Explain the inhibiting effect of sulfuric acid on the function of catalase Relate this to enzyme structure and chemistry?
Enzymes work best at the optimum pH of 7.0. The addition of sulfuric acid causes the pH to become lower and this deactivating the enzyme. This change in pH can cause the side chains of an amino acid to change in its charge which can result in a change of protein. This can greatly alter the reaction that was to take place.
What else can I help you with?
How does sulfuric acid stop the catalase reaction?
Sulfuric acid denatures the protein structure of catalase enzyme by disrupting its tertiary and quaternary structures through hydrogen bond disruption and charge interactions. This denaturation process alters the catalytic active site, leading to a loss of enzyme function and inhibition of catalase reaction.
What is the point of boiling a catalase?
Boiling catalase denatures the enzyme, meaning it disrupts its structure and renders it inactive. This can be useful in experiments to study the effects of temperature on enzyme activity or to deactivate the enzyme before further analysis.
Why does heat and acid cause a catalase to stop functioning?
Catalase is a protein and proteins can de-nature or change shapes when exposed to heat. Acid is very corrosive and so my guess would be that acid would just eat away at the protein and cause the protein to lose major parts needed to function
Do catalase reactions occer at 100 degrees?
No, catalase enzymes are denatured at high temperatures, such as 100 degrees Celsius. Denaturation causes the enzyme to lose its shape and function, which would prevent catalase reactions from occurring effectively at such high temperatures.
Why did Thomas A. Steitz win The Nobel Prize in Chemistry in 2009?
Thomas A. Steitz won the Nobel Prize in Chemistry in 2009 for his work on the structure and function of the ribosome, a fundamental component of protein synthesis in cells. His research provided valuable insights into the molecular mechanisms that drive protein production, leading to advances in drug development and understanding of genetic diseases.

What inhibits catalase?
Catalase can be inhibited by certain chemicals like cyanide, azide, and heavy metals, as well as by extreme pH levels. Competitive inhibitors that bind to the active site of catalase can also hinder its function.
Do catalase reactions occer at 100 degrees?
No, catalase enzymes are denatured at high temperatures, such as 100 degrees Celsius. Denaturation causes the enzyme to lose its shape and function, which would prevent catalase reactions from occurring effectively at such high temperatures.
How does temperature affect the function of catalase?
Temperature affects the speed of the reaction and how fast the catalase reacts. Higher temperatures cause faster reactions, lower temperatures cause slower reactions.
What is the relationship between structure and function?
Structure refers to the physical form or arrangement of components within a system, while function refers to the role or purpose that system performs. In biological systems, structure often determines function, as the way molecules are arranged impacts their ability to carry out specific tasks. Understanding the relationship between structure and function is crucial in fields such as biology, chemistry, and engineering to design optimized systems.
Why did Venkatraman Ramakrishnan win The Nobel Prize in Chemistry in 2009?
The Nobel Prize in Chemistry 2009 was awarded jointly to Venkatraman Ramakrishnan, Thomas A. Steitz and Ada E. Yonath for studies of the structure and function of the ribosome.
What would happen if water replace in catalase activity?
If water were to replace hydrogen peroxide in catalase activity, the catalase enzyme would not function as intended. Catalase specifically catalyzes the decomposition of hydrogen peroxide into water and oxygen, so substituting water would eliminate the substrate needed for the reaction. Consequently, the enzyme would be inactive, and the crucial protective role of catalase in breaking down harmful hydrogen peroxide would be compromised.
Why did Ada E. Yonath win The Nobel Prize in Chemistry in 2009?

What is the function of catylase?
Aparrently, this is a misnomer, and the correct spelling is catalase, an enzyme that breaks down peroxida into water and oxygen.
