Front

What is the role of enzymes in the body?

Back

Enzymes act as biological catalysts that speed up chemical reactions in the body.

Front

How do enzymes ensure efficient digestion?

Back

Enzymes ensure efficient digestion by fitting like a key into a lock, allowing them to catalyze specific reactions.

Front

What is the importance of enzymes in maintaining health?

Back

Enzymes are crucial for various biochemical processes, including digestion, metabolism, and DNA replication.

Front

What happens when enzymes are not present in a reaction?

Back

Without enzymes, reactions would occur too slowly to sustain life.

Front

How does temperature affect enzyme activity?

Back

Enzymes have an optimal temperature range; too high or too low temperatures can denature them and reduce their activity.

Front

What is the effect of pH on enzyme activity?

Back

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

Front

What is a substrate in the context of enzymes?

Back

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

Front

What is meant by 'enzyme specificity'?

Back

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

Front

What is the lock and key model of enzyme action?

Back

The lock and key model describes how the enzyme's active site (the lock) is specifically shaped to fit a particular substrate (the key).

Front

What is the role of enzymes in photosynthesis?

Back

Enzymes facilitate the chemical reactions that convert sunlight, water, and carbon dioxide into glucose and oxygen.
