yes they all need more or less start up energy
Chemical reactions in living organisms require a source of energy to start. This energy is typically obtained from molecules such as ATP. Additionally, enzymes play a critical role in catalyzing these reactions by lowering the activation energy required for the reaction to occur.
No, not all chemical reactions require heat to start. Some reactions can occur at room temperature or even at low temperatures. Heat is often used to speed up reactions or provide enough energy to overcome the activation energy barrier.
Endothermic reactions need heat.
no
Candle and all Chemical reactions
All chemical reactions need a certain amount of activation energy to get started.
Candle and all Chemical reactions
Chemical reactions that absorb energy need an input of energy in the form of heat, light, or electricity to overcome the activation energy barrier and initiate the reaction. This added energy allows the reactant molecules to surpass their energy threshold and transition into a higher-energy state, leading to the formation of products.
A chemical reaction need an activation energy to start.
Light dependent reactions are reactions the capture light energy and convert it into chemical energy(ATP). It occur in the chloroplast of plant cells Light independent reactions are reactions capture energy and use it to produce food . It does not need sunlight
I wonder about a lot of things, yes.
Heat is a form of energy. All chemical reactions need to have an energy of some sort. Fire is a chemical reaction. You can figure out the rest. na sooooooo!
