Is energy conversion accomplished in the light reaction phase?
light reactionthe photochemical phase of photosynthesis in which light energy is converted and stored biochemically in the form of ATP
Is activation energy for thermal and photochemical reactions same?
The definition of the activation energy is exactly the same -- the thermodynamic energy barrier that the reactant must pass over to convert to products. The difference between a thermal and a photochemical reaction is only where the reactants get the energy to get over this barrier. In a thermal reaction, that energy is given by the temperature, and is carried in excited rotational modes, higher kinetic energies and if hot enough, excited vibrational states. In a photochemical reaction, the activation energy is provided by photons, usually in the form of electronic excited states, but could also be vibrational or rotational. The concept of the activation barrier is identical in both cases.
Energy is lost from a reaction in a form of what?
energy of a reaction will be lost in the form of heat.
Whet is light reaction process?
The light reaction can accomplish three things. Firstly, photoexcitation, basically what occurs in this process is the electron of chlorophyll absorb specific wave lengths of light. Secondly, we have electron transport, which pumps hydrogen to create a gradient that powers the ATP synthesis. And lastly there is chemosmosis, which is the movement of protons through ATP synthase complex that drives the phosphorylation of ATP.
In what form is the energy released in this reaction?
In an exothermic reaction heat energy is released.
A form of energy that can stimulate a reaction?
Heat energy can stimulate a chemical reaction.
Free energy is the minimum energy necessary for product to form?
False, the minimum reaction energy needed for a reaction to form or take place is called the activation energy.
What is a reaction that releases energy in the form of heat?
Exothermic reaction
Chemical energy is energy that is?
added to a reaction in the form of heat.
What is the form of energy that drives the displacement of water in the tides?
That form of energy is gravity.It is the gravity from the moon wich attracts the water.
Reaction that absorbs energy in the form of heat?
Endothermic.
How is photochemical created?
There are two major types of smog: photochemical and industrial smog. Photochemical smog is created through a reaction by which air pollutants are struck by sunlight, and form particulate matter and tropospheric ozone. The air pollutants that are most responsible for this type of smog are nitrogen oxides (NOx) and volatile organic compounds (VOCs). Photochemical is especially a problem in areas with many cars, coal-burning power plants, and the right weather conditions. Los Angeles, CA is a city that often has to deal with photochemical smog.
