Question

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

Answer 1

A coenzyme is a naturally occurring non-protein compound that collaborates with a catalyst to catalyse a reaction. Coenzymes are frequently referred to as cofactors, but they are synthetically distinct. A coenzyme cannot function on its own, but it can be reused several times when combined with a compound.

Complete answer:
$NAD^{+}$ and $FAD$ are co-compounds needed for the fulfilment of numerous biochemical pathways. Be that as it may, there is no requirement for a gigantic measure of union of both of these co-chemicals as there is a component of reusing the co-proteins after fruition of one stage in the metabolic pathway. These co-compounds are prevalently needed for the blend of $ATP$ (energy currency of the cell) and will be utilized in the electron transport chain for the creation of the equivalent. Thus, they are not needed to be incorporated in tremendous amounts however they assume a vital part in cell energetics.
When a chemical acquires a coenzyme, it transforms into a holoenzyme or Active enzyme. Active enzymes convert substrates into the items required by an organic entity to perform fundamental functions, whether compound or physiological. Coenzymes, like proteins, can be reused and reused without affecting their response rate or viability. They connect to a segment of the dynamic site on a protein, allowing the catalysed response to occur.

Hence. Option B-False is the correct option.

Note:
An apoenzyme is a protein that lacks a coenzyme. Chemicals cannot catalyse reactions effectively in the absence of coenzymes or cofactors. To be honest, the chemical may not have any capacity at all. If responses cannot happen at the normal catalysed rate, a creature will have difficulties supporting life.
