Catalysts and Inhibitors in Reactions

The video explains the difference between catalysts and inhibitors in chemical reactions. Catalysts speed up reactions without being consumed, sometimes lowering the energy required or changing the reaction path. Enzymes in the human body act as catalysts, aiding in digestion. Inhibitors, on the other hand, slow down or stop reactions without being consumed. Some enzymes and poisons act as inhibitors. The video concludes with a reminder of the importance of kindness.

What is required for a chemical reaction to occur?

• A catalyst

• A certain amount of energy

• An inhibitor

• A specific temperature

How do catalysts affect chemical reactions?

• They stop the reaction

• They speed up the reaction

• They slow down the reaction

• They increase the amount of product

Which of the following is an example of a catalyst in the human body?

• Lipase in the pancreas

• None of the above

• Amylase in saliva

• Both amylase and lipase

What is the role of digestive enzymes in the human body?

• To build proteins

• To store energy

• To break down food

• To transport nutrients

What is the primary function of an inhibitor in a chemical reaction?

• To increase the energy required

• To slow down or stop the reaction

• To change the amount of product

• To speed up the reaction

Which of the following can act as enzyme inhibitors in nature?

• Water

• Animal or plant poisons

• Oxygen

• Carbon dioxide

How do inhibitors differ from catalysts in their function?

• Inhibitors have no effect on reactions

• Inhibitors change the amount of product

• Inhibitors decrease the reaction rate

• Inhibitors increase the reaction rate

Do catalysts and inhibitors change the amount of product in a reaction?

• Yes, they increase the product

• Yes, they decrease the product

• No, they only change the rate of reaction

• No, they have no effect on the reaction
