Answer:
The cytosolic and mitochondrial pools of CoA are kept separate, and no radioactive CoA from the cytosolic pool enters the mitochondrion.
Explanation:
- Fatty acyl group condensed with CoA in the cytosol are first transferred to carnitine and in this process, CoA is released.
- After this, it is transported into the mitochondrion, where it is again condensed with CoA.
- In this way, the cytosolic and mitochondrial pools of CoA are kept separate, and due to this reason, no radioactive CoA from the cytosolic pool enters the mitochondrion.
- Therefore, according to the given question, the C14 CoA that is added into the liver homogenate along with palmitate shows cytosolic radioactive fraction but not mitochondrial as in the mitochondria a different CoA joins palmitate and not the one containing C14.
Answer:
1. Nucleoid
2. Plasmid
Explanation:
Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.
However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.
Autotrophs and Hetrotrophs
