What does deuterium and tritium make?

Deuterium and tritium are isotopes of hydrogen, the most abundant element in the universe. When deuterium and tritium fuse, they create a helium nucleus, which has two protons and two neutrons. The reaction releases an energetic neutron.

What is the difference of fission and fusion?

Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy. While different, the two processes have an important role in the past, present and future of energy creation.

What are Endoergic reactions?

endoergic reaction – a nuclear reaction occurring with absorption of energy. nuclear reaction – (physics) a process that alters the energy or structure or composition of atomic nuclei.

What does Endoergic mean?

: absorbing energy : endothermic endoergic nuclear reactions.

How are endergonic reactions and exergonics related?

In biochemical systems, endergonic and exergonic reactions often are coupled, so the energy from one reaction can power another reaction. Endergonic reactions always require energy to start. Some exergonic reactions also have activation energy, but more energy is released by the reaction than what is required to initiate it.

What’s the difference between an anabolic and exergonic process?

The building of complex molecules, such as sugars, from simpler ones is an anabolic process and is endergonic. On the other hand, the catabolic process, such as the breaking down of sugar into simpler molecules is generally exergonic.

How is the exergonic process related to thermodynamics?

Exergonic process. All physical and chemical systems in the universe follow the second law of thermodynamics and proceed in a downhill, i.e., exergonic, direction. Thus, left to itself, any physical or chemical system will proceed, according to the second law of thermodynamics, in a direction that tends to lower the free energy of the system,…

What happens to Gibbs free energy in an endergonic reaction?

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.
