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 are enzymes composed of?

Back

Enzymes are composed of amino acids.

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 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 optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently, often around 30°C for many enzymes.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes lower the activation energy required for a reaction, allowing it to proceed faster.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, losing their shape and functionality.

Front

What is enzyme specificity?

Back

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

Front

What is a substrate?

Back

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

Front

What are products in an enzymatic reaction?

Back

Products are the molecules that result from the enzymatic reaction after the substrate has been transformed.
