ADV9: Chemical Reactions Flashcard

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

Do allosteric inhibitors block the active site?

Back

False. Allosteric inhibitors bind to a site other than the active site, altering enzyme activity.

Front

What happens to enzymes when they are cooled down?

Back

The enzyme slows down due to reduced kinetic energy.

Front

What term describes all of the chemical reactions within each cell of an organism?

Back

Metabolism refers to all chemical reactions within a cell.

Front

What occurs in a synthesis reaction?

Back

In a synthesis reaction, two or more substances combine to form a new compound.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the alteration of an enzyme's structure, affecting its function.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts, speeding up chemical reactions without being consumed.

Front

What is a substrate in enzymatic reactions?

Back

A substrate is the reactant that an enzyme acts upon.

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions release energy, while endothermic reactions absorb energy.

Front

What is an active site?

Back

The active site is the region on an enzyme where substrates bind and reactions occur.
