ATP/Energy and Enzymes Review

Front

What is metabolism?

Back

All of the chemical reactions that occur within a cell in an organism.

Front

What are detritivores?

Back

Heterotrophs that 'clean up' the ecosystem by eating dead and decaying organisms.

Front

Which bond of the ATP molecule is broken to release energy?

Back

The bond labeled A.

Front

What is a catabolic process?

Back

A process in which large molecules are broken down.

Front

How do enzymes increase the speed of chemical reactions?

Back

By reducing the activation energy.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy carrier in cells.

Front

Define autotrophs.

Back

Organisms that produce their own food from inorganic substances.

Front

What is the difference between anabolic and catabolic reactions?

Back

Anabolic reactions build larger molecules from smaller ones, while catabolic reactions break down larger molecules into smaller ones.

Front

What is activation energy?

Back

The minimum energy required for a chemical reaction to occur.

Front

What is the function of enzymes in biological systems?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed.
