Why is photosynthesis considered an endergonic reaction?
The photosynthetic reaction is considered an endergonic reaction. In cells, endergonic reactions are often coupled with exergonic reactions that store energy. Why is photosynthesis considered an endergonic reaction? Low-energy reactants are converted to high-energy products.
Is photosynthesis Endergonic or Exergonic Why?
Photosynthesis is an endergonic process. Photosynthesis takes in energy and uses it to build carbon compounds.
Is photosynthesis an endergonic process?
An endergonic reaction is one that requires free energy to proceed. An example of an endergonic reaction of biological interest is photosynthesis. Photosynthetic organisms conduct this reaction by using solar photons to drive the reduction of carbon dioxide to glucose and the oxidation of water to oxygen.
Is photosynthesis an endergonic or exergonic reaction How do you know explain?
Photosynthesis is an endergonic (energy-consuming) process. Cellular respiration is an exergonic (energy-releasing) process.
What type of reaction is photosynthesis and why?
Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves. Chlorophyll is found in chloroplasts in plant cells, particularly the palisade and spongy mesophyll cells.
Is photosynthesis a spontaneous reaction?
An endergonic reaction (such as photosynthesis ) is a reaction that requires energy to be driven. Endergonic reactions are nonspontaneous.
Which type of reaction is photosynthesis?
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun’s electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant.
What is Endergonic vs Exergonic?
Exergonic and endergonic reactions result in changes in Gibbs free energy. In exergonic reaction the free energy of the products is lower than that of the reactants; meanwhile in endergonic the free energy of the products is higher than that of the reactants.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
Is Endergonic the same as endothermic?
Re: Exothermic vs Exergonic and Endothermic vs Endergonic Exo/ Endothermic represents the relative change in heat/enthalpy in a system, whereas Exer/ Endergonic refers to the relative change in the free energy of a system.
What are the two stages of photosynthesis?
Photosynthesis in the leaves of plants involves many steps, but it can be divided into two stages: the light-dependent reactions and the Calvin cycle. The light-dependent reactions take place in the thylakoid membrane and require a continuous supply of light energy.
What is the purpose of photosynthesis?
The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.
What is energy coupling?
energy coupling: Energy coupling occurs when the energy produced by one reaction or system is used to drive another reaction or system. endergonic: Describing a reaction that absorbs (heat) energy from its environment. exergonic: Describing a reaction that releases energy (heat) into its environment.
Is glucose breakdown Exergonic or Endergonic?
Breaking down glucose is an example of an endergonic reaction or an exergonic reaction.
What kind of reaction is respiration?
Respiration is an exothermic process. During respiration, glucose molecules are converted into a number of other molecules which in the end give CO2 and H2O.
