Proteins and Enzymes

Front

What is the primary function of proteins in the body?

Back

Proteins serve various functions including structure, transport, and catalyzing chemical reactions, but they do NOT store genetic information.

Front

What happens if the shape of an enzyme is altered?

Back

If the shape of an enzyme is changed, it will not work properly.

Front

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

Back

Substrate.

Front

What is the optimum pH for enzyme activity?

Back

The optimum pH is the pH at which an enzyme is most active; for some enzymes, this may be around 6.6.

Front

What are the building blocks of proteins?

Back

Amino Acids.

Front

What role do enzymes play in chemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its shape and functionality due to external factors like temperature or pH changes.

Front

How do temperature changes affect enzyme activity?

Back

Increased temperature can increase enzyme activity up to a certain point, after which the enzyme may denature and lose function.

Front

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

Back

Competitive inhibitors bind to the active site of an enzyme, while non-competitive inhibitors bind to a different site, altering enzyme function.

Front

What is an enzyme's active site?

Back

The active site is the specific region of an enzyme where substrate molecules bind and undergo a chemical reaction.
