Enzyme Review (2024)

Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes lower the activation energy required for reactions, thus speeding up the rate of reaction.

Front

What happens to enzyme activity at high temperatures?

Back

Enzyme activity typically decreases at high temperatures due to denaturation, which alters the enzyme's structure.

Front

What is the optimal temperature for most human enzymes?

Back

The optimal temperature for most human enzymes is around 37°C.

Front

What is the active site of an enzyme?

Back

The region on the enzyme where the substrate binds and the reaction occurs.

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon.

Front

What is enzyme denaturation?

Back

The process in which an enzyme loses its functional shape due to external factors like temperature or pH.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to decreased activity or denaturation.

Front

What is enzyme specificity?

Back

The ability of an enzyme to choose exact substrates from a group of similar chemical molecules.

Front

What is a cofactor?

Back

A non-protein chemical compound that is required for the biological activity of some enzymes.
