Why would it be beneficial to couple an exergonic reaction with an endergonic reaction?
Coupling an exergonic reaction with an endergonic reaction allows the energy released from the exergonic reaction to drive the endergonic reaction, making it energetically favorable. This coupling enables cells to carry out important processes that would not occur spontaneously due to their energy requirements.
In cells endergonic reactions are often coupled with enzymatic reactions that store energy True or false?
True. Endergonic reactions, which require energy input, are often coupled with exergonic reactions that release energy through enzymatic processes. The energy released from the exergonic reaction is used to drive the endergonic reaction forward. This coupling allows the cell to maintain energy balance and perform various functions.
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.
Does the chemical equation of ATP release exergonic exothermic or absorb energy endergonic endothermic?
The breakdown of ATP into ADP and inorganic phosphate releases energy, making it an exergonic and exothermic reaction. This energy is used by cells for various cellular processes.
What it is called when food plus oxygen gas yields Carbon dioxide plus water plus cellular energy?
This process is called cellular respiration. In this process, food molecules react with oxygen gas to produce carbon dioxide, water, and ATP (cellular energy) which is used by cells for various functions.

What is the role of ATP in coupled reaction?
ATP is used as an energy carrier in coupled reactions. It provides the energy needed for endergonic (energy-requiring) reactions to proceed by transferring a phosphate group to the substrate, making it more reactive. This coupling of an exergonic (energy-releasing) reaction with an endergonic one allows cells to efficiently carry out their metabolic processes.
A chemical reaction that requires a net input of energy?
An example of a chemical reaction that requires a net input of energy is photosynthesis. In this process, plants use energy from sunlight to convert carbon dioxide and water into glucose and oxygen. The energy from sunlight is required to drive this reaction and is absorbed by chlorophyll in plant cells.

Which of the following statements about the role of ATP in cell metabolism is true?
The energy from the hydrolysis of ATP may be directly coupled to endergonic processes by the transfer of the phosphate group to another molecule. A key feature in the way cells manage their energy resources to do this work is energy coupling, the use of an exergonic process to drive an endergonic one. ATP is responsible for mediating most energy coupling in cells, and in most cases it acts as the immediate source of energy that powers cellular work.
What is source of electrical energy in galvanic cell?
The source of electrical energy in a galvanic cell is the chemical reaction that takes place between the two half-cells. This reaction creates a flow of electrons from the oxidation half-reaction to the reduction half-reaction, generating an electric current. The movement of electrons through an external circuit is what produces the electrical energy.
Is glucose a source of energy for brain cells?
yes, glucose is the only source of energy for brain cells
What is an exergonic reaction?
Exergonic reactions indicate a negative change in Gibbs free energy, which in English means that the reactions are spontaneous and do not require addition of energy. The exchange of oxygen and carbon dioxide in blood and lungs is an example. It is the concentration gradient that runs these exchanges passively, without additional energy from the cells.
How do cells carbohydrates?
Cells use carbohydrates as a source of energy and for energy storage.
What kind of cells have mitochondria?
