Explanation / Answer
An O-P bond in ATP is referred to as a "high energy phosphate bond". Which of the following statements are true about that bond?
-The bond is a particularly stable bond.
-The bond is a relatively weak bond.
-Breaking the bond (just breaking it; not including forming new bonds afterwards) releases a significant quantity of energy.
-A relatively small quantity of energy is required to break the bond
Answer = -The bond is a particularly stable bond.
A relatively small quantity of energy is required to break the bond
B. In the combustion of ethylene, C2H4(g) + 3O2(g) 2CO2(g) + 2H2O(g) (exothermic), which step(s) release energy?
-Breaking the C-C bond
-Breaking the C-H bonds
-Breaking the O-O bonds
-Forming the C-O and O-H bonds
Answer = -Forming the C-O and O-H bonds
