Question

For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase should be used only once. Any substance that will bind to a protein is known as its ________________. Enzymes bind their __________________ at the __________________. The enzyme hexokinase is so specific that it reacts with only one of the two __________________ of glucose. Enzymes catalyze a chemical reaction by lowering the __________________, because they provide conditions favorable for the formation of a __________________ intermediate called the __________________. Once the reaction is completed, the enzyme releases the __________________ of the reaction.

Answer 1

An enzyme's binding substance is known as its substrate. Enzymes bind their substrates at the active site of the enzyme. Enzymes lower the activation energy of a chemical reaction by providing conditions favorable for the formation of a transition state intermediate called the substrate-enzyme complex.

An enzyme's binding substance is known as its substrate. Enzymes bind their substrates at the active site of the enzyme. The enzyme hexokinase is so specific that it reacts with only one of the two isomers of glucose. Enzymes lower the activation energy of a chemical reaction by providing conditions favorable for the formation of a transition state intermediate called the substrate-enzyme complex. Once the reaction is completed, the enzyme releases the products of the reaction.
