Why do nuclear reactions release more energy than chemical reactions?
Nuclear reactions release more energy than chemical reactions because they involve changes in the nucleus of an atom, where much larger amounts of energy are stored compared to the energy stored in the electron shells involved in chemical reactions.
Pathways that have an overall energy requirement are referred to as?
Pathways that have an overall energy requirement are referred to as anabolic reactions.
What is the minimum energy requirement for a collision with proper alignment to be successful?
The minimum energy requirement for a collision to be successful depends on the specific reaction and molecules involved. Generally, colliding particles need to surpass the activation energy barrier to initiate a successful reaction. This energy is determined by the specific chemical bonds involved and the reaction mechanism.
How do objects produce energy and what are the mechanisms involved in this process?
Objects produce energy through various mechanisms such as chemical reactions, nuclear reactions, and electromagnetic interactions. In chemical reactions, bonds between atoms are broken and new bonds are formed, releasing energy in the process. In nuclear reactions, the nucleus of an atom undergoes changes, releasing large amounts of energy. Electromagnetic interactions involve the movement of charged particles, such as electrons, which can generate energy in the form of electricity. Overall, the mechanisms involved in energy production depend on the specific properties and composition of the object in question.
Why does nuclear reactions produce tremendous amounts of energy and what is the source of this energy?
Nuclear reactions produce tremendous amounts of energy because they release energy stored within atomic nuclei. This energy comes from the conversion of mass into energy, as predicted by Einstein's famous equation E=mc^2, indicating that a small amount of mass can yield a large amount of energy.
Why do nuclear reactions release more energy than chemical reactions?
Nuclear reactions release more energy than chemical reactions because they involve changes in the nucleus of an atom, where much larger amounts of energy are stored compared to the energy stored in the electron shells involved in chemical reactions.
Pathways that have an overall energy requirement are referred to as?
Pathways that have an overall energy requirement are referred to as anabolic reactions.
What requirement from the environments go into the light reactions?
light energy
What are slowed reactions?
Chemical reactions that have high activation energy, with multiple intermediates and transitions states that have higher activation energy than the initial requirement, but which still have a negative Gibbs free energy change.
Explain in general terms how redox reactions are involved in energy exchanges?
Redox reactions involve the transfer of electrons between species. When a substance is oxidized, it loses electrons, and when it is reduced, it gains electrons. These electron transfers are often associated with the release or absorption of energy, making redox reactions important in energy exchanges within biological systems such as cellular respiration and photosynthesis.
Why energy requirement at different stages of life is different for the same individual?
This is because as people grow they require more energy. Also, a person's energy requirements differ depending on the kinds of activities they are involved in.
Which pigment is directly involved in the light reactions of photosynthesis?
The pigment directly involved is the green pigment called 'chlorophyll' and is found in the chloroplats.
What electromagnetic wave has its origin in the nucleus of an atom?
In nuclear reactions, energy is usually released. This energy is released as an electromagnetic wave. Because of the large amount of energy involved, this wave has a high frequency/energy - a gamma ray.
The electrons that are in the highest energy level of an atom and that are involved in chemical reactions?
valence electrons

This energy is determined by the specific chemical bonds involved and the reaction mechanism.
Is energy always involved in making or breaking chemical bonds?
no, some reactions are spontenous.
What are the electrons that are in the highest energy level of an atom and that are involved in chemical reactions?
Valence electrons
