Question

Most reactions of fatty acid synthesis occur in.

• A. The cytosol, the mitochondrion, the plastid and the E.R.
• B. The mitochondrian, the plastid and the ER.
• C. The glyoxysome, the mitochondrion and the E. R.
• D. The plastid only

Answer 1

The correct option is A The cytosol, the mitochondrion, the plastid and the E.R.

Fatty acid biosynthesis in plants occurs in the plastids of non-photosynthetic tissues and in animals this process takes place in the cytosol of the cell, mitochondria and in endoplasmic reticulum. Fatty acid synthesis is the creation of fatty acids from acetyl-CoA and NADPH through the action of enzymes called fatty acid synthases.

So, the correct option is 'A'.
