Which area of the graph shows the activation energy required if an enzyme was not present
boyakko [2]

B

Area B of the graph shows the activation energy required if an enzyme was not present

Explanation:

Reactions with high activation energy cannot occur spontaneously. Enzymes are responsible for lowering this activation energy and enabling reactions to occur at a faster pace than natural. An example is carbonic anhydrase enzyme that enables increased rates of carbon dioxide dissolving in and out of blood plasma.

Enzymes distort the bond of reactants such that they become unstable ( this raises the reactants Gibbs free energy). The bonds therefore break and rearrange to form the products of lower and stable energy states.

To map genes of a bacterial strain, conjugation must be interrupted at given times. Suppose you have Hfr cells of genotype a+b+c
OLEGan [10]

Answer:

The answer is not in any of the options and is the following:

to eliminate any remaining Hfr cells.

Explanation:

In a medium that has a streptomycin antibiotic it is used to kill Hfr donor cells after the conjugation is interrupted. This is entirely due to the streptomycin sensitivity allele (str-s) which are found in Hfr strains. The presence of the streptomycin resistance allele, located in the receptor, is used for the specific destruction of Hfr donor cells after conjugation occurs.
