Enzymes

Front

What do enzymes speed up in chemical reactions?

Back

Enzymes speed up reaction rates by lowering the activation energy.

Front

What is the role of amylase in the body?

Back

Amylase is an enzyme that helps in the digestion of carbohydrates by breaking down starch into sugars.

Front

What is the term for the molecule upon which an enzyme acts?

Back

The molecule upon which an enzyme acts is called the substrate.

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 is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

How do enzymes affect activation energy?

Back

Enzymes lower the activation energy required for a reaction to occur.

Front

What is the significance of enzyme specificity?

Back

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

Front

What factors can affect enzyme activity?

Back

Factors that can affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is an enzyme inhibitor?

Back

An enzyme inhibitor is a substance that decreases the activity of an enzyme by binding to it.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different part of the enzyme.
