AP Biology Metabolism

Front

What are enzymes made up of?

Back

Enzymes are made up of amino acids.

Front

What is the likely result of a mutation in a DNA sequence coding for an enzyme?

Back

The enzyme will most likely fold in a way that makes its shape incompatible with the substrate and the enzyme will not function correctly.

Front

What does the first law of thermodynamics state?

Back

Energy cannot be created or destroyed.

Front

What can be concluded if changing the pH from 7 to 6 increases product formation?

Back

The enzyme was in a more active shape at pH 6.

Front

What type of reaction is represented by AB --> A + B?

Back

Catabolic reaction.

Front

Define metabolism.

Back

Metabolism is the sum of all chemical reactions that occur within a living organism to maintain life.

Front

What is the role of enzymes in metabolic reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is an anabolic reaction?

Back

An anabolic reaction is a metabolic pathway that constructs molecules from smaller units, typically requiring energy.

Front

What is a catabolic reaction?

Back

A catabolic reaction is a metabolic pathway that breaks down molecules into smaller units, releasing energy.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrate molecules, which is crucial for metabolic efficiency.
