In animals, if the fuel consumed exceeds energy expended, fats are synthesized from carbohydrates in order to store the excess energy. Acetyl-coA Carboxylase catalyzes the first dedicated step in fatty acid synthesis. This enzyme responds to a large number of cellular signals. A logical strategy for the regulation of Acetyl-coA Carboxylase might include:

B) Activation when the concentration of AMP is low vs concentration of ATP

Explanation:

The ACC enzyme is reserved by the AMP i.e. activated protein kinase (AMPK)

at the time when the AMP concentration is high because it represent the energy is deficit in the cell while on the other hand the lower AMP versus ATP concentration represent that the surplus energy i.e. stored

So ACC enzyme could be activated

Therefore the option b is correct

all answers true and false

explanation:

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
