7. Select the correct statements about enzymes: They are proteins D They reduce the rate of enzymatic reactions D They are specific D They are always simple proteins D They are capable to be regulated

The correct statements about enzymes are:<br /><br />1. They are proteins.<br />2. They are specific.<br />3. They are capable to be regulated.<br /><br />Explanation:<br />- Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.<br />- They are specific, meaning they can only catalyze a particular type of reaction or act on a specific substrate.<br />- Enzymes can be regulated, which means their activity can be controlled or modified to meet the needs of the organism.
