Science 40

Question 1:

Based on the information in the passage and the information in Figure 1, it can be inferred that the energy of the products of a reaction is:

Question 2:

A student increases the concentration of enzyme and the rate of the reaction increases. He then further increases the concentration of enzyme, and the reaction remains the same. The most probable explanation for this is:

Question 3:

Based on Figure 1, the activation energy required in a reaction without the help of a catalyst relates how to the activation energy in a reaction with a catalyst? The activation energy in a reaction without a catalyst is approximately:

Question 4:

A substrate is the compound with which an enzyme interacts to catalyze a reaction. A student was measuring the effects of increasing substrate concentration on a reaction. Based on the passage, it can be inferred that increasing the substrate concentration will:

Question 5:

Based on the figure, as a reaction proceeds, the energy in the reaction:
