Transcript text: Composed principally of amino acids, and acting as biological catalysts, $\qquad$ facilitate metabolic activities of the cell. cofactors ribosomes enzymes ribozymes

Solution

The answer is the third one: enzymes.

Explanation for each option:

Cofactors: These are non-protein chemical compounds or metallic ions that are required for a protein's biological activity to happen. They are not composed principally of amino acids, so this option is incorrect.
Ribosomes: These are complex molecular machines found within all living cells that perform biological protein synthesis (translation). They are not primarily composed of amino acids, but rather of ribosomal RNA and proteins, so this option is incorrect.
Enzymes: These are proteins composed principally of amino acids that act as biological catalysts, facilitating metabolic activities of the cell. This option is correct.
Ribozymes: These are RNA molecules that can catalyze specific biochemical reactions, similar to the action of protein enzymes. They are not composed principally of amino acids, so this option is incorrect.

In summary, enzymes are the correct answer as they are composed of amino acids and act as biological catalysts in metabolic processes.
