Biology Test - Enzymes and Catalysts

What is an active site and what is its job?

An active site is where the enzymes substrates undergo a chemical reaction.

What is the general purpose of enzymes in the human body?

Speeds up reactions in the body

What is the relationship between a substrate and a product?

Substrate goes in and goes through a chemical reaction and produces a product.

What environmental factors can affect the way enzymes work? E

Temp - Changes shape of enzyme. pH - Proteins denature when acid is low. Inhabitors - Stop or slow down the active site.

Why do enzymes generally only bind to one type of substrate?

They can only bind to certain substrates.

What is denaturing and what cause it to occur?

Denaturing is the loss of the normal shape of a protein.

What are some enzymes and their purpose?

Digestive enzymes - Enzymes that break down food.

What is the difference between a catalyst and enzyme?

Enzymes are a type of catalyst found in only living things and Catalysts speed up a reaction.

Explain how an enzyme works using terms from 1-3

Enzymes are a type of catalyst, catalysts speed up a reaction and substrates join together to make an active site and create a product.
