ENZYMES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Reading Passage:Enzymes are biological molecules (typically proteins) that significantly increase the rate of virtually all of the chemical reactions that take place within cells.They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.Some enzymes help break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are highly selective catalysts, meaning that each enzyme only increases the rate of a specific reaction. Question:Based on the reading, evaluate the statement as either True or False. Statement:Enzymes slow down chemical reactions.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.

Detailed explanation-2: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.

Detailed explanation-3: -An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell.

Detailed explanation-4: -Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.
