How does enzymes speed up chemical reactions?
The way enzymes speed up chemical/biochemical reactions is the same way that catalysts work. They provide an alternate pathway for the reaction which has a LOWER activation energy. They don't actually decrease the activation energy of the pathway in question, but rather they provide a different pathway that has a lower energy of activation.
How does a catalyst increase the rate of a chemical reation?
A catalyst decreases the threshold energy value with which two particles must collide in order to react.
How does a catalyst speed up a reaction at low tempertures?
A catalysts speed up the rate of reaction by providing an alternate pathway which has a lower energy of activation than the normal pathway.
The addition of a increases the rate of reaction by providing an alternative pathway with a lower activation energy?
A catalyst, like enzymes.A catalyst is a substance that lowers the activation energy for a reaction and allows the process to speed up. The catalyst does not react with the substance so that it is 'used up'; in other words, it's reusable and comes out of the reaction unchanged.
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).

How enzymes works?
Provide an alternate pathway with a lower activation energy for a reaction
How does a catalyst increases the rate of a reaction?
By providing an alternative pathway with a lower activation energy.

Changing the course or pathway of a chemical reaction so that it requires less activation energy?
I have no clue, I need that answer also for Chemistry... :-/
How does an enyzme operate?
An enzyme works by providing an alternate pathway for the reaction, and one that has a LOWER activation energy than the original pathway without the enzyme. It thus speeds up the reaction.
What is the minimum amount of energy needed to start a chemical reaction?
activation energy ( I know it is right because it is in my science book)
What are the effects of enzymes on activation energy?
Enzymes are believed to act by altering the pathway of the reaction so that a LOWER activation energy is present. So, it doesn't actually change the Ea of the reaction, but rather provides a "different/separate" reaction path with a lower Ea.
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 energy pathway for phosphorescent light?
There is no energy pathway for it
What is a mechanism of nonspecific resistance?
activation of the complement via the alternative pathway
