Photosynthesis
Plants have to utilize solar energy during photosynthesis because it is needed to create the chemical reaction. This reaction produces glucose and oxygen.
These are the metabolic reactions.
Yes and no. Yes before the reaction, No after the reaction.There is potential chemical energy among constituent substances in an exothermic reaction - such as in Hydrogen and Oxygen. When the chemicals combine, the reaction liberates thermal energy that was stored as potential chemical energy before the reaction.During the chemical reaction, the potential energy is converted into thermal (and perhaps other forms, such as light) energy.After the chemical reaction, the thermal energy is disspiated, and the potential energy is gone.
The spark is the activation energy. It is the catalyst of the chemical reaction.
Basically Chemical Energy is stored up in the bonds. Chemical energy is usually converted to another form sucha sheat and light. Burning magnesium produces haet and light. The chemical energy is stored in the metal and the oxygen. It has a scientific name of chemical potential.
glowing splint ... if it relights then the chemical reaction produces oxygen.
Respiration
Plants have to utilize solar energy during photosynthesis because it is needed to create the chemical reaction. This reaction produces glucose and oxygen.
Chemical potential energy. Fire is a chemical reaction caused by heat Fuel and oxygen (usually) The fuel is combusted exothermically (ie giving off heat) with oxygen which is a chemical reaction. This causes surrounding fuel to heat up a react exothermically with the oxygen, propagating the fire.
The reaction between oxygen and hydrogen produce water.
H2O CO2 and Energy in Animal cells. O2, Glucose and energy in plant cells
This chemical reaction is called photosynthesis.
Everything that your body does, from the beating of your heart to the thoughts in your brain, depends upon a series of chemical reactions. The basic reaction which produces the energy needed to drive all the other reactions is the reaction of sugar and oxygen. Without that, everything stops.
These are the metabolic reactions.
Aerobic respiration is the process.Oxygen is needed in electron transport chain.
Through oxidation. That is to say, a chemical reaction that involves oxygen.
Yes and no. Yes before the reaction, No after the reaction.There is potential chemical energy among constituent substances in an exothermic reaction - such as in Hydrogen and Oxygen. When the chemicals combine, the reaction liberates thermal energy that was stored as potential chemical energy before the reaction.During the chemical reaction, the potential energy is converted into thermal (and perhaps other forms, such as light) energy.After the chemical reaction, the thermal energy is disspiated, and the potential energy is gone.
