-30.5 kJ/mol
-14 kcal/mol
-7.3 kcal/mol
What is the role of ATP in reaction coupling?
It acts as a catalyst
It stabilizes the reaction
It provides energy through phosphorylation
It acts as a reactant
Let's make sucrose: What is the shared intermediate in ATP reaction coupling?
ADP
Pi
Sucrose
Phosphorylated glucose-P molcule
What is the ΔG for the formation of sucrose from glucose and fructose?
-7.3 kcal/mol
+14 kcal/mol
-30 kJ/mol
+27 kJ/mol
Why is ATP considered unstable?
Because it is a large molecule
Due to its low energy content
Due to its high energy bonds
Because it is a protein
Which of the following is true? (Generally speaking, in Chemistry, when it comes to isolated bonds)
Bond breaking is exothermic
Bond breaking is endothermic
Bond breaking decreases entropy
Bond breaking is always endergonic
In your own words: Why is the hydrolysis of ATP releasing energy, even though bond breaking in itself is endothermic (requires energy)?
