Enzyme Activity and Lactose Breakdown in Virtual Lab

The video tutorial guides students through a virtual enzyme lab on Google Classroom, focusing on lactase's role in breaking down lactose. It covers data collection, graph creation, and analysis using Google Sheets, emphasizing the effects of pH and substrate concentration on enzyme activity. Students are instructed on customizing graphs and linking them to data, with a focus on interpreting results and understanding enzyme reactions.

What is the primary enzyme being studied in the virtual lab?

• Lipase

• Lactase

• Amylase

• Protease

What reaction does lactase facilitate in the lab?

• Condensation

• Oxidation

• Hydrolysis

• Reduction

What is the effect of pH on enzyme activity as observed in the lab?

• pH 3 shows the highest activity

• pH 9 shows the highest activity

• pH 5 shows the highest activity

• pH 7 shows the highest activity

What is the dependent variable in the enzyme lab graph?

• pH level

• Amount of substrate

• Temperature

• Number of molecules formed-per-minute

What is the effect of substrate concentration on enzyme activity?

• Lower concentration increases activity

• Concentration has no effect

• Higher concentration increases activity

• Higher concentration decreases activity

What should be included on the horizontal axis of the graph?

• Amount of substrate in grams

• Temperature in Celsius

• Time in minutes

• Number of molecules formed-per-minute

What is the purpose of adding labels to the graph?

• To make it colorful

• To make it easier to interpret

• To change the graph type

• To increase the size

What should be the title of the graph showing the effect of lactose amount?

• Effect of Temperature on Enzyme Activity

• Effect of Amount of Lactose on Number of Molecules Formed-per-Minute

• Effect of pH on Enzyme Activity

• Effect of Time on Enzyme Activity

What happens if you link the graph to the Google Sheet?

• The graph disappears

• The graph changes color

• The graph updates with data changes

• The graph becomes static

What is the final step after creating and labeling the graph?

• Delete the graph

• Print the graph

• Copy and paste it into the lab write-up

• Change the graph type
