depends what you are trying to do and loads of stuff dose a chemical reaction.
Cells require enzymes, energy in the form of adenosine triphosphate (ATP), and specific substrates in order for chemical reactions to take place. Enzymes act as catalysts that speed up chemical reactions, while ATP provides the energy needed for these reactions to occur. Substrates are the molecules that enzymes act upon to initiate and facilitate the reactions.
yes chemical reactions in order to induce a chemical reaction that might normally take a long time
Chemical reactions do not require the written authorization of any human agency, to make them happen. They also do not require a favorable alignment of the stars. They do not need psychotherapy or marriage counseling in order to happen. There are infinitely many other things that they do not need.
The reactions that require oxygen to obtain chemical energy from glucose occur in the mitochondria of the cell. This process is known as aerobic respiration, where glucose is broken down in the presence of oxygen to produce ATP, the energy currency of the cell.
"They" would need to be defined in order effectively answer this question. In many cases mechanical devices that run on a chemical fuel require some form of priming in order to begin combustion.
Photosynthetic cells require chlorophyll, a pigment that absorbs light energy, and water to carry out the chemical reactions of photosynthesis. They also need carbon dioxide from the atmosphere to provide carbon for synthesizing organic molecules like glucose.
Endothermic reactions require energy to be absorbed in order to take place. This means that the reactions absorb heat from their surroundings in order to proceed.
Photosynthesis: The reaction where carbon dioxide and water are converted into glucose and oxygen by plants using sunlight. Endothermic reactions: Reactions that involve the absorption of heat energy from the surroundings, such as the decomposition of calcium carbonate to form calcium oxide and carbon dioxide.
Metabolism
l
Metabolism refers to all of the chemical reactions in the body that involve breaking down nutrients to produce energy or building up molecules for growth and repair. It is a crucial process for maintaining life and carrying out essential bodily functions.
There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. So I think they are Endothermic...
