chemical energy (from molecules such as saccharides, fats, proteins we eat) that is transformed into ATP (Adenosine Triphosphate) in cell respiration (glycolysis, Krebs' Cycle and Electron Transport Chain).
Whenever a pump at a cell membrane wants to get a substance in low concentration to an area of high concentration, it makes molecules of ATP bind to it, these ATP molecules split into ADP (AdenosineDIphosphate) + Pi and therefore release this very chemical energy that was stored in cell respiration. Eventually, it is this energy that also makes the pump work.
What else can I help you with?
What kind of energy do enzymes reduce?
Enzymes reduce activation energy, which is the energy required to start a chemical reaction. By lowering the activation energy, enzymes make reactions occur more readily and at a faster pace.
What is activation energy and how do enzymes effect it?
There is no straight forward relation between enzyme and activation energy because although energy of reaction is fixed and is governed by laws of chemistry but for biochemical reactions concentration of enzyme and conc. of substrate affect rate of reaction and energy, but in general enzymes decrease activation energy of reaction.
How does activation energy affect chemical reactions?
The Arrhenius equation is: Ea = -RT ln(k/A) where Ea - activation energy R - universal gas constant ln - logarithm k - speed constant T - temperature in kelvins
Why activation energy is referred in the definition of enzymes?
The chemical term activation energy is the amount of energy required for a chemical reaction to take place. For more information about different chemical contact a scientists or science professor in one's area.
What is activation energy and how does it relate to cell metabolism?
Activation energy is the energy required to initiate a chemical reaction. In cell metabolism, enzymes lower the activation energy needed for reactions to occur, allowing them to proceed at a faster rate. This enables biological processes to efficiently convert molecules into products such as energy or building blocks for the cell.
What term is used to describe the minimum amount of energy required in order for a reaction to proceed?
This energy is called "energy of activation", it is used to overcame the energy barrier between reactants and products.
Which is a best definition of activation energy?
Activation energy is energy or power conducted that can be instantly activated for use when flick a light switch you used activation energy.
What it the term used to describe the energy needed to get a reaction started?
The energy needed to get a reaction started is called activation energy.
What energy is required for the reaction to occur?
Activation energy. The kinetic energy from collisions between particles is used to reach the transition state
What is it called when energy is required to start a chemical reaction?
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
What is the term used to describe energy needed to get a rection started?
ACTIVATION ENERGY IS THE ENERGY WHICH IS REQUIRED FOR INITIALIZING OF ANY TYPE OF REACTION.
What is the minimum amount of energy needed to start a chemical reaction?
The minimum amount of energy needed to start a chemical reaction is called the activation energy. It is the energy required to break the bonds in reactant molecules and initiate the reaction. Once this energy barrier is overcome, the reaction proceeds without additional energy input.
Explain the procedure used to determine the activation energy?
e
What describes the energy of activation?
Activation energy is the least amount of energy needed to start a chemical reaction. It is used to activate atoms or molecules in order for them to begin a chemical reaction.
What is the minimum energy required for molecules to react with each other called?
That is called the activation energy or energy of activation (Ea).
What is activation energy How does a catalyst affect activation energy?
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
What term describes energy that is required to get chemical reactions started?
Activation energy describes the energy that is required to get chemical reactions started.
