Plasma Membrane is the answer
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
<em> B. Master genes do not </em><u><em>determine the organization of the genome</em></u><em>
.</em>
<em> C. </em><u><em>Regulation of cell metabolism</em></u><em> depends of substances as hormones and enzymes.
</em>
<em> D. </em><u><em>The rate of translation</em></u><em> does not depend on the activity of master genes.</em>
Chargaffs rules states that dna from any cell of all organisms should <span>have a 1:1 ratio (base Pair </span>Rule<span>) of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine.</span>
Answer:
During the oxidation of glucose in the liver the malate aspartate shuttle system is used, therefore, two additional ATPs get generated at the step constituting glyceraldehyde-3-phosphate dehydrogenase.
On the other hand, in the brain, a cell uses the glycerol phosphate shuttle system, which generates two less number of ATPs. However, the remaining of the energetics for the number of ATP in both cases are similar.
Thus, the difference is based upon the kind of shuttle system used that leads to the production of 32 ATPs in liver cells and 30 ATPs in the brain cells.
