AP Enzymes

Front

What is competitive inhibition?

Back

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

Front

What happens to enzymes at high temperatures?

Back

The shapes of the enzyme are altered or denatured, affecting their functionality.

Front

What does specificity mean in the context of enzymes?

Back

Each enzyme only has one substrate that will fit its active site.

Front

What is allosteric activation?

Back

A process where a molecule binds to an enzyme at a site other than the active site, increasing the enzyme's affinity for its substrate.

Front

What is the role of alarmone in E. Coli?

Back

Alarmone binds to the enzyme RelA, enhancing its ability to catalyze the formation of specific molecules.

Front

What is non-competitive inhibition?

Back

A type of enzyme inhibition where an inhibitor binds to an enzyme at a site other than the active site, reducing the enzyme's activity regardless of substrate concentration.

Front

What is feedback inhibition?

Back

A regulatory mechanism where the end product of a metabolic pathway inhibits an enzyme involved in its synthesis.

Front

What is the active site of an enzyme?

Back

The specific region of an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon during a chemical reaction.

Front

What is denaturation in enzymes?

Back

The process where an enzyme loses its three-dimensional structure, rendering it inactive.
