The are catalysts. They make it a LOT easier and more likely for some otherwise pretty improbably reactions to occur. Like all catalysts they aren't consumed by reactions they catalyse. But also present in the cells are many proteases. They breakdown proteins, including enzymes, and recycle the ingredients used to make them. And enzymes are continuously being produced, the amounts of which depend on what genes are expressed at the moment, all controlled by hundreds of hormones and other chemical signals with in and from outside the cell. So in this way the function of the cell can change in response to external cues and internal conditions.
Enzymes catalyze chemical reactions within the cell by acting as substrates and forming new products.
enzymes help reduce the requirement for reactions to take place within the cell. have a look http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/E/Enzymes.html enzymes help reduce the requirement for reactions to take place within the cell. have a look http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/E/Enzymes.html
A hormone called thyroxine. The thyroid gland is attached to the windpipe. It makes a hormone called thyroxine.THYROXINE IS THE HORMONE THAT CONTROLS CHEMICAL REACTIONS IN CELLS.
Enzymes speed up chemical reactions in a cell. without enzymes, many chemical reactions that are neccassarry for life would either take to long or not occur at all.
These chemicals are called enzymes.
i think it's enzymes
Enzymes speed up reactions that help sustain life.

I guess that the correct answer to that is enzymes. Enzymes, on the other hand, are proteins. Therefore, this is also one of the functions that proteins have.

enzymes
They help bring about chemical reactions.
The enzymes in the cell act as catalysts for chemical reactions. They lower the activation energy of these reactions in order to speed up the reaction rate.
