Question

Two intermediates of the sterol biosynthesis pathway, isopentenyl diphosphate and dimethylallyl diphosphate, are used by archaea in the biosynthesis of _____?

1) isoprenoids
2) nucleotides
3) diacylglycerol
4) hormones

Answer 1

Two intermediates of the sterol biosynthesis pathway, isopentenyl diphosphate and dimethylallyl diphosphate, are used by archaea in the biosynthesis of 1) isoprenoids.

Step-by-step explanation:

Isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) are two intermediates in the sterol biosynthesis pathway that are used by archaea to produce isoprenoids. Isoprenoids, also known as terpenoids, are a diverse group of lipids that play important roles in plants and animals. They include compounds such as carotenoids, hormones, and steroids.

Isoprenoids are formed by condensing IPP and DMAPP to produce geranyl pyrophosphate (GPP), which is then converted into various isoprenoid compounds through chemical modifications. Isoprenoids have a wide range of functions, including acting as pigments, fragrances, and signaling molecules.

In conclusion, archaea use isopentenyl diphosphate and dimethylallyl diphosphate in the biosynthesis of isoprenoids. Isoprenoids are a diverse group of lipids that have important biological functions. They are formed by condensing isopentenyl diphosphate and dimethylallyl diphosphate to produce geranyl pyrophosphate, which is then converted into various isoprenoid compounds. The correct answer is 1) isoprenoids.
