Front

What type of process involves the building of complex molecules from simpler ones?

Back

Synthesis

Front

Front

What type of reaction is represented by the equation A --> B + C?

Back

Catabolic

Front

What is the role of enzymes in biochemical reactions?

Back

To act as catalysts that speed up reactions without being consumed.

Front

What is the term for the specific region on an enzyme where the substrate binds?

Back

Active site

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration.

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 part of the enzyme.

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.
