Which statement(s) is(are) true of biosynthesis and the generation of building blocks?

Select all that apply.

- Building blocks are more reduced than precursor metabolites

- Approximately 75-100 precursor metabolites are required to synthesis the many building blocks required to assemble a complete bacterial cell

- Obligate parasites typically have more biosynthetic pathways than free-living species

- The genes detected in an organism’s genome can provide information about its biosynthetic capabilities

- A key function of biosynthesis is the synthesis of ATP

Expert Solution

The answer is 1st and 4th options. 1st and 4th statements are true

1st statement is true. Building blocks are complex molecules used in synthesis of macromolecules. Building blocks are synthesized from precursor metabolites. 75 - 100 building blocks are produced from 12 precursor metabolites. Building blocks are large complexes used to synthesize macromolecules. Building blocks are more reduced form than precursor metabolites

4th statement is true. The biosynthetic gene cluster is an organized group of genes that are involved in biosynthesis.

2nd statement is False. Precursor metabolites are used as substrates in biosynthesis. Building blocks required in biosynthetic pathways are derived from 12 precursor metabolites. 75 - 100building blocks can be synthesized from 12 precursor metabolites

3rd statement is False. Obligate parasites lack certain metabolic pathways that free-living species possess. Obligate parasites have very less biosynthetic pathways than free-living species

5the statement is False. In biosynthesis, the macromolecules are formed from simple compounds. In order to take place biosynthesis, chemical energy in the form of ATP is necessary. ATP is a prerequisite element in the process of biosynthesis
