An enzyme is a catalyst for chemical reactions. Three variables that can cause an enzyme to lose its ability to function are temperature, pH level and concentration.
Molecules that act as catalysts in biological systems are enzymes. Enzyme catalyze chemical reactions by lowering the activation energy.
As a co-enzyme- in many functions- Fighting coldsmostly.
Enzymes lower the amount of Activation Energy needed for a chemical reaction, therefore speeding up the chemical reaction. For an enzyme to do this it needs to be at the correct pH, salinity, and temperature otherwise the enzyme will not be able to work. When an enzyme is in a pH that is not suitable, the enzyme's shape and structure alter and make it unable to speed up a reaction.
enzyme
Enzymes are biological catalysts so Amylase, Maltase, Protease, Lipase. Yeast is also a biological catalyst.
biological molecule
An enzyme is the biological equivalent of a catalyst.
An enzyme has only one substrate that it works with so it has only one function. This is called a lock and key mechanism. Other things can affect the enzyme such as temperature, pH level and levels of either the substrate or the products. High temperature can denature the enzyme (they are proteins). They can not fit the lock (substrate).
Yes, that is exactly what an enzyme is.
DNA helicase. This is the enzyme that "unzips" DNA.

A biological catalyst is an enzyme. An enzyme lowers the amount of activiation energy in order for a reaction to occur, they are also reusable.
A biological catalyst is an enzyme, enzyme are found all over living things, each with specific use
