No, enzymes are considered catalysts in a reaction. This means that they help a reaction occur that may not otherwise. By definition catalysts (and therefore enzymes) are NOT used up during a reaction. They assist the reactants and then are regenerated to be used again (whereas the reactants become new products are are consumed). They do this by lowering the activation energy (the energy needed to cause the reaction). They lower the activation energy by a variety of ways, usually by getting the involved reactants into a close proximity, and by causing a physical or chemical change to them, allowing the reaction to proceed.

In our bodies enzymes are essential as the body has a very specific environment (temperature, pH range, etc) that make several of our vital reaction impossibly slow without them to help us along. Without them, the reactions that must occur millions of times each second in our bodies could take weeks, months, or years to happen otherwise. At that scale, our life would be impossible.

Are enzymes affected by the chemical reaction they speed up?

Enzymes are biological catalysts. A catalyst speeds up a reaction by lowering the activation energy required. In other words a catalyst offers an alternative pathway to increase the rate of reaction- it is not consumed during a reaction, or affected.


Do enzymes speed up the rate of chemical reations without being affected themselves by reaction?

Yes


Substances that promote chemical reactions in living things but not affected by the reaction are?

enzymes. Enzymes are biological catalysts that increase the rate of chemical reactions in living organisms without being consumed in the process. They help lower the activation energy required for a reaction to occur.

What are enzymes called because they affect the speed of chemical reaction without being consumed?

enzymes are never consumed in a chemical reaction, therefore the answer to your question is that enzymes that affect the speed of a chemical reaction without being consumed are indeed called enzymes.


How are enzymes represented in a chemical equation?

Enzymes are catalysts and increase the speed of a chemical reaction without themselves .A chemical reaction can be represented by a chemical equation. An enzyme is a protein that speeds up a biochemical reaction .


What are characteristics of enzymes?

Enzymes are proteins that act as biological catalysts, speeding up chemical reactions. They are highly specific, meaning they only catalyze one type of reaction. Enzymes can be affected by factors such as temperature and pH, which can impact their function.
