Fatty acid synthase of mammalian cells: A) Uses a four-step sequence to lengthen a growing fatty acyl chain by one carbon B) Contains ACP, which carries acyl groups attached through thioester linkages C) Requires chemical energy in just one form: the reducing power of NADPH D) Is activated by glucagon and epinephrine E) Is activated by palmitoyl-CoA, the principal product of fatty acid synthesis

Explanation:

1. Fatty acid synthesis:   it is the  anabolic process though which the creation  of fatty acids occurs in the cell from the molecules like acetyl-CoA and NADPH.

2. Fatty acid synthesis occurs by the enzyme fatty acid synthases.

3. Most of the acetyl-CoA which is required for the synthesis of  fatty acids is derived from carbohydrates through the glycolytic pathway.

4. Fatty acid synthase of mammalian cell Contains ACP, which carries acyl groups attached through thioester linkages.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
