Rennin is an enzyme that catalyzes a reaction that solidifies milk.  Rennin was added to there different test tubes with milk.  Each test tube was placed in a water bath for ten minutes.  The data collected during the experiment are shown.be

Test tube-1-Cold water bath-Few solids present in the liquid milk

Test tube-2-Room-temperature water bath-Semi-solid milk

Test tube-3-Hot water bath-No solids, only liquid milk

 Which statement best explains the result of test tube 3?

• The enzyme changed the product.

• The substrate was used up.

• The enzyme was denatured.

• The substrate reacted with the enzyme.

The function of an enzyme in a biochemical reaction is to –

• raise the temperature of the system

• speed up the rate of the reaction

• increase the amount of substrate added

• change the type of product formed

Which model best represents the molecules at the end of the reaction?

• A

• B

• C

• D

For an enzyme to be able to catalyze a reaction, the active site must -

• be occupied by an inhibitor

• increase the activation energy level

• have a complementary shape to the substrate

• cause the enzyme to be destroyed in the reaction

Enzymes are proteins that have a three-dimensional shape that is specific to a particular substrate. Environmental conditions can change the shape of the protein. What is the most likely result if the shape of the enzyme changes?

• The substrate will change its shape to match the enzyme.

• The enzyme will no longer be able to catalyze the reaction with the substrate.

• The products made from the enzyme and the substrate will be changed.

• The enzyme will be able to bind to more diverse substrates than before.

In which part of the plant cell does photosynthesis take place?

• Nucleus

• Mitochondria

• Chloroplast

• Ribosome
