Front

What is the relationship between enzymes and activation energy?

Back

chymotrypsin

Front

At 50 °C, how will enzymes in bacteria from hot springs be affected?

Back

The enzymes will not increase the rate of reactions as much as they would at 70 °C.

Front

The graph shows how the activity of an enzyme changes over a range of pH values. What conclusion can be drawn? Options: The optimum pH of the enzyme is 6.6., The optimum pH of the enzyme is 5.8, The enzyme’s activity continually increases as pH increases from 5.0 to 9.0, The enzyme’s activity is greater around pH of 8.0 than around pH of 5.0.

Back

The optimum pH of the enzyme is 6.6.

What is another name for the substance labeled "catalyst" in a biochemical process? Options: Enzyme, inorganic compound, Hormone, Antibody

Back

Enzyme

Front

Why are enzymes necessary for many cellular reactions?

Back

The reactions are too slow to meet the needs of the cell if enzymes are missing.

Front

What will most likely happen if an appropriate enzyme is added to a chemical reaction? Options: The reaction rate will increase, The equilibrium of the reaction will be maintained, The reaction rate will decrease, The reaction will stop.

Back

The reaction rate will increase.

Front

The human body maintains a temperature of around 98.6 degrees at all times. Enzymes are involved in almost every chemical reaction in the body. What is the connection between these two statements?

Back

Enzymes function best at a specific temperature.
