What is allosteric control in enzymes?

Back

Allosteric control refers to the regulation of an enzyme's activity through the binding of an effector molecule at a site other than the active site, leading to a change in the enzyme's conformation.

Front

What is a substrate in the context of enzymes?

Back

A substrate is any substance that is acted upon by an enzyme during a chemical reaction.

Front

What is a catalyst?

Back

A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.

Front

What happens to enzymes when they are heated to high temperatures?

Back

High temperatures can denature enzymes, altering their shape and rendering them inactive.

Front

What suffix do most enzymes end with?

Back

Most enzymes typically end with the suffix '-ase'.

Front

What is competitive inhibition?

Back

Competitive inhibition occurs when a substance competes with the substrate for binding to the active site of an enzyme.

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 denaturation in enzymes?

Back

Denaturation is the process by which an enzyme loses its functional shape due to external factors like heat or pH changes.

Front

What role do coenzymes play in enzymatic reactions?

Back

Coenzymes are organic molecules that assist enzymes in catalyzing reactions, often by acting as carriers for chemical groups.

Front

What is the induced fit model of enzyme action?

Back

The induced fit model suggests that the active site of an enzyme changes shape to better fit the substrate upon binding.
