72 chromatids were present in the present in the primary oocyte during  prophase 1 of meiosis.

The primary oocyte contains 72 chromatids during prophase 1 of meiosis as the mature ovum has 18 chromosomes.

The primary oocyte contains 72 chromatids , that means it contains 144 chromosomes. During the first meiotic division, it produces one secondary oocyte and one polar body.

The secondary oocyte  has 72 chromatids, which again undergoes second meiotic division and produces mature ovum and second polar body . The mature ovum contains contains 36 chromatids which means it has 18 chromosomes.

<h2>Fatty acid oxidation </h2>

Explanation:

  • Activation of fatty acids (palmitate) occurs in the cytoplasm where fatty acids are activated to fatty acyl CoA, reaction catalysed by an enzyme called fatty acyl CoA synthetase
  • A specialized carnitine carrier system catalyze transportation of activated fatty acid from cytoplasm to matrix of mitochondria, where carnitine system consists of three proteins:
  • Carnitine acyl transferase I located in outer membrane of mitochondria catalyze transfer of carnitine to fatty acyl CoA and produce fatty acyl carnitine
  • Carnitine translocase facilitate passive diffusion of fatty acyl carnitine from inter membrane space to matrix located in inner membrane
  • Carnitine acyl transferase III located in inner mitochondrial membrane at matrix phase catalyze transfer of CoA to fatty acyl carnitine and regenerate fatty acyl CoA

Hence, the cytosolic and mitochondrial pools of CoA are thus kept separate, and no radioactive CoA from the cytosolic pool enters the mitochondria

What statement is true about macromolecules?
sammy [17]
Macromolecules like carbs, protein and lipids (fats) are made of smaller molecules like simple sugars (carbs), amino acids (protein), or fatty acids (lipids). These molecules must be broken down to be used.

Let me know if you need further elaboration, I took human nutrition last semester. :)
