Describe the role of energy in chemical reactions?
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
Why do chemical reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
Which term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
The reactions that convert the energy in sunlight into chemical energy of ATP and NADPH?
Light Reactions.
Chemical reactions that energy often occur spontaneously?
endothermic: or energy absorbing reactions
Describe the role of energy in chemical reactions?

What describes the role of sunlight in chemical reactions?
it provides energy for some reactions to take place.
What is the role of energy in chemical reations?
All chemical reactions need a certain amount of activation energy to get started.
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
What energy is in chemical reactions?
Chemical energy
What reactions convert light energy to chemical energy?
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
Is chemical energy a source of electricity?
no, chemical energy is the energy released from chemical reactions
Chemical reactions that require energy?
endothermic reactions require energy
Why do chemical reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
Role of chlorophyll in photosynthesis?
Clorophyll collects the light energy that is used to fuel and start the chemical reactions for photosynthesis.
WHAT TERM DESCRIBES ENERGY THAT REQUIRES TO GET CHEMICAL REACTIONS STARTED?
Activation energy describes the energy that is required to get chemical reactions started.
Which term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
