NADPH, which is reduced, is in a high form of free energy. Its low from of free energy is NADP+, which is oxidized. NADPH reaches its high state of free energy through the light reaction phase of photosynthesis. After photosystem 1 (PSI) Fd, which is an electron acceptor, reduces NADP+ turing it into NADPH by adding one proton (H+) and two electrons on to it. It is a more versatile energy source during the Calvin Cycle, the second stage of photosynthesis, than water because it has higher free energy and its energy is more accessible.
What else can I help you with?
How much energy is available at room temperature?
At room temperature (~20-25°C), the available energy is typically in the form of thermal energy. The amount of energy available can vary, but it is generally low compared to other forms of energy such as chemical or electrical energy.
How does the relationship between ionization energy and reactivity of metals influence their chemical properties?
The relationship between ionization energy and reactivity of metals affects their chemical properties. Metals with low ionization energy are more reactive because they can easily lose electrons to form positive ions. This reactivity influences how metals interact with other substances and their ability to undergo chemical reactions.
How Transformation of low energy reactants into high energy products?
During a chemical reaction, energy is either absorbed or released. In an endothermic reaction, energy is absorbed to convert low-energy reactants into high-energy products. In an exothermic reaction, energy is released as high-energy reactants are transformed into low-energy products.
How does ionization energy affect the reactivity of metal?
Ionization energy is the energy required to remove an electron from an atom. A lower ionization energy means it is easier to remove electrons, making the metal more reactive. This is because metals with low ionization energy are more likely to lose electrons and form positive ions in chemical reactions.
A factor that slows down a chemical reaction?
A factor that can slow down a chemical reaction is a low temperature, as lower temperatures reduce the kinetic energy of the reacting molecules, leading to fewer collisions and a slower rate of reaction.
What form of energy does a headphones use?
AC current, low voltage.
What is the lowest form of energy?
The lowest form of energy is considered to be thermal energy, or heat energy. This form of energy is often less useful for performing work compared to other forms of energy like mechanical or electrical energy.

What does it mean for a chemical to have a low potential energy?
It means that this chemical may react with other chemical species quite easily.

Where do plants store chemical energy?
Plants store chemical energy in the form of glucose molecules, which are produced through photosynthesis. Glucose is stored in various plant parts such as roots, stems, and seeds, where it can be used for energy production during periods of low light or other stress conditions.
Do an atom's valence electron have high or low energy?
Valence electrons generally have higher energy compared to core electrons because they are located in the outermost shell of an atom and are involved in chemical bonding. Their higher energy allows them to be more easily lost or shared during chemical reactions. This makes them crucial for determining an atom's reactivity and the types of bonds it can form.
Why is energy efficiency of biological systems very low?
Energy efficiency in biological systems is low due to the inherent inefficiency of converting one form of energy to another, such as from chemical to mechanical energy. In addition, biological systems often prioritize other functions, such as growth, reproduction, and maintaining homeostasis, over maximizing energy efficiency. Lastly, evolutionary constraints and trade-offs may limit the optimization of energy efficiency in biological systems.
What type of material do atoms form when they are close together and have low energy?
When atoms are close together and have low energy, they typically form solids. In solid materials, such as metals, the atoms are tightly packed together in a regular pattern, allowing them to vibrate only slightly. Atoms in solids have a stable arrangement and exhibit strong interatomic forces, resulting in a rigid structure.
What is low ionization potential?
A low ionization potential refers to the amount of energy needed to remove an electron from an atom or molecule. Atoms with low ionization potentials tend to lose electrons easily and are more likely to form positive ions. This property is important in determining reactivity and chemical behavior.
Why is energy is requried to synthize carbohydrates from simple compounds?
1) Carbon dioxide and water are the raw materials which are converted into gluco-se.2) Generally these are the substances of low energies in them.3) So,they require energy to form chemical bonds between atoms of simplecompounds.4) This energy is observed in the form of sun light.'------------------------------------------------------Given by:Maniteja RayabarapuEmail:-maniteja.rayabarapu@gmail.com
