Summary Introduction

Introduction:

All animal bodies synthesize elements and molecules for proper functioning of their body organs within the body itself. However, there are still many elements and molecules that cannot be synthesized within the body and need to be supplemented from external sources.

Expert Solution & Answer

Answer to Problem 1TYK

Correct answer:

Essential nutrients.

Explanation of Solution

Justification/explanation for the correct answer:

Option (b) is given that required molecules that animals cannot synthesize are called essential molecules. This is a correct statement as there are many nutrients that are important for body functioning but cannot be synthesized within the body. Such nutrients are called essential nutrients/minerals or molecules. Vitamins, essential fatty acids, and organic and inorganic minerals are examples of essential molecules. Hence, option (b) is correct.

Explanation for the incorrect answers:

Option (a) says that required molecules that animals cannot synthesize are called nutrients. This is an incorrect statement as a correct definition of nutrition is “organic and inorganic compounds that a living organism derives from its environment to support essential life processes are called nutrients.” Humans acquire nutrients by ingestion of foods. Most essential nutrients can be synthesized by the body. So, it is an incorrect option.

Option (c) says that required molecules that animals cannot synthesize are called enzymes. This is an incorrect statement as enzymes are biochemical substance produced by a living organism and which act as a catalyst for a specific biochemical reaction. Almost all enzymes are proteins and they can be synthesized within the body in the ribosomes present in the cell cytoplasm. So, it is an incorrect option.

Option (d) says that required molecules that animals cannot synthesize are called proteins. This is an incorrect statement as proteins can be synthesized in our bodies in the ribosomes found outside the cell nucleus. Proteins are composed of many smaller units referred to as amino acids. In total, there are about twenty different amino acids types, which can be combined to make a protein. However, since our bodies can synthesize only 10 out of 20 amino acids, therefore, the rest are to be obtained from external sources. So, it is an incorrect option.

Option (e) says that required molecules that animals cannot synthesize are called carbohydrates. This is an incorrect statement as carbohydrates can be prepared in our bodies, starting in the endoplasmic reticulum and structurally grown in the Golgi complex. So, it is an incorrect option.

Hence, options, (a), (c), (d), and (e) are incorrect.

Conclusion

Thus, it can be concluded that molecules that are important for the body functioning but cannot be synthesized within the body of the animals are called essential molecules.

Students have asked these similar questions

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW). If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?

None

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…
