9C Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

What is the role of enzymes in digestion?

Back

Enzymes help break down complex food molecules into simpler forms that can be easily absorbed by the body.

Front

What is substrate specificity in enzymes?

Back

Substrate specificity refers to the ability of an enzyme to choose exact substrate from a group of similar chemical molecules.

Front

What is the active site of an enzyme?

Back

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

Front

What factors affect enzyme activity?

Back

Enzyme activity can be affected by temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is denaturation of an enzyme?

Back

Denaturation is the process in which an enzyme loses its functional shape due to external stress, such as extreme temperature or pH, rendering it inactive.

Front

What is the significance of temperature for enzyme activity?

Back

Each enzyme has an optimal temperature range where it functions best; outside this range, activity decreases.

Front

What is the significance of pH for enzyme activity?

Back

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

Front

What is a coenzyme?

Back

A coenzyme is a non-protein organic molecule that assists enzymes in catalyzing reactions.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different part of the enzyme, changing its shape.
