Question

All enzymes are protein. Enzymes are able to catalyze chemical reactions over and over. Enzymes contain a cleft for substrate binding that is called the Substrate Site. One enzyme can bind to many different types of substrates. Enzymes are always localized to membranes; that is why mitochondria and chloroplasts contain so much inner membrane Any one enzyme will always operate at the same rate. Allosteric enzymes are enzymes that can be turned on and off. Inhibitors bind to enzymes and decrease their activity The products of enzymatic reactions sometimes act as enzyme inhibitorns. Enzyme names often end in "ase". All proteins are enzymes. Enzymes are only found in eukaryotic cells.

Explanation / Answer

ANSWER 1 - FALSE NOT ALL ENZYMES ARE PROTEINS AS SOME OF THEM ARE RIBOZYMES THAT ARE MADE UP OF RNA

ANSWER 2 TRUE ENZYMES ARE ABLE TO CATALYSE CHEMICAL REACTONS OVER AND OVER AGAIN .

ANSWER 3 FALSE ENZYME CONTAINS SUBSTRATE CLEFT WHICH ID CALLED ACTIVE SITE

ANSWER 4 TRUE There may be one or more substrates for each type of enzyme
