What is the first step in the warmup activity related to osmosis?

• Draw a graph of sucrose molarity

• Identify the equilibrium point

• Determine the molar concentration of the cell

• Calculate the water potential

What is the role of the active site in an enzyme?

• To produce ATP

• To transport molecules across the cell membrane

• To interact specifically with substrate molecules

• To store energy

How do enzymes speed up chemical reactions?

• By increasing the temperature

• By lowering the activation energy

• By increasing the substrate concentration

• By changing the pH

What happens to an enzyme if it undergoes denaturation?

• Its structure is disrupted, eliminating its ability to catalyze reactions

• It becomes more efficient

• It binds more substrates

• It speeds up the reaction

Which environmental factors can cause changes to an enzyme's structure?

• Salinity and oxygen levels

• Pressure and humidity

• Light and sound

• Temperature and pH

What is competitive inhibition in enzyme activity?

• When the substrate concentration is too high

• When the enzyme is denatured

• When an inhibitor binds to the active site, blocking the substrate

• When an inhibitor binds to an allosteric site

What is the optimal pH for turnip peroxidase activity based on the student's graph?

• pH 10

• pH 3

• pH 5

• pH 7

What is the purpose of graphing data in enzyme experiments?

• To visualize the relationship between variables

• To make the experiment look more professional

• To avoid doing calculations

• To confuse the students

Why is it important to understand the rate of enzyme reactions?

• All of the above

• To design better experiments

• To determine the enzyme's efficiency

• To predict the outcome of chemical reactions
