What else can I help you with?
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.
Do anabolic reactions release energy while building polymers?
no. Anabolic reactions require energy...they are endergonic.
Different chemical reactions take different amounts of what?
Energy. Different chemical reactions require different amounts of energy to occur, which can affect the speed and extent of the reaction.
Chemical reactions that absorb energy will not occur without a source of energy true or false?
This is true. Energy is required to begin all reactions.
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.
What does cells require in order for chemical reactions to take place?
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.
What is the relationship between the temperature and the rate of chemical?
Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
What energy is in chemical reactions?
Chemical energy
Most of the chemical reaction involved in metabolism require what?
Most of the chemical reactions involved in metabolism require enzymes as catalysts to speed up the reactions. These enzymes help to lower the activation energy needed for the reactions to occur. Additionally, these reactions often require specific substrates and cofactors to proceed efficiently within the cells.
What are the chemical reactions that take place in a cell that involve energy?
In a cell, chemical reactions that involve energy include cellular respiration, where glucose is broken down to produce ATP, the cell's energy currency. Another key reaction is photosynthesis, where light energy is converted into chemical energy in the form of glucose. Both processes involve complex series of reactions that require and release energy.
What do chemical reactions in living organisms need to start?
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.
