This drug inhibits the growth of bacterial cells but not human cells. This is an example of the selective toxicity of antibiotics.

Folic acid is an essential component for all cells to synthesize nucleic acids (DNA and RNA). Human cells do not synthesize folic acid and they take it through food. Bacterial cells are impermeable to folic acid and hence they need to synthesize their own folic acid.

Antibiotics target the metabolic pathway of folic acid synthesis in bacteria by inhibiting one of the enzymes in this pathway. These drugs are only toxic to bacteria but not to humans because humans do not have the folic acid synthesis pathway and hence they do not get affected by the action of the antibiotic. This is known as the selective toxicity of antibiotics.

These antibiotics are designed in a way to target the infecting agent (bacteria) while rendering minimal or no toxicity to the host (humans).

Cell theory states that all living things contain one or more cells. Why do you think cell theory meets the definition of
ziro4ka [17]

Answer:

Cell theory meets the definition of a scientific theory  because it can be proven, it has been tested for a long period of time and therefore there are many evidences that support the theory but not enough to become a law. Well scientific laws are statements based on repeated experiments or observation, but also, a law is something that always applies under the same conditions. Evolution occurs in the characteristics of living things within a species overtime. . A theory is much more complex: it explains why something happens. A law only describes what happens.

The cell theory meets the definition of a scientific theory but i do not think it should be a scientific law.

Free palmitate is activated to it's coA derivative(palmitoyl-CoA) in the cytosol before it can be oxidized in the mitochondria.
n200080 [17]

Answer: hydrolysis of intermediate palmitoyl Co A ,with loss of labeled CoA.before reaching the matrix gives the answer

Explanation:

This is because when the labeled Coenzyme A of the Plamitate combines as Palmitoy-CoA with oxaloacetate to form intermediate (palmitoyl-CoA )in Citric Acid cycle:

CoA is hydrolysed with loss of the labelled CoA which returns to the cystosol. Therefore, the labelled CoA does not reach the matrix of the mitochondrial,but returns to the Cystosol.

Consequently, the CoA in the Cystosol will be labelled in palmitoylCoA and the one in the matrix of the liver mitochondrial will be non radioactive(,will not labelled).
