Why is it difficult for many chemical reactions in living things to occur without an enzyme?
A lot of chemical reaction only take place when a certain activation energy is reached. This is the kind of energy you need to start a reaction. In many cases this activation energy might mean that a chemical in our bodies would have to be above the temperature that would kill us just to take place!
A way around this problem is the enzyme, which can lower the activation energy by using something called an active site, which exists on the enzyme itself. Normally it takes energy to break bonds and split chemicals-up, or split molecules. This is where the enzyme comes in: the active site links with the molecule of the chemical you want to split, and it allows it to split-up.
Its worth noting that enzymes break-down above a certain temperature (we say they denature), which is why the body really works hard to keep your core temperature down.
What else can I help you with?
A catalyst for chemical reactions in biology systems is a?
A catalyst for chemical reactions in biological systems is typically an enzyme. Enzymes are protein molecules that speed up chemical reactions by lowering the activation energy required for the reaction to occur. They facilitate specific reactions without being consumed in the process.
What are the names of proteins that speed up chemical reactions?
Enzymes are proteins that speed up chemical reactions by lowering the activation energy needed for the reaction to occur.
What terms refers to a protein that catalyzes chemical reactions in organisms?
Yes, that is correct.
What is the common term for an organic catalyst?
The common term for an organic catalyst is an enzyme. Enzymes are biological molecules that increase the rate of chemical reactions without being consumed in the process.
How many different chemical reactions can a single enzyme catalyze?
1
Does enzyme contains high sugar?
No. An enzyme is a chemical that speeds up chemical reactions without adding any energy to them. Sugar is an energy source that makes some chemical reactions happen. They are different things and work on different principles.
What ia an enzyme?
an enzyme is protien that catalyzes chemical reactions for organisms
What is a protein that changes the rate of chemical reactions?
its called an enzyme
Does every enzyme possess an active site for catalyzing chemical reactions?
Yes, every enzyme possesses an active site where it catalyzes chemical reactions.
What kind of chemical reactions speed up enzyme catalysis?
This varies per enzyme and what it catalyzes but chemical reactions that result in an increase in temperature often speed up enzyme catalysis.

A catalyst for chemical reactions in biology systems is a?
A catalyst for chemical reactions in biological systems is typically an enzyme. Enzymes are protein molecules that speed up chemical reactions by lowering the activation energy required for the reaction to occur. They facilitate specific reactions without being consumed in the process.
What is the function of a simple enzyme in biological processes?
A simple enzyme functions as a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.
Proteins that speed up certain chemical reactions?
an enzyme
