Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms.

Front

What is the primary function of an enzyme?

Back

The primary function of an enzyme is to speed up reactions by lowering the activation energy required.

Front

What is an active site?

Back

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

Front

What is a substrate?

Back

A substrate is the reactant molecule that an enzyme acts upon.

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 the optimum pH for an enzyme?

Back

The optimum pH is the pH at which an enzyme exhibits maximum activity.

Front

What happens to enzymes at extreme temperatures?

Back

Extreme temperatures can denature enzymes, altering their structure and rendering them inactive.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, such as extreme pH or temperature.

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 role of coenzymes?

Back

Coenzymes are organic molecules that assist enzymes in catalyzing reactions.
