How does an enzymes interact with a substance?
Enzymes interact with substrates by binding only with specific substrates. Enzymes will then alter the shape of the substrate in order to induce reaction.
How do enzymes alter the rate of reaction?
Enzymes make biochemical reactions go much faster - the rate is a million to a billion times enhanced.
Do enzymes slow down or speed up a chemical reaction?
No, the sole purpose of enzymes are to increase the rate of a chemical reaction. Even if they are not at an optimal temperature, they will not slow down the reaction. They won't work as efficiently, but it will still be slightly faster than without the enzymes.
How does the presence of enzymes affect the equilibrium position of the breakdown of carbohydrate into glucose?
Enzymes cannot affect the equilibrium of a reaction, nor can they cause a thermodynamically unfavorable reaction to proceed. They are catalysts and can only alter the activation energy and therefore the rate of the reaction.
How do catalysts alter a reaction?
Catalysts does not alter the reaction at all but only speeds up the reaction. In an equilibrium reaction it speeds up the rate of reaction in both direction, forward and backward reactions. It actually absorbs the reactant particles into its surface and weakens their bonds. Reaction proceeds when the activation energy is overcomed. In the reactant side, particles collide with each other with high speed.
Are enzymes altered in the process of catalyzing chemical transformations?
they alter their shape in the process, but come unaltered at the end of the reaction (one of the main characteristics of catalysts)
How do enzymes alter the rate of biochemical reactions?
Enzymes make biochemical reactions go much faster - the rate is a million to a billion times enhanced.
What can alter the activation energy if a reaction?
A catalyst alter rate of reaction by lowering the activation
What is an enzyme and what does it do?
Enzymes are biological catalysts that alter the rate of reactions occurring in the cells. Enzymes are protein in nature. This means that high temperature or extreme pH can denature an enzyme and the damage is irreversible. Enzymes lower the activation energy of a reaction by providing an alternate path way that has lower activation energy.
Why are catalysts spread out in a reaction?
Catalysts are chemicals that alter the rate of a chemical reaction without being chemically changed themselves . However to alter the rate of the reaction , the catalysts need to come in contact with the reactant particles. Spreading out the catalyst increases its surface area , hence increases the chances of coming in contact with the reactant particles . So they are able to provide the reactant particles an alternative route with a lower activation energy for the reactant particles to collide and form the product .
What would you change to alter enzymes?
change many things
What do prokaryotes do in response to a chemical signal?
alter the level of production of various enzymes
