Understanding Enzymes and Their Functions

Front

What is the induced fit model of enzyme action?

Back

The induced fit model suggests that enzymes change shape to fit the substrate upon binding, enhancing the enzyme's ability to catalyze the reaction.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to catalyze only specific reactions, ensuring that it interacts with particular substrates.

Front

How do enzymes help maintain homeostasis in the body?

Back

Enzymes contribute to homeostasis by breaking down harmful substances, thus regulating various biochemical processes.

Front

How does temperature affect enzyme activity?

Back

Enzyme activity increases with temperature up to a certain point, after which it decreases due to denaturation.

Front

What role do enzymes play in digestion?

Back

Enzymes break down food into absorbable molecules, facilitating nutrient absorption in the digestive system.

Front

Define enzymes.

Back

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

Front

What factors affect enzyme activity?

Back

Factors affecting enzyme activity include temperature, pH, substrate concentration, and enzyme concentration.

Front

What is the active site of an enzyme?

Back

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

Front

What is enzyme denaturation?

Back

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

Front

Explain the lock and key model of enzyme action.

Back

The lock and key model suggests that the enzyme's active site (the 'lock') is precisely shaped to fit a specific substrate (the 'key').
