Question

State whether the following statements are true or false.
Since $NA{D}^{+}$ and FAD are critical coenzymes in cellular respiration, huge quantities must be synthesized in the cell to ensure there is no shortage.

• A. True
• B. False

Answer 1

The correct option is B False

NAD+ and FAD are co-enzymes required for the completion of many biochemical pathways. However, there is no need for an enormous amount of synthesis of either of these co-enzymes as there as a mechanism of recycling the co-enzymes after completion of one step in the metabolic pathway. These co-enzymes are predominantly required for the synthesis of ATP (energy currency of the cell) and will be used in the electron transport chain for the production of the same. So, they are not required to be synthesized in huge quantities but they play a crucial role in cell energetics.

So, the correct statement is 'False'.
