Exocytosis is not a method of uptake, rather its a method of excretion.
The correct option is (B) Lysine.
The precursors glutamine (N2 and N9), glycine (C4, C5, and N7), aspartate (N1), co2 (C6), and folate are used to create the purine ring (C2 and C8). All are precursors to the purine ring, with the exception of lysine.
How is Purine synthesized de novo?
- In all cells, the cytosol is where purine biosynthesis takes place.
- There are 11 steps that are catalyzed by enzymes that build the purine ring. Each enzyme includes several monomers because it is oligomeric.
- The reaction does not release the intermediate products that are created. They are instead transported to the next enzyme in the process.
- The biosynthesis process in the human body can provide the body's need for purine in metabolic processes. Clinical symptoms might become unpleasant if purine synthesis is inadequate or if biosynthetic routes are aberrant.

Answer: Cell specialization or cell differentiation is a process of converting generic cells in the body into specialized cells. The specialized cells can perform a certain function within the body. The cell specialization occurs in two stages of a multicellular organism.

Answer:
Yes. If you're trying to solve a multiple choice question, you'll need to put in the answer choices, but here is what i think.
Explanation:
The Copernican Revolution gives us an important framework for understanding the Universe. The Universe and everything in it can be understood and predicted using a set of basic physical laws. The entire Universe obeys the same physical laws everywhere (and at all times).
