Answer:
Different things make different vibrations when they hit, and that's why you hear high notes and low notes. Things that vibrate quickly make small waves in the air, and that sounds to you like a high-pitched note. Things that vibrate slowly make longer waves in the air, that sound to you like a low-pitched note.
 
        
                    
             
        
        
        
Answer: If you have an excess of enzyme but not enough substrate, the reaction will be limited by the substrate availability. 
Explanation: Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product.

Answer:
The two major pancreatic enzymes that digest proteins in the small intestine are chymotrypsin and trypsin. Trypsin activates other protein-digesting enzymes called proteases, and together, these enzymes break proteins down to tripeptides, dipeptides, and individual amino acids.
