During photosynthesis, a plants chlorophyll underoges a chemical reaction with minerals, sunlight, and all the water it takes in to form sugars to stay alive!
Energy
You need to get the reaction above its activation energy before it will start.
Endothermic reactions need heat. Exothermic reactions give off heat.
If your question is ''What causes the activation energy required in a chemical reaction to lower down?'' Then my answer to your question would be that the temperature factor is either more than to what the enzymes needed or less than what is needed by the enzymes to function. However the optimum temperature mostly for an enzyme to be active at the fullest can be till 40 degrees Celsius.
An 'exothermic' reaction gives of energy, and an 'endothermic' reaction absorbs energy.
A chemical reaction need an activation energy to start.
in their food that has chemical energy inside.
They have a specific reactivity and the reaction need an activation energy.
Energy
Any chemical reaction need an activation energy to occur.
For example any chemical reaction need an activation energy.
Any chemical reaction need an activation energy.
Plants store chemical energy in sugar molecules. Plants go through photosynthesis in order to grow and store the food they need.
Land plants generate the energy they need for their metabolic energy by converting their light energy to metabolic enrgy or so called chemical energy.
In some cases.
You need to get the reaction above its activation energy before it will start.
All the plants, who need photosynthesis for a chemical reaction to light energy, will need Magnesium. Magnesium is classified as an alkaline earth metal. It is the 8th most frequent element found in the Earth's crust. Its an elaborated issue. All plants need Chlorophyl to be transferred to energy (sun light) will need the help of Magnesium.
