Enzymes 1

Front

What is the active site of an enzyme?

Back

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

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 type of macromolecule are enzymes?

Back

Enzymes are proteins that act as biological catalysts.

Front

What does the Lock & Key Model describe?

Back

The Lock & Key Model describes how a substrate fits into the active site of an enzyme like a key fits into a lock.

Front

What is the Induced Fit Model?

Back

The Induced Fit Model suggests that the active site of an enzyme changes shape to better fit the substrate upon binding.

Front

What is the optimum pH for enzyme activity?

Back

The optimum pH is the pH at which an enzyme's activity is at its maximum.

Front

How does temperature affect enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it may denature and lose function.

Front

What is enzyme denaturation?

Back

Denaturation is the process where an enzyme loses its three-dimensional structure and, consequently, its activity due to extreme conditions.

Front

What role do enzymes play in metabolic pathways?

Back

Enzymes facilitate and regulate biochemical reactions in metabolic pathways, allowing for efficient energy and material processing.

Front

What is substrate specificity?

Back

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