Reading Passage:Enzymes are proteins that do the everyday work within a cell. Their basic function is to speed up the process and efficiency of a reaction without themselves being consumed in the process. Enzymes are responsible for moving large parts of a cell’s internal structure, such as pulling chromosomes apart when a cell divides. Enzymes make the energy molecules that are constantly needed for the cell to survive. And they break down molecules, recycle the old parts and make new molecules that allow the cell to grow.Question:Enzymes affect the reactions in living cells by changing the

A	speed of the reaction.
B	products of the reaction.
C	pH of the reaction.
D	temperature of the reaction.

Explanation:

Detailed explanation-1: -What Do Enzymes Do? Enzymes are protein catalysts that speed biochemical reactions by facilitating the molecular rearrangements that support cell function. Recall that chemical reactions convert substrates into products, often by attaching chemical groups to or breaking off chemical groups from the substrates.

Detailed explanation-2: -Enzymes include detoxification, muscle building, and breaking down food particles during digestion. Enzymes actually accelerate the rate of a chemical reaction to support life. Enzymes are very helpful in performing important functions of our body.

Detailed explanation-3: -The correct answer: The statement that is false about the enzymes d. A specific enzyme can catalyze a variety of chemical reactions. The enzymes are basically proteins that are produced from the secretory cells.

Detailed explanation-4: -This statement about enzymes is true: Enzymes accelerate reactions by lowering the activation energy. Enzymes are proteins whose three-dimensional form is key to their function. Enzymes do not alter the overall change in free energy for a reaction.
