<span>Most X-linked conditions are recessive. This means that in a person with two X chromosomes (most females), both copies of a gene (i.e., one on each X chromosome) must have a change or mutation whereas in a person with one X chromosome (most males), only one copy of a gene must have a mutation. A female with a mutation in one copy of a gene on the X chromosome is said to be a “carrier” for an X-linked condition</span>
Answer:
The correct answer will be- the free energy change will be +13 kcal/mol.
Explanation:
The free energy change of a chemical reaction is the measure of the spontaneity of the reaction in which the negative value of free energy represents that reaction is exergonic while positive value represents that reaction is endergonic.
In the given question, if the free-energy change is 13 kcal/mol for the hydrolysis of ATP to ADP + Pi which releases energy used by the cells then reversal of the reaction that is the formation of ATP molecules from the ADP and Pi requires energy which will be the same energy required to break the ATP.
This shows that 13kcal/mol energy will be used but with a positive sign as the energy is needed or the reaction is endergonic.
