Enzyme Activity and Plant Breeding

What role do enzymes play in cellular processes?

• They act as biological catalysts.

• They are structural components of cells.

• They are used for storing energy.

• They slow down chemical reactions.

Why is the study of enzymes important in biochemical laboratories?

• To increase the speed of all chemical reactions.

• To eliminate the need for enzymes in cells.

• To create new enzymes artificially.

• To understand their effects on chemical reactions.

What is the role of pyrophosphatases in plants?

• They help in photosynthesis.

• They aid in water absorption.

• They establish self-incompatibility.

• They promote seed germination.

What is required to measure the activity of pyrophosphatase?

• A pH meter.

• A temperature-controlled environment.

• A high-powered microscope.

• A color-changing substrate solution.

What does the substrate solution contain to indicate enzyme activity?

• Ammonium nitrate and sodium chloride.

• Ammonium mpate and ion sulfate.

• Calcium carbonate and magnesium sulfate.

• Potassium permanganate and iron sulfate.

How is the initial rate of reaction calculated?

• By measuring the temperature change.

• By constructing a standard curve from absorbance readings.

• By counting the number of bubbles produced.

• By observing the change in pH.

Why is it important to repeat the enzyme activity experiment multiple times?

• To increase the enzyme concentration.

• To change the substrate used.

• To reduce the cost of the experiment.

• To ensure the results are reliable.

What can studying pyrophosphate activity under different conditions reveal?

• The enzyme's function in vivo.

• The enzyme's resistance to heat.

• The enzyme's color change.

• The enzyme's ability to dissolve in water.

How can understanding self-incompatibility benefit plant breeding?

• By making plants more resistant to pests.

• By increasing the plant's height.

• By enabling more efficient breeding technologies.

• By reducing the need for fertilizers.

What is the ultimate goal of developing efficient plant breeding technologies?

• To create more colorful plants.

• To eliminate the need for sunlight.

• To feed Earth's growing population.

• To reduce the size of plants.
