How do enzymes, a type of protein, facilitate biochemical reactions?

• By providing energy to the reaction

• By lowering the activation energy required

• By increasing the temperature of the reaction

• By changing the pH of the environment

Compare and contrast the roles of DNA and RNA in cells.

• DNA stores genetic information, while RNA translates it into proteins.

• DNA and RNA both store genetic information but in different cells.

• DNA is involved in energy transfer, while RNA stores genetic information.

• DNA and RNA both catalyze biochemical reactions.

Design an experiment to test the effect of temperature on enzyme activity.

• Measure enzyme activity at different temperatures and compare the results.

• Measure enzyme activity at a single temperature.

• Measure enzyme activity without changing any conditions.

• Measure enzyme activity only at room temperature.
