An enzyme, amylase, will affect the breakdown of carbohydrates, but it will not affect the breakdown of proteins. Which of the following can explain this kind of relation between enzyme and substrate?

Proteins are diverse in their structure and function, but carbohydrates are limited in shape and structure.

The substrate shape always has amino acids that interact with specific enzyme’s active site.

Enzymes are made of carbohydrate, so the active site can interact only with carbohydrates.

The enzyme active site has a specific sequence of amino acids that form a specific shape that interacts with specific molecules.

The diagram represents the energy levels that are involved in a biochemical reaction. Which statement about the effects of the enzyme on this reaction is correct?

The enzyme will decrease the activation energy and speed up the rate of the reaction.

The enzyme will not affect the activation, energy, or the rate of the reaction.

The enzyme will release the activation energy and slow down the rate of the reaction.

The enzyme will increase the activation energy and speed up the rate of the reaction.

The graphs below show the reaction rate for an enzyme across a range of temperatures and pH. Based on the graphs, this enzyme functions best at what temperature and pH?

Temperature of 36  ℃ and pH of 6

Temperature of 30  ℃ and pH of 8

Temperature of 36   ℃ and pH of 4

Temperature of 25  ℃ and pH of 4
