De novo purine synthesis occurs by the stepwise addition of atoms or groups of atoms to 5‑phosphoribosyl 1‑pyrophosphate (PRPP).

The atoms of the purine rings are supplied by glutamate, glycine, glutamine, aspartate, and N 10 ‑formyltetrahydrofolate (THF). Inosine monophosphate (IMP), the product of the pathway, is a purine nucleotide that can be converted to either AMP or GMP. The structure of the base is labeled according to the numbering convention for purines. Identify the direct source of each atom in the purine ring of IMP.

Answer:

Explanation:

Like we all know, the purine ring of IMP is made up of a nine membered compound . they are heterocyclic aromatic organic compound that consist of a pyrimidine ring fused to an imidazole ring. there are four nitrogen atoms and five carbon atom.

The ring is imidazole ring is made up of N1, C2, N3, C4, C5, C6 with the pyrimidine sharing C4 and C5 with the imidazole ring and also made up of N7, C8, N9.

the direct source of N1 is from aspartate

the direct source of C2 and C8 is from N 10 ‑formyltetrahydrofolate (THF)

N3 and N9 is derived from the amide group of Glutamine

C4, C5 and N7 is derivd from Glycine

C6 is derived from bicarbonate

Explain the role of bacteria in the nitrogen cycle
Oksanka [162]

Bacteria is important because this bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil.  During assimilation, or when plants take up nitrates from the soil, bacteria aid in the process with the plants in making ammonia. Animal wastes is also a major place where bacteria thrives and produces ammonia. The process in which assimilation occurs in plants, and then bacteria converts the nitrates to ammonia is called ammonification.  From the conversion of ammonia to nitrites, bacteria also aids in this process called nitrification. The nitrifying bacteria mostly present in soils, oxidize ammonia into nitrites, and from nitrites to nitrates.

Finally, the process of denitrification also has bacteria present to aid in converting nitrates back into a gaseous form of nitrogen in the atmosphere.

In a plant cell, DNA can be found in?
hoa [83]

Answer:

D. All of the above

Explanation:

Like all living organisms, plants use deoxyribonucleic acid (DNA) as their genetic material. The DNA in plant cells is found in the nucleus, the mitochondria and the chloroplasts. The latter two organelles are descendants of bacteria that were captured by a eukaryotic cell and have become endosymbionts.

Two males weigh 195 pounds and are 45 years old. one has a body fat percentage of 13% and the other's body fat percentage is 29%
Komok [63]
The burn of calories is connected to gender, mass and the age. These characteristics are the similar for both individuals, so you have to look for the outcome of the body fat percentage.


Muscles are an active tissue which suggests that at rest they burn calories in a bigger proportion than fat. So, the male with more muscles will likely burn more calories at rest.


The lower the fat percentage the higher the muscle percentage.



To conclude, that the male with 13% of body fat will burn more calories at rest than the male with 29% of body fat.
