The Role of Enzymes in Biological Processes

What role do enzymes play in biological processes?

• They act as catalysts, speeding up reactions without being consumed.

• They are consumed in the reactions they catalyze.

• They slow down biochemical reactions.

• They are not specific to any substrate.

What happens to enzymes when they are exposed to extreme pH levels?

• They become denatured, altering their structure and rendering them inactive.

• They become more active and efficient.

• They change their substrate specificity.

• They remain unaffected.

Which model explains the specificity of enzyme-substrate interactions?

• Lock and key model

• Fluid mosaic model

• Induced fit model

• Central dogma model

What factors did Jocelyn and David focus on in their experiments regarding enzyme activity?

• Temperature and pH

• Substrate concentration and enzyme concentration

• Light and darkness

• Pressure and volume

What did Abraham explain about the role of enzymes in cellular environments?

• They are involved in processes such as digestion and energy production.

• They are responsible for transporting oxygen in the blood.

• They synthesize DNA and RNA.

• They are the main structural components of cell membranes.
