Which of the following statements is false?
a.
b. Anabolic pathways are exergonic and release energy.
c. Catabolic pathways break larger substances into smaller substances.
d. The body “pays for” anabolic reactions with the energy from catabolic reactions.
Introduction:
All the living organisms require energy to carry out normal functions of the body. The energy obtained from different food sources are used by the body to create useful or essential products which help in growth and reproduction. Metabolism is the sum total of all reactions which takes place in the body and it includes both anabolism and catabolism.
Answer to Problem 1CYR
Correct answer:
Anabolic pathways are exergonic and release energy
Explanation of Solution
Justification/ Explanation for the correct answer:
Option ( b ) states that anabolic pathways release energy as they are exergonic. The statement is false because anabolism is building up a process where small molecules are combined to form a large or complex molecule. Anabolic pathways are endergonic as this reaction needs the energy to create bonds between small molecules. So, option ( b ) is correct.
Explanation for the incorrect answers:
Option (a) states that metabolism includes or refers to all the reactions which take place in the body. The statement is true as metabolism includes both anabolism, or building up process and catabolism, or breaking down process. So, it is an incorrect option.
Option (c) states that catabolic pathways include reactions which break down large complex substances into simpler ones. The statement is true because catabolism is a breaking down process which releases energy. So, it is an incorrect option.
Option (d) states that anabolic reactions get energy from catabolic reactions. The statement is true as the anabolic reactions require energy to create bonds and it is obtained from catabolic reactions which release energy by breaking chemical bonds. So, it is an incorrect option.
Hence, options (a), (c), and (d) are incorrect.
Thus, anabolic pathways are endergonic as it requires energy whereas catabolic pathways are exergonic as it releases energy.

- Nonearrow_forwardQuestion #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…arrow_forwardQuestion #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:arrow_forward

What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involvedarrow_forwardIf you wanted to reduce the difference between peak and trough levels that occur with repeated administration of a drug, how would you adjust the dose and dose interval without changing the plateau concentration (plateau is the average of peak and trough levels)? Select your answers for both dose and interval. Hint: It may be helpful to think about this problem using an example such as food. How would you eat if you wanted to maintain very steady hunger/satiety levels without changing your total caloric intake? Options: A. Dose; Increase dose B. Dose; Decrease dose C. Dose; Do not change dose D. Interval; Increase the interval between doses (give the drug less frequently) E. Interval; Decrease the interval between doses (give the drug more frequently) F.
