AP Bio Enzymes

Front

What is the optimal temperature range for enzyme activity?

Back

Enzymes function best at a specific temperature, typically around 37 degrees Celsius (98.6 degrees Fahrenheit) for human enzymes.

Front

What is a catalyst?

Back

A substance that speeds up a chemical reaction without being consumed in the process.

Front

What suffix do most enzymes have?

Back

-ase

Front

What happens to enzymes at high temperatures?

Back

The shapes of the enzymes are altered, a process known as denaturation.

Front

What is allosteric control in enzymes?

Back

Allosteric control refers to the regulation of an enzyme's activity through the binding of an activator or inhibitor at a site other than the active site.

Front

What is the active site of an enzyme?

Back

The specific region of an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is denaturation?

Back

Denaturation is the process in which proteins lose their structure and function due to external stress, such as heat or pH changes.

Front

What is competitive inhibition?

Back

A type of enzyme inhibition where a substance competes with the substrate for binding to the active site.

Front

What role do enzymes play in biological reactions?

Back

Enzymes act as catalysts to accelerate chemical reactions in biological systems.

Front

How does pH affect enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to decreased activity or denaturation.
