Turning amino acids into molecules that can be used in the Krebs cycle takes energy, which means that burning protein for fuel is not as efficient as burning carbohydrates. ... When amino acids are used as an energy source, it reduces the reserves of amino acids that are available for protein synthesis.
In the winter its color changes to more resemble their <em>winter</em> surroundings, so they are more white, enabling them to blend in better with their white surroundings. In summer, its color changes to more resemble its <u><em /></u><em>summer</em> surroundings, so they are more brown like the rocks and ground around them.
I believe it's B. That would be the best guess
Answer:
The inducer will combines with the repressor and inactivates the pathway.
Explanation:
Inducer is a term in Molecular Biology, which represent a molecule or substance that has the capability to activate the transcription of a gene, where by it joins with and then inactivates a genetic repressor.
In other words, the inducer binds with the repressor in order to prevent the RNA polymerase to combine to the DNA, and chemically produce mRNA, this is done by repressor proteins combining with the DNA strand.
Inducer specifically makes repressor to change shapes, which will make it not combine with the DNA, and therefore, allow formation of transcription, such that expression of gene will eventually occur.
