Question

1 For each topic's table, fill in the specific reactant (substrate) and enzyme (HINT: enzymes are what kind of molecules?) for each tube, paying dlose attention to the procedures in the lab manual; they are not identical. U1 and U2 will have the same unknown reagent as the reactant, which may or may not react with the enzyme. Each tube's volume within a topic must be the same; therefore, water is added as a replacement (for what reagent?). Some of the tubes have additional reagents added prior to the incubation (excluding the dyes); indicate these reagents in the specific tubes in the miscellaneous column. Topic 1 Tube # Reactant? Enzyme? Miscellaneous Reagents? 81 82 B3 U1 Unknown U2 Unknown

Explanation / Answer

Enzymes are biological catalysts which alter the rate of a biological reaction by multiple-times. They are used to convert a specific type of reactant into a desired product under optimum biological conditions. Based upon the information, the table can be found as below:

Tube Reactant Enzyme Miscellaneous B1 Egg white Pepsin HCl B2 Egg white Pepsin NaOH B3 Egg white Pepsin Water U1 Unknown reagent Pepsin HCl U2 Unknown reagent Blank water
