Enzymes: Biological Catalysts

What are enzymes primarily composed of?

• Carbohydrates

• Nucleic acids

• Lipids

• Proteins

Which model explains the specificity of enzyme-substrate interaction?

• Fluid mosaic model

• Induced fit model

• Lock and key model

• Bohr model

What happens when an enzyme's active site is altered due to temperature or pH changes?

• The enzyme becomes more efficient

• The enzyme becomes denatured

• The enzyme speeds up the reaction

• The enzyme changes its substrate

Which enzyme is responsible for breaking down hydrogen peroxide into water and oxygen?

• Amylase

• Lipase

• Protease

• Catalase

What role do builder enzymes play in biochemical reactions?

• They break down large molecules

• They join smaller molecules to form larger ones

• They change the pH of the reaction

• They denature other enzymes
