Enzymes and pH Review

Front

What is the primary function of enzymes in biological systems?

Back

Enzymes speed up chemical reactions.

Front

What type of macromolecule are enzymes classified as?

Back

Enzymes are classified as proteins.

Front

What term describes enzymes due to their role in facilitating reactions?

Back

Enzymes are known as biological catalysts.

Front

What effect do changes in pH have on enzyme structure?

Back

Changes in pH can denature an enzyme, altering its shape and function.

Front

What is denaturation in the context of enzymes?

Back

Denaturation refers to the process where an enzyme loses its shape and, consequently, its function.

Front

How does temperature affect enzyme activity?

Back

Extreme temperatures can denature enzymes, slowing down or stopping chemical reactions.

Front

What happens to enzyme activity during hypothermia?

Back

Enzyme activity decreases as enzymes may denature, leading to slowed chemical reactions.

Front

What is the optimal pH range for most enzymes?

Back

Most enzymes have an optimal pH range around neutral (pH 7), but some function best in acidic or basic conditions.

Front

What is the relationship between enzyme concentration and reaction rate?

Back

Increasing enzyme concentration generally increases the reaction rate, provided substrate is available.

Front

What is substrate specificity in enzymes?

Back

Substrate specificity refers to the ability of an enzyme to select and catalyze a specific substrate.
