Biological Detergents

The video explains how catalysts speed up reactions without being consumed, using a bicycle analogy. Enzymes are specific to substrates and are named with the suffix 'ase'. Biological detergents contain enzymes like proteases and lipases that break down stains. Cellulase is not used in detergents as it can damage cotton clothing, but amylases are safe for starches. Biological detergents are energy efficient, environmentally friendly, and biodegradable, allowing laundry to be done in warm water, preserving clothing and colors.

What role does a catalyst play in a chemical reaction?

• It speeds up the reaction without being consumed.

• It slows down the reaction.

• It changes the products of the reaction.

• It is consumed in the reaction.

Which part of an enzyme is responsible for its catalytic activity?

• The enzyme's prefix

• The entire enzyme structure

• The active site

• The enzyme's suffix

What is the function of cellulase?

• Breaks down lipids

• Breaks down proteins

• Breaks down cellulose into sugars

• Breaks down starches

Why are cellulases not typically added to biological detergents?

• They could damage cotton clothing.

• They do not work at low temperatures.

• They are too expensive.

• They are not effective in removing stains.

What is one advantage of using biological detergents over traditional cleaning agents?

• They are harmful to the environment.

• They are not biodegradable.

• They require boiling water to be effective.

• They can be used in warm water, saving energy.
