EOC Review: Enzymes

In a reaction, the ______________ binds to the __________________ of the enzyme

• substrate, active site

• active site, substrate

• enzyme, active site

• products, active site

Enzyme specificity means...

• each enzyme only works on one substrate

• each enzyme has a specific shape

• each enzyme has a specific location

• each enzyme is a specific protein

Enzymes are...

• proteins

• lipids

• nucleic acids

• carbohydrates

What is the optimum pH of trypsin?

• 4

• 6

• 8

• 10

Which line represents the rate of a reaction with an enzyme present?

• red line

• blue line

What does it mean for an enzyme to denature?

• the shape of the active site of the enzyme changes, making it unable to bond with the substrate

• the enzyme starts to react with a different substrate

• the enzyme melts and falls apart

• the enzyme moves to a different location so it can be in its ideal temperature or pH

Where would you expect to find an enzyme like pepsin?

• in an acidic environment like the stomach

• in a basic environment like the small intestine

• in a neutral environment

Breaking down of a large molecule into two or more products

• catabolism

• anabolism

Forming a larger molecule from two or more smaller molecules

• catabolism

• anabolism

What is the role of enzymes?

• to reduce the amount of activation energy required in a reaction

• to break down large molecules

• to help with digestion of food

• to increase the amount of energy available for a reaction
