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.

Explanation:
Plants living in the hot desert climate of Cairo are adapted to the desert climate by being able to survive several years without rain.
The atmospere doesnt contain enough oxygen and the temperature is way to cold
The cell you are examining under the microscope appears to contain a nucleus. This organism belongs to the domain <u>Eukarya</u>.
- The only domain that includes multicellular, visible organisms including humans, animals, plants, and trees is eukaryote.
- Numerous microorganisms, including fungi, algae, and micro-animals, also call it home. Since fungi are so diverse, two distinct fungi may have genetic differences comparable to those between a person and a fish.
- Eukarya are eukaryotes, which have organelles and nuclei that are bound to membranes. Prokaryotes are older, less numerous, and simpler than eukaryotes.
- Eukarya refers to creatures with nuclei in their cells. Additionally, it is the only realm in which multicellular observable organisms, such as people, animals, plants, and trees, exist. Achaea and bacteria are unicellular organisms without nuclei.

Answer:
The light reactions, also known as photolysis reactions, convert energy from the sun into chemical energy in the form of NADPH and ATP. These reactions must take place in the light and in chloroplasts of plants.
