What is the connection between enzymes and temperature?
enzymes and temperatures may cooperate to allow certain necessary reactions faster than it would be without enzymes. As the temperature rises, enzymes and substrates - the name of reactants in the enzymatic reaction - are more often collided, so the enzymes have a greater opportunity to catalyze reactions. This phenomenon increases until the optimum temperature is achieved. Further increase in temperature will denature enzymes and make them unnecessary for catalyzing reactions. At low temperature, there is not enough energy for the reactions that should take place, and enzymes are unable to do their work. For the reaction to take place, reactants must collide with sufficient energy to break the ties and create new ones. This is called the activation energy . Kinetic energy, the energy of the molecule as because of its movement can increase as temperature increases. This is one of the main reasons why there is a connection between enzymes and temperature.
When the temperature increases, enzymes and substrates collide and interact more and more. It means thatBy increasing the temperature, the enzymatic reaction occurs faster. In fact, an increase in the activity of enzymes and the increase in temperature is almost linear correlation. This phenomenon continues until the optimum temperature for the enzyme is achieved. At this temperature, the enzymatic reaction takes place as quickly as possible.
Most enzymes have an optimal temperature somewhere between 32 and 104 ° F (0 to 40 ° C). As the temperature rises above the optimum, the connections between enzymes and the temperature begin to denature - the bonds that hold the enzyme into the shape are beginning to break. When it happens, the activation sites that the substrates use no longer exist in the right shape and the substrates cannot be useful. It is possible for enzymes to survive higher than optimal temperatures, but this usually occurs if this higher temperature is exposed to for a short time.
The connection between enzymes and temperature also exists in terms of lower temperatures. At low temperatures nemThe substrates and enzymes are too kinetic energy. Even if it collides, there may not be enough energy to react. Thus, at a relatively low temperature, enzymes are unable to do their work. This is one of the reasons why the human body is trying to maintain at a certain temperature: too hot and proteins, including enzymes, denature; Too slowly, too cold and enzymatic reactions take place.
