|
|
Enzymes are biological catalysts.
|
|
|
Enzymes are essential to many of the processes in our body.
|
|
|
Enzymes can only break down larger molecules into smaller ones.
|
|
|
Enzymes are specific to the substrates they react with.
|
|
|
Enzymes are not used up after catalyzing a reaction.

Detailed explanation-1: -An enzyme provides an alternate pathway having lower activation energy. The statement (C) is false with respect to an enzyme’s ability to catalyses a reaction.
Detailed explanation-2: -Enzymes provide support for many important processes within the body. Some examples include: The digestive system: Enzymes help the body break down larger complex molecules into smaller molecules, such as glucose, so that the body can use them as fuel.
Detailed explanation-3: -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 speeds up a specific reaction.
Detailed explanation-4: -Answer and Explanation: The breakdown of large molecules by enzymes, through the addition of water is called a hydrolysis reaction. This type of reaction breaks down large polymers (such as proteins) into smaller fragments through breaking of the bonds. Energy release also accompanies this type of reaction.
