen, and oxygen.

Answer to Problem 1MC

Correct answer:

Carbohydrates are hydrophilic and they contain multiple hydroxyl groups which can form hydrogen bonds with water molecules. Therefore, option (d) is correct.

Option (d) is given as “Carbohydrates are hydrophobic and don’t retain water in the body”.

Explanation of Solution

Justify reasons for the correct statement:

All carbohydrates composed of carbon, hydrogen, and oxygen. These molecules come together in different arrangements to form single or double units called as sugars, and longer units called as starches or fibers. Carbohydrates are hydrophilic compounds.

Hence, option (d) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “carbohydrates are the major energy storage molecule of plants”.

Polysaccharides molecules are the most abundant carbohydrates; they can contain thousands of glucose units. As the above mentioned statement is true, hence, it is a wrong answer.

Option (b) is given as “carbohydrates are the major sources of rapidly available energy stores in people”.

Most of the organism use carbohydrates as energy source. It can be metabolized and provide energy. Monosaccharides like glucose and disaccharides like sucrose and fructose are absorbed from the intestine and are immediately metabolized to produce energy. As the above mentioned statement is true, hence, it is a wrong answer.

Option (c) is given as “carbohydrates include cellulose”.

Cellulose is the polymer of glucose and it is the most abundant polysaccharide on the Earth. It provides mechanical support to the plant structures. As the above mentioned statement is true, hence, it is a wrong answer

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

Conclusion

Carbohydrates are hydrophilic in nature and they retain water in the body.

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:
a. What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent.  b. What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involved
