Answer:
a. they are central to the re-synthesis of nucleotides from bases in salvage reactions.
Explanation:
Phosphoribosyltransferases are the enzymes that are involved in salvage pathways to reuse the free purines and pyrimidines to make nucleotides. Metabolic degradation of nucleotides releases purines and pyrimidines which in turn enter the salvage pathway to be reused in the formation of new nucleotides. These metabolic pathways that make new nucleotides by reusing the free purines and pyrimidines are called salvage pathways.
Example: Adenosine phosphoribosyltransferase is the enzyme that catalyzes the formation of adenine nucleotide from free adenine and PRPP (5-phosphoribosyl-1-pyrophosphate).
The adult human body consists of 206 bones, however when you are born your body consists of 270 and over time some bones form together and you eventually end up with 206 as an adult
Sonar uses sound waves in order to detect and locate objects in the water. The speed and detectable range of sound waves are impacted by the medium they are travelling through. Ocean water, the medium that sonar travels through, includes characteristics such as temperature, density, and salinity. These elements affect the nature of the medium, and thus affect the sound waves used for sonar detection.
If you make the effort arm, or side that is being pushed down longer, less force would be needed because it would move a greater distance so B.
