What is the main reason ribozymes are exempted from the classification of most enzymes as proteins?
What is the main reason ribozymes are exempted from the classification of most enzymes as proteins?
- They are RNA molecules, not proteins (correct)
- They are larger than typical enzymes
- They are not specific to a substrate
- They are not involved in catalyzing reactions
What happens to the active site of an enzyme when it is dissociated into subunits?
What happens to the active site of an enzyme when it is dissociated into subunits?
- It loses its ability to attract cofactors
- It is disrupted, affecting the enzyme's catalytic activity (correct)
- It becomes more specific to a substrate
- It becomes more efficient in accelerating reactions
What is the role of cofactors in enzyme activity?
What is the role of cofactors in enzyme activity?
- Provide additional chemical components that are mostly inorganic ions (correct)
- Act as substrates for the enzyme
- Enhance the specificity of the enzyme to a substrate
- Increase the size of the enzyme
