Pre AP Bio Review - Unit 3 Flashcard 1

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature for enzyme activity is the temperature at which the enzyme functions best, often around 30°C for many enzymes.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where the shape of an enzyme is altered due to high temperature or extreme pH, rendering it inactive.

Front

What is the role of pH in enzyme activity?

Back

pH affects the shape and charge of the enzyme and substrate, influencing the enzyme's activity. Each enzyme has an optimal pH range.

Front

What are enzymes made of?

Back

Enzymes are made of proteins, which are composed of amino acids.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, losing their functional shape and activity.

Front

What is the relationship between enzyme concentration and reaction rate?

Back

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

Front

What is the effect of substrate concentration on enzyme activity?

Back

Increasing substrate concentration increases the reaction rate until the enzyme becomes saturated.

Front

What is an active site?

Back

The active site is the specific region on an enzyme where the substrate binds and the reaction occurs.

Front

What is the function of enzymes in biological reactions?

Back

Enzymes act as catalysts, speeding up chemical reactions without being consumed in the process.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity means that each enzyme only catalyzes a specific reaction or type of reaction, ensuring proper metabolic processes.
