Enzymes increase the amount of energy needed for a reaction to take place. True or False
False.
Enzymes act as catalysts and lower the amount of energy needed for a reaction to take place, thus increasing the rate of the reaction.
Most enzymes will have names that end in __ and most carbs will have names that end with __.
Most enzymes will have names that end in -ase, and most carbohydrates will have names that end with -ose.
False. Enzymes actually decrease the amount of energy needed for a reaction to take place. They act as catalysts, speeding up reactions by lowering the activation energy required.
False.
Enzymes actually decrease the amount of energy needed for a reaction to take place. They are catalysts that help speed up chemical reactions in living organisms.
To understand why enzymes decrease the energy needed for a reaction, we need to look at the concept of activation energy. Activation energy is the energy required to start a chemical reaction. In the absence of enzymes, this energy barrier can be quite high, making the reaction slow or even unfeasible.
Enzymes work by binding to reactant molecules, called substrates, and facilitating the conversion of substrates into products. They do this by creating an environment that brings the substrates closer together, orienting them in a way that promotes the reaction. Additionally, enzymes can provide an alternative reaction pathway with a lower activation energy.
By lowering the activation energy, enzymes increase the chances of reactant molecules colliding with the right orientation and sufficient energy to undergo the reaction. This leads to a higher reaction rate and faster overall reaction, without increasing the total energy required.
So, in summary, enzymes decrease the amount of energy needed for a reaction to take place, making them essential for numerous biological processes.
