<span> The right answer is </span><span> c. human activity. Phosphorus cycle takes place even without human involvement but it can still affect or cause major changes in this nutrient cycle. </span>Humans use fertilizers and raise livestock (hogs). Waste from livestock and fertilizers are high in phosphate that gets into the soil and bodies of water through drainage and run-off.
Answer:
Photosynthesis adds carbon dioxide to the air
Explanation:
The correct answer is the last statement.
If the regulatory serine is mutated to alanine, then acetyl-CoA carboxylase will get activated spontaneously and will produce malonyl-CoA. The increased concentrations of malonyl-CoA will obstruct the oxidation of fatty acids by preventing the entry of fatty acids into the mitochondria.
It is because the AMP-activated protein kinase phosphorylates the serine residues of acetyl-CoA carboxylase to inactivate it. If a mutation occurs in such residues, then the AMPL cannot phosphorylate acetyl-CoA carboxylase and this enzyme will get activated spontaneously.
In such a situation, there will be more than sufficient production of malonyl-CoA, which will inhibit the admittance of more fatty acid getting inside the mitochondria; this will indirectly prevent the oxidation of fatty acids.
