Ligase helps in which of the following reactions?
Correct answer: C. Joining of molecules
- A. Splitting of two molecules
- B. Oxidation of molecules
- C. Joining of molecules
- D. Both Options A and B are correct
Explanation
This option is correct. Ligase enzymes are specifically involved in catalyzing the joining or ligation of two molecules. They facilitate the formation of covalent bonds between the molecules, often using ATP as an energy source. Ligase enzymes play a crucial role in various cellular processes, such as DNA replication and DNA repair, where they seal gaps in the DNA strands by joining the nucleotides.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
