100% of the free energy in glucose is converted into ATP energy
|
|
|
cellular respiration is exergonic
|
Detailed explanation-1: -Cellular respiration is a process in which glucose molecule is digested to generate chemical energy or ATP for the cells. Therefore, it is an exergonic reaction that has negative free energy change or negative delta G. Therefore, the correct option is d.
Detailed explanation-2: -Cellular respiration is an exergonic (energy-releasing) process.
Detailed explanation-3: -It releases energy in steps, each step is coupled with the synthesis of ATP. Only a small amount of energy dissipates as heat. Therefore, we say that the cellular respiration is an exergonic process because in this the energy is released.
Detailed explanation-4: -An exergonic reaction (such as cellular respiration) is a reaction that releases free energy in the process of the reaction. The progress of the reaction is shown by the line. Activation energy (1) slows down the reaction.
Detailed explanation-5: -Catabolism refers to the exergonic process by which energy released by the breakdown of organic compounds such as glucose can be used to synthesize ATP, the form of energy required to do cellular work.
