for every reaction there is a minimal amount of energy required. sometimes this amount of energy is provided by the environment and sometimes not. when the energy is not provided by the environment heating is required. all of this is a result of the collisions of atoms .they need energy to form products with other atoms. this energy is obtained from the environment
What else can I help you with?
What are the exothermic and endothermic reactions and how can they be used?
exothermic reactions are those that give out energy (most notably by heat) when they occur endothermic reactions require energy to take place and thus feel cold to touch as they extract heat from the surrounding environment.
Chemical reactions that require energy?
endothermic reactions require energy
Do all reactions release energy?
No, not all reactions release energy. Some reactions require an input of energy to proceed, and these are called endothermic reactions. Endothermic reactions absorb heat from the surroundings rather than releasing it.
Is it true or false that all chemical reactions require an initial input of energy called catalysis?
False. Not all chemical reactions require catalysis. Some reactions occur spontaneously, while others may require an initial input of energy in the form of activation energy. Catalysis is a process that lowers the activation energy required for a reaction to occur, but it is not necessary for all reactions.
Is heat liberated in endothermic reactions?
No. Heat is given out (liberated) in exothermic reactions not endothermic. exo = out, therm = heat. Endothermic reactions take in heat energy from the surrounding wshich cause the surrounding temperature to decrease. endo = in.
How are anaerobic and aerobis reactions different?
Anaerobic reactions happen in the cytoplasm of a cell, Aerobic reactions occur in the mitochondria of a cell Anaerobic reactions do not require oxygen, Aerobic reactions do require oxygen
Do anabolic reactions require energy to build complex molecules?
Yes, anabolic reactions require energy to build complex molecules.
Why do some chemical reactions release heat while others absorb heat?
Chemical reactions release or absorb heat based on whether they release or require energy to break or form bonds between atoms. Reactions that release heat are exothermic, as they release energy, while reactions that absorb heat are endothermic, as they require energy input.
Do dehydration reactions require ATP?
Dehydration reactions typically do not require ATP because they involve the removal of water molecules to form new bonds. However, some dehydration reactions that involve the synthesis of complex molecules may require ATP as an energy source for the process.
What do most of the chemicals reactions involved in metabolism require?
They actually require Water.
What does chemical reactions of metabolism require?
nutrients
What do chemical reactions in the metabolism require?
nutrients
