Why are endergonic and exergonic reactions are said to be coupled in living cells?
Endergonic reactions absorb energy, while exergonic reactions release energy. In living cells, these reactions are coupled so that the energy released from exergonic reactions can be used to drive endergonic reactions. This coupling allows cells to maintain energy balance and perform essential functions.
Are exergoinic and endergoic reactions frequently coupled?
Yes, exergonic and endergonic reactions are frequently coupled in living organisms to efficiently transfer energy between processes. The energy released from an exergonic reaction can drive an endergonic reaction, allowing the cell to carry out necessary functions while maintaining energy balance.
Compare and contrast between exergonic and endergonic reactions?
Exergonic vs. Endergonic reactions: exergonic release more energy than they absorb. Endergonic reactions absorb more energy than they release.Exergonic reactions release energy while endergonic reactions absorb energy.
What is the relationship between exergonic reactions endergonic reactions and the use and regeneration of ATP?
Exergonic reactions release energy and are spontaneous, while endergonic reactions require energy input and are non-spontaneous. ATP is used to drive endergonic reactions by providing the necessary energy for them to occur. ATP is regenerated through exergonic reactions by capturing the energy released during these reactions.
How can an Endergonic reaction not be Endothermic?
An endergonic reaction is characterized by a positive change in Gibbs free energy, meaning it requires energy input to proceed. However, this does not necessarily mean it is endothermic, as endothermic reactions specifically absorb heat from their surroundings. An endergonic reaction could be driven by other forms of energy, such as light or electrical energy, rather than heat. Thus, while all endothermic reactions can be endergonic, not all endergonic reactions are endothermic.

Are endergonic reactions catabolic processes?
No, endergonic reactions are not catabolic processes. Endergonic reactions require energy input to proceed, while catabolic processes involve the breakdown of molecules to release energy.
What is the difference between endergonic and exergonic reactions in terms of energy changes?
Endergonic reactions require an input of energy to occur, while exergonic reactions release energy.
Does endergonic give energy?
Endergonic reactions require energy input to proceed, as they involve the absorption of energy from the surroundings. The endergonic process stores this energy within the system for chemical reactions or other forms of energy utilization.
Is the pathway b-c is coupled with ADP-atp catagorize the reactions as endergonic or exergonic?
ADP-ATP is endergonic and B-C is exergonic
What reactions are coupled in aerobic respiration?
In aerobic respiration, the reactions that are coupled include glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain. These reactions work together to break down glucose and produce ATP, the main energy currency of the cell.
Do endergonic reactions release energy?
No they do not. An endergonic reaction requires a net input of energy to force it to occur.
What is the relationship between exergonic reactions endergonic reactions and the use and regeneration of ATP?
Exergonic reactions release energy and are spontaneous, while endergonic reactions require energy input and are non-spontaneous. ATP is used to drive endergonic reactions by providing the necessary energy for them to occur. ATP is regenerated through exergonic reactions by capturing the energy released during these reactions.
How do energy carriers participate in coupled reactions?
Energy carriers like ATP can participate in coupled reactions by providing the necessary energy to drive an endergonic reaction (which requires energy input) by being hydrolyzed into ADP and inorganic phosphate, releasing energy in the process. This released energy can then be used to drive an exergonic reaction (which releases energy) by providing the required activation energy for the reaction to occur. In this way, energy carriers facilitate coupling reactions that require an input of energy.
Do endergonic reactions absorb more energy than they release?
Yes, endergonic reactions absorb more energy than they release. These reactions require an input of energy in order to proceed, and the energy absorbed is greater than the energy released during the reaction.
