Answer: B (GTP serves as the energy input for AMP synthesis from IMP)
Explanation:
In the de novo synthesis of purine nucleotide, IMP represents a branch point for purine biosynthesis. IMP can be converted to either AMP or GMP.
The formation of AMP from IMP requires GTP; similarly formation of GMP requires ATP. The conversion of IMP to either AMP or GMP is highly regulated – AMP and GMP inhibits their own formation by feedback inhibition of adenlyosuccinate synthetase and IMP dehydrogenase.
Diffusion is used. Diffusion is one principle of moving of cells
I think it’s B having second thoughts

Answer: a reaction in which energy is absorbed from the surroundings is called an endothermic reaction
Explanation: in in document reactions the enthalpy of the products is greater than the empathy of the reactants. exothermic reactions heat up their surroundings while endothermic reactions cool them down
