SOL Biochemistry and Enzymes

Front

What type of bond results from the gain or loss of electrons?

Back

Ionic bond: A bond formed when one atom transfers electrons to another, resulting in charged ions that attract each other.

Front

What do all enzymes do?

Back

Enzymes affect the rate of chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What does the pH scale measure?

Back

The pH scale measures the strength or weakness of an acid or base, indicating whether a substance is acidic, basic, or neutral.

Front

At what temperature does the enzyme in the graph work best?

Back

30 C: The optimal temperature for enzyme activity, where the reaction rate is highest.

Front

What is the active site of an enzyme?

Back

Active site: The specific region on an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between atoms, resulting in partial positive and negative charges.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where electrons are shared equally between atoms, resulting in no charge difference.

Front

What is a hydrogen bond?

Back

A hydrogen bond is a weak attraction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

Front

What is the role of enzymes in biological systems?

Back

Enzymes act as catalysts in biological systems, speeding up chemical reactions without being consumed in the process.

Front

What is the significance of enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate, ensuring that only certain reactions occur.
