Which of the following statements best helps explain how the enzyme speeds of the reaction?

Which of the following statements best helps explain how the enzyme speeds up the reaction? The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.

Which of the following statements best predicts the effect that a change from a moderately acidic?

Based on Figure 1, which of the following statements best predicts the effect that a change from a moderately acidic environment (pH near 6) to a basic environment will have on peroxidase activity? Peroxidase activity will decrease.

What is the reaction specificity of hexokinase?

Hexokinase catalyzes the conversion of glucose to glucose-6-phosphate but not the hydrolysis of ATP. Hexokinase's reaction specificity is explained by the compatibility of glucose and hexokinase's active site, which results in part from glucose's shape and charge.

Do enzymes get used up in a reaction?

Enzymes speed the reaction, or allow it to occur at lower energy levels and, once the reaction is complete, they are again available. In other words, they are not used up by the reaction and can be re-used. Enzymes are designed to work most effectively at a specific temperature and pH.
