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.

Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
Is carbon dioxide a solution compound or element?
CO2 is a compound of carbon and oxygen, very stable, in a state of low chemical energy, with very little value.
What happens when an electron moves from a low energy state to a high energy state?
when an electron moves from low energy state to high energy state , it gains energy.
Does sodium have a low or high ionization energy?
low
When a person gets hypothermia the enzymes in their body become less active how does this change affect the body's chemical reaction?
most chemical reactions require a certain input of energy, meaning they need to be at a certain temperature. when the temperature is too low or too high, these chemical reactions cant take place.
What form of energy does a headphones use?
AC current, low voltage.
Why ions with charges greater than 3 are seldom found in ionic compounds?
This is because the ionisation energy is too large for releasing the third electron to form chemical compounds or the electron affinity is too low for gaining the third electron when forming a chemical compound which will result in a low lattice energy to stabilise the ion.
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.
What is the lowest form of energy?
The low quality energy refers to the dispersed and diffused energy at a very low temperature. The low quality energy is very difficult to collect and use for productive purposes. Anything related to heat is low quality energy.
What kind of setting does a low energy quiet environment provide for?
A low energy, quiet environment provides an ideal setting for sedimentary rocks to form.
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.
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
The activation energy for the chemical reaction in living thing is high or low?
It is high because the enzymes in cells speed up the reactions by lowering the energy.
Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
Why do cations form?
metals have high electropositivity and low ionisation energy. So they tend to form cations easily.
What can be converted to energy?
Anything with potential difference could create the flow of energy. A potential difference could be electropotential, chemical potential or potential difference between high and low ground like energy from water fall. A potential difference can exist in the form of motion difference between a stationary and a moving objects.
What is the difference between high efficiency and low efficiency?
Efficiency describes how well a device transfers one form of energy to another form of usefull energy. High efficiency transforms most of the energy with very little loss. Low efficiency only transforms a small amount into usefull energy and the rest is usually lost to heat energy from friction. For example, a car is a low efficiency device because only a small amount (I forget the actual number. Probably around 50%) of the chemical energy in gasoline actually gets converted to energy of moving the car. The rest is lost to air resistance, friction between all the moving parts & and unused heat out the exhaust pipe.
