What would happen to an enzymes facilitated reaction if temperature were increased?
Increasing the temperature generally increases the rate of an enzyme-facilitated reaction up to an optimal point, as it enhances molecular movement and substrate collisions. However, if the temperature exceeds the enzyme's optimal range, the enzyme may denature, losing its three-dimensional structure and, consequently, its activity. This denaturation leads to a significant decrease or complete loss of the reaction rate. Therefore, while moderate temperature increases can enhance reaction rates, excessive heat can be detrimental to enzyme function.

What is the speed of a chemical reaction is increased by?
Most effectively increased speed by temperature increase and adding a catalyst ( = enzymes in biological reactions. Further measures: raising concentration of reactants, grinding solids, mixing, for some reactions: put in light scource
Would a higher enzymes concentration make the reaction faster or slower?
Increased enzymes would increase the rate of the reaction up to a certain point. They would reach a point where there are no more reactions to help out.
An increase in the temperature result in increased function of enzymes in a chemical reaction because heat makes the substrate molecule move more rapidly thus coming into contact with enzymes true?
The statement in question is partially true. It is right to think that an increase in reaction temperature will result in an increase in the rate of the reaction since the interacting molecules will have more kinetic energy. However, it is important to remember that enzymes are after all proteinacious structures. They have an optimum temperature at which they function best. The reaction conditions must be optimized to hold the reaction steadily at this optimum temperature. If the temperature is too high, the enzyme denatures (degrades due to excess heating) you suck lol
What changes of temperature on rate of reaction?
The rate of reaction increases with increasing temperature. When the temperature is increased, the kinetic energy of the reacting particles hence the frequency of effective collisions are also increased. Hence the rate of reaction is faster.
When the temperature was set at 0o the reaction rate for enzymes?
At 0°C, the reaction rate for enzymes is significantly slowed down. This is because low temperatures reduce molecular movement, leading to fewer collisions between enzymes and substrates. While enzymes remain intact at this temperature, their activity is greatly diminished, often resulting in very low or negligible reaction rates. Optimal enzyme activity typically occurs at higher temperatures, where molecular motion increases.
What happen most likely happen to the rate of reaction of a human enzyme when the temperature is increased gradually from 40c to 90c?
When a high enough temperature is reached enzymes denature (unfold) and loose all their functions. Most human enzymes have an optimal temperature of 40C. As you increase from 40C to 90C the reaction rate will decrease until it reaches 0.

Does cold water kill enzymes?
No low temperture only stops the function of an enzyme.When temperature increased enzymes become active

What factors may influence the speed at which enzymes function?
Temperature is definitely one. USUALLY, the higher the temperature, the faster the reaction.
Do enzymes increase the activation energy of biochemical reactions?
Enzymes speed up a chemical reaction by lowering the energy required for a reaction to procede, the Activation Energy (Ea). The overall change in energy of the reaction is unchanged, so the net amount of energy released in a reaction is not increased.
How does temperature affect catalase activity?
Increased temp give increased reaction rate. Only an approximation, but 10 degrees is said to double the rate.
When an enzyme binds with its substrate the activation energy needed for the chemical reaction to occur is increased True or False?
False. When an enzyme binds with its substrate, the activation energy needed for the chemical reaction is decreased, not increased. This reduction in activation energy allows the reaction to occur more quickly and at lower temperatures, making it easier for the reaction to proceed.
How do enzymes affect activation energy and reaction temperature?
As kinetic energy, and therefore temperature increases, the number of effective collisions which result in sufficient activation energy also increases, which is why reactions happen at a faster rate at higher temperatures.
What changes of temperature on rate of reaction?
The rate of reaction increases with increasing temperature. When the temperature is increased, the kinetic energy of the reacting particles hence the frequency of effective collisions are also increased. Hence the rate of reaction is faster.
