Enzymes

Front

What is the term for the phenomenon where each enzyme only has one specific substrate that fits its active site?

Back

Specificity

Front

What is the optimum pH for enzyme activity if a graph indicates maximum activity at pH 6.6?

Back

6.6

Front

What is the name of the region on an enzyme where substrate molecules bind?

Back

Active site

What is the term used to describe a biological catalyst that speeds up chemical reactions?

Back

Enzyme

Front

What are the substances called that are produced as a result of an enzyme-catalyzed reaction?

Back

Products

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 decreases due to denaturation.

Front

What is the role of cofactors in enzyme activity?

Back

Cofactors assist enzymes in catalyzing reactions, often by stabilizing the enzyme-substrate complex.

Front

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

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different site, altering enzyme function.

Front

How does substrate concentration affect enzyme activity?

Back

Increasing substrate concentration generally increases enzyme activity until the enzyme becomes saturated.

Front

What is enzyme denaturation?

Back

Denaturation is the process where an enzyme loses its functional shape due to factors like extreme pH or temperature.
