Front

What happens to an enzyme when the pH is outside of its optimal range?

Back

Denaturing of the enzyme.

Front

What is the bond between adjacent amino acids called?

Back

Peptide bond.

Front

What parameter affects enzyme rate as shown in a graph?

Back

Substrate concentration.

Front

How is lactose-free milk produced?

Back

By passing it through a column of alginate beads with immobilized lactase.

Front

What parameter affects enzyme rate as shown in a graph?

Back

pH.

Front

What is the primary structure of a protein?

Back

The sequence of amino acids in a polypeptide chain.

Front

What is denaturation in proteins?

Back

The process where proteins lose their structure and function due to external stress, such as extreme pH or temperature.

Front

What is the role of enzymes in biochemical reactions?

Back

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

Front

What is the significance of enzyme-substrate specificity?

Back

Enzymes are specific to their substrates, meaning each enzyme only catalyzes a specific reaction.

Front

What is the effect of temperature on enzyme activity?

Back

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