Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following best explains why enzymes are necessary for reactions in our cells?
A
The reactions are too slow to meet the needs of the cell if enzymes are missing.
B
Enzymes supply the oxygen necessary for the reactions.
C
Enzymes change reactants from solid to liquid during the reactions.
D
The reactions take up too much space in the cell if enzymes are missing.
Explanation: 

Detailed explanation-1: -Answer: D-The reactions are too slow to meet the needs of the cell if enzymes are missing. Most commonly, enzymes accelerate biochemical reactions by lowering the amount of activation energy required.

Detailed explanation-2: -They speed up biochemical reactions. Under the conditions inside living cells, biochemical reactions would occur too slowly to support life without the help of enzymes. Enzymes increase the rate of biochemical reactions by reducing the amount of activation energy needed for reactants to start reacting.

Detailed explanation-3: -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.

Detailed explanation-4: -Which of the following best describes the action of an enzyme? Explanation: Enzymes are biological molecules that help catalyze reactions by lowering the energy of activation and increasing the rate of a reaction.

Detailed explanation-5: -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.
