Daily Review - Enzymes (Task 5 Part 2)

Front

What is the function of an enzyme?

Back

Enzymes speed up chemical reactions.

Front

What is indicated by the term 'active site'?

Back

The active site is the region on an enzyme where substrates bind and undergo a chemical reaction.

Front

What temperature does this enzyme work best?

Back

Enzymes typically have an optimal temperature at which they function most efficiently; for this enzyme, it is 30°C.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What is the optimal pH of enzyme A?

Back

The optimal pH of enzyme A is 2.

Front

Define 'enzyme'.

Back

An enzyme is a biological catalyst that accelerates chemical reactions in living organisms.

Front

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, altering their structure and function.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.

Front

What role do cofactors play in enzyme activity?

Back

Cofactors are non-protein molecules that assist enzymes in catalyzing reactions.

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.
