What does enzyme do?
Answer:
enzymes are proteins that speed up reactions in biological processes (for example in your body) without getting used up in the reaction.
enzymes are protein catalysts
Enzyme is a protein that accelerates a chemical reaction.
breaks things down. lipase breaks down triglicerides and other fat molecules (fats), lactase breaks down lactose (dairy)... we have a lot of enzymes so that you can digest it and turn it into energy.
They are used to speed up chemical reactions
:)
Enzymes (named as such that they end in "-ase") break down and help build various proteins in an organism.
For instance, deoxyribonucleic acid helicase helps to "unzip" our DNA.
they lower the "energy of activation" making biological processes a lot easier (like 10 million times) without enzymes our bodies would fail... If you know cars then think of it as a coil pack... the battery cant put out that type of juice, so it relies on a differnt more efficient energy source (kind of the same thing... shruggs)
1) Enzyme is speices specific.
2) Enzyme provides reaction site to chemical reaction(s) for it's corresponding speices, which in turn enhance the rate(s) of reaction of the particular reaction(s).
3) In some cases, enzyme "A" may attach to the reaction site of enzyme "B", which in turn reduce the rate(s) of reaction of the particular reaction(s) that is/are corresponding to enzyme "B".
Enzymes are a type of protein that lower the activation energy for a reaction. Meaning they lower the amount of energy needed to start a reaction. They are never used up, they are not consumed instead reused. They are characterized by an activation site. The activation site varies by each protein. The activation site is like a lock which only a certain key can fit into. The key is the substrate, the substance which is converted in the reaction.
increases the rate of a reaction occurs but it does not increase its yield
A living system controls its activity through enzymes. An enzyme is a protein molecule that is a biological catalyst with three characteristics. First, the basic function of an enzyme is to increase the rate of a reaction. Most cellular reactions occur about a million times faster than they would in the absence of an enzyme. Second, most enzymes act specifically with only one reactant (called a substrate) to produce products. The third and most remarkable characteristic is that enzymes are regulated from a state of low activity to high activity and vice versa. Gradually, you will appreciate that the individuality of a living cell is due in large part to the unique set of some 3,000 enzymes that it is genetically programmed to produce. If even one enzyme is missing or defective, the results can be disastrous.
