Enzymes Review

Front

What is the optimal pH range for pepsin activity?

Back

Pepsin functions optimally at a pH of around 1.5 to 2, which is acidic.

Front

At what pH does pepsin begin to denature?

Back

Pepsin begins to denature at pH values above 6.

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the specific reactant that an enzyme acts upon during a chemical reaction.

Front

What happens to trypsin's reactivity at pH 14?

Back

Trypsin shows no reactivity at pH 14, as it is denatured in such a highly alkaline environment.

Front

Define denaturation in relation to enzymes.

Back

Denaturation is the process by which an enzyme's structure is altered, rendering it inactive.

Front

What role do enzymes play in chemical reactions?

Back

Enzymes act as catalysts that regulate or speed up chemical reactions.

Front

What type of biomolecule are enzymes primarily classified as?

Back

Enzymes are primarily classified as proteins.

Front

How does temperature affect enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point, after which high temperatures can lead to denaturation.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity ensures that enzymes only catalyze specific reactions, which is crucial for metabolic regulation.

Front

What is the effect of extreme pH on enzyme structure?

Back

Extreme pH levels can lead to denaturation, altering the enzyme's structure and function.
