Answer:
The third stage in the synthesis of fatty acids is the synthesis of palmitic acid (letter e)
Explanation:
The synthesis of fatty acids takes place in the cytoplasm of the cell. The first step is the transport of acetyl-CoA to the cytoplasm. This came in the form of citrate usually from the pyruvate generated in the glycolysis from the mitochondria. The citrate is enzymatically transformed into acetyl-CoA.
Once the acetyl-CoA is in the cytoplasm, this is transformed into malonyl-CoA. This molecule will be the donor of two carbons in the synthesis of fatty acids.
In the final step takes place a cyclic process of reactions (condensation, reduction, hydration and second reduction) to synthesize the palmitic acid ( 16 carbons) by the fatty acid synthase.
Answer:
Carbon
Explanation:
Most organic compounds contain carbon, hydrogen, and sometimes other elements such as nitrogen, sulfur, oxygen, or phosphorus. All living organisms contain carbon—even bacteria.
Oxygen, neccessary for cellular respiration, is the answer. As oxygen becomes scarce, your cells begin to aerobically produce very little ATP, in effect fermenting and producing lactic acid.
Answer: Cnidarians have a very simple sensory system that consists of a nerve net and no sensory organs. Octopi have a complex sensory system, including a brain and eyes as complex as human eyes.
