Enzymes B1HN

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is competitive inhibition?

Back

A situation where a molecule competes with the substrate for binding to the active site of an enzyme.

Front

What is allosteric regulation?

Back

A process where an enzyme's activity is regulated by the binding of a molecule at a site other than the active site.

Front

What is denaturation in enzymes?

Back

The process where an enzyme loses its functional shape due to changes in temperature or pH.

Front

What is the optimum temperature for enzyme activity?

Back

The temperature at which an enzyme functions most efficiently, often around 37°C for many human enzymes.

Front

What factors can influence enzyme activity?

Back

Temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is an endergonic reaction?

Back

A chemical reaction that requires energy input to proceed, resulting in products with higher energy than the reactants.

Front

What is an exergonic reaction?

Back

A chemical reaction that releases energy, resulting in products with lower energy than the reactants.

Front

What is the role of substrate concentration in enzyme activity?

Back

Increasing substrate concentration generally increases the rate of reaction until the enzyme becomes saturated.
