Lab report on mass and motiom golf ball, rubber ball, plastic ball
Tasya [4]

Answer:

Mass and density in the increasing order among the mentioned balls are as follows: golf>rubber>plastic whereas Motion of rubber ball is higher than of golf and plastic ball due to elasticity of the rubber.

Moment of inertia of the ball is dependent on the mass and velocity of the balls which in turn will determine the motion of the balls. Elasticity property of the rubber ball will help to provide opposite force and can enhance the motion of the rubber ball as compared to golf or plastic balls.

The ____ ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the
maxonik [38]

Answer:

The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.

Explanation:

In the de novo synthesis of nucleotides, their metabolic precursors such as aminoacids, ribose-5-phosphate, CO₂ and NH₃ are used as starting materials.

In purine  nucleotide synthesis, the ring structure is built up on ribose-5-phosphate of PRPP by addition of one or a few atoms one at a time starting with the amino group donated by glutamine until the first intermediate inosinate is synthesized.

In pyrimidine ring synthesis, orotate is first synthesized from carbamoyl phosphate and aspartate, and then is attached to ribose-5-phosphate of PRPP, before it is then converted to the common pyrimidine nucleotides starting from uridylate.
