Enzyme Review Flashcard

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What does a pH of 3 indicate about a solution?

Back

A pH of 3 indicates a highly acidic solution with a high concentration of hydrogen ions (H+).

Front

What does a pH of 10 indicate about a solution?

Back

A pH of 10 indicates a basic solution with a lower concentration of hydrogen ions (H+) and a higher concentration of hydroxide ions (OH-).

Front

What are hydroxide ions (OH-)?

Back

Hydroxide ions (OH-) are negatively charged ions that indicate the basicity of a solution; higher concentrations of OH- result in higher pH values.

Front

What are hydrogen ions (H+)?

Back

Hydrogen ions (H+) are positively charged ions that indicate the acidity of a solution; higher concentrations of H+ result in lower pH values.

Front

Where are acids found on the pH scale?

Back

Acids are found below 7 on the pH scale.

Front

Where are bases found on the pH scale?

Back

Bases are found above 7 on the pH scale.

Front

What happens when hydrogen peroxide is mixed with a boiled potato?

Back

When hydrogen peroxide is mixed with a boiled potato, it produces a clear liquid with no bubbles due to the absence of active enzymes.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes lower the activation energy required for reactions, allowing them to occur more quickly and efficiently.
