What is an exergonic reaction in biology?


Sharing is Caring


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.

What is a biological example of an exergonic reaction?

The example of exergonic reactions occur in our body is cellular respiration: C6H12O6 (glucose) + 6 O2 -> 6 CO2 + 6 H2O this reaction release energy which is used for cell activities. However, some exergonic reactions do not occur spontaneously and require a small input of energy to start the reaction.

What reactions are exergonic?

An exergonic reaction is a reaction that releases free energy. Because this type of reaction releases energy rather than consuming it, it can occur spontaneously, without being forced by outside factors. In chemistry terms, exergonic reactions are reactions where the change in free energy is negative.

What is exergonic and endergonic reaction?

Complete answer: An exergonic reaction is a type of spontaneous reaction where there is ‘release ‘ of free, here free energy is negative (less than zero). On the contrary, endergonic reactions are the reactions where energy enters the system, the free energy here is positive (greater than 0).

What is an endergonic reaction in biology?

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 DNA synthesis an endergonic or exergonic reaction?

DNA synthesis is a highly exergonic process due to the hydrolysis of the nucleotide.

Which reactions are exergonic quizlet?

  • exergonic reaction. a chemical reaction that releases energy.
  • cellular respiration is an. exergonic reaction.
  • endergonic reactions. yield products that are rich in potential energy.
  • endergonic. energy inward.
  • photosynthesis is an. endergonic reaction.
  • metabolism.
  • metabolic pathway.
  • energy coupling.

Which of the following is true for exergonic reactions?

The correct answer is (B) The reactions proceed with a net release of free energy. (B) The reactions proceed with a net release of free energy.

Which type of reaction requires ATP endergonic or exergonic?

Adenosine triphosphate (ATP) is the energy currency for cellular processes. ATP provides the energy for both energy-consuming endergonic reactions and energy-releasing exergonic reactions, which require a small input of activation energy.

Do endergonic reactions require energy?

Endergonic and exergonic reactions Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. Reactions with a positive โˆ†G (โˆ†G > 0), on the other hand, require an input of energy and are called endergonic reactions.

What causes an exergonic reaction?

Exergonic reactions are chemical reactions that release energy in the form of heat. Typically, this energy is released when bonds are broken. More specifically, in humans, these reactions are called catabolic, which means that the molecules are being broken down into smaller components.

What is the difference between exergonic and endergonic reactions quizlet?

What is the basic difference between exergonic and endergonic reactions? Exergonic reactions release energy; endergonic reactions absorb it. Exergonic reactions involve ionic bonds; endergonic reactions involve covalent bonds.

What is the difference between exergonic and exothermic reaction?

Exothermic” literally means “outside heating” while “exergonic” literally means “outside work.” Some examples of exothermic reactions are: combustion of fuels such as wood, coal, oil, and petroleum, condensation of rain from water vapor, and mixing of alkalis and acids.

What’s the meaning of exergonic?

exergonic. / (หŒษ›ksษ™หˆษกษ’nษชk) / adjective. (of a biochemical reaction) producing energy and therefore occurring spontaneouslyCompare endergonic.

Is photosynthesis an endergonic or exergonic reaction?

Photosynthesis is an endergonic (energy-consuming) process. Cellular respiration is an exergonic (energy-releasing) process.

Which type of reaction is endergonic quizlet?

In endergonic reactions, the reaction gains energy and in exergonic reactions, the reaction loses energy. What are some examples of endergonic reactions? Anabolism is an endergonic reaction because the build-up of more complex molecules results in the storage of energy. You just studied 9 terms!

What is the difference between endergonic and exergonic reaction process cite an example?

These two types of reactions have opposite definitions and properties. The main difference between endergonic and exergonic is that endergonic reaction requires energy from outside whereas exergonic reactions release energy to the outside.

Why is DNA An exergonic process?

DNA replication is a exergonic process because of the hydrolysis of nucleotides. Monomers that serve as substrates in the reaction are deoxyribonucleoside triphosphates (dNTPs), which have a high potential energy due to their three closely packed phosphate groups, so DNA polymerization is exergonic.

Why is DNA synthesis endergonic?

DNA replication is energy consuming process as new bonds are being formed. So, are endergonic and the energy is obtained form dNTP. Q.

Is RNA synthesis exergonic?

The reaction is extremely exergonic; i.e., it liberates much free energy as heat.

What is endergonic quizlet?

endergonic reaction. a non-spontaneous chemical reaction, in which free energy is absorbed from the surroundings.

What is an example of endergonic reaction quizlet?

The burning of sugar is an example of an endergonic reaction, and photosynthesis is an example of an exergonic reaction.

What do endergonic reactions require?

Endergonic reactions require energy input to take simple, low energy reactants and build complex, high energy products. Exergonic reactions release the energy bound up in the reactants and yield simpler, low energy products.

Which of the following best describes the term exergonic for a reaction?

Which of the following statements best describes an exergonic reaction? The reaction proceeds with a net release of free energy.

Which of the following is an example of an endergonic reaction?

Photosynthesis. One of the most common examples of an endergonic reaction is the process of photosynthesis. Photosynthesis is used by all plants to convert light energy into a form of chemical energy that can be used to fuel their life processes.
