10 Questions
What is the primary function of catalase in the antioxidant defense system?
To neutralize hydrogen peroxide (H₂O₂) by breaking it down into water and oxygen
What is the effect of extreme pH values on catalase activity?
It denatures the enzyme, affecting its activity
What is the relationship between temperature and catalase activity?
As temperature increases, catalase activity increases, but only up to a point
What is the role of cis-elements in the promoters of amylase genes?
To regulate plant development, maturation, and responses to environmental stresses
What is the optimal temperature range for catalase activity?
37°C to 40°C
What is the result of catalase denaturation at high temperatures?
A decrease in catalase activity
What is the role of regulatory elements in catalase gene expression?
To respond to specific signals and stressors
What is the effect of oxidative damage on cellular components?
It can damage proteins, lipids, and DNA
What is the significance of catalase in diseases associated with oxidative stress?
It plays a critical role in preventing oxidative damage
What is the product of catalase breaking down hydrogen peroxide?
Water (H₂O) and oxygen (O₂)
