Answer: SECONDARY CELL WALL.
Explanation: When cell wall grow,it becomes thickened,then it further deposits new layers of a different material (different from that of the primary cell wall) from where secondary cell wall is formed.
This secondary cell wall is made up of cellulose,hemicellulose,and lignin.
They function in providing additional strength,support, rigidity to cells and the larger plant.
I think it is from the Paleozoic era
Hope this helps
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.
