Question
When a substrate is being metabolised, why does not all the energy that is produced get released in one step? It is released in multiple steps. What is the advantage of stepwise release?

Answer

The stepwise release of energy have advantage to the cell. Because if all the energy from the glucose would be released at once then most of it would be lost in the form of light and heat. This energy is trapped in ATP is utilised in various energy requiring processes of the organisms and for the synthesis of other biomolecules in the cell.

Kavita (student of class VIII) returned from the school and started counting her teeth. She felt surprised and counted her teeth two more times, but each time she count, she found her teeth to be 28 in number. Then, she started counting his younger brother (student of class I) teeth and found them to 20 in number. She rushed to his father who was a dentist and told him, that her teacher taught her that human beings have 32 teeths. But she has only 28 and his brother has 20. Her father explained that number of teeth are related to the age of a child and also told her about diphyodont and heterodont dentition.
