Answer: B (GTP serves as the energy input for AMP synthesis from IMP)
Explanation:
In the de novo synthesis of purine nucleotide, IMP represents a branch point for purine biosynthesis. IMP can be converted to either AMP or GMP.
The formation of AMP from IMP requires GTP; similarly formation of GMP requires ATP. The conversion of IMP to either AMP or GMP is highly regulated – AMP and GMP inhibits their own formation by feedback inhibition of adenlyosuccinate synthetase and IMP dehydrogenase.
Answer:
Because of using fossil fuels nowadays it is used to air pollute the earth causing global warming.
Explanation:
A Ribosome is composed of ribosomal RNA and proteins.
They are made in the cell nucleus, in two types of subunits, the large and the small.
The subunits go to the cell body, where they can float free in the cytoplasm or attach to the rough endoplasmic reticulum.
