The Importance of Phosphorylation in Biological Systems

🔑Phosphorylation of glucose makes it harder for it to leave the cell, ensuring cellular glucose retention.

🔬Hexokinase is an enzyme that facilitates the phosphorylation of glucose by providing ions to keep the electrons busy during the nucleophilic attack.

💡The exergonic nature of the glucose phosphorylation reaction makes it energetically favorable.

⚛️The coupling of glucose phosphorylation with the hydrolysis of ATP provides the energy required for the reaction to occur.

🧪Phosphorylation of glucose is an essential input for various cellular processes.
