Question

on 28 of 33 Sapling Learning Map do Determine how feedback inhibition of enzyme 1 by a high concentration of product Z affects the concentrations of the different substrates for the following reaction pathway. Assume that product Z diffuses out of the cell. enzyme 1 enzymeenzyme 3 The concentration of X Select answer remains the same The concentration of Y Select answer The concentration of Z Select answer What happens if the concentration of Z decreases? O Enzyme 1 activity increases O Enzyme 2 activity stops O Enzyme 3 regains its shape. O Enzyme 1 becomes inactive O Previous Gr: Up&V;,ew Sciul'on e Check Answer 0 Next Exit int

Explanation / Answer

By feedback inhibition, a gorwing amount of the product signals an initial component or reactor to stop carrying out the reaction anymore till overly high levels subside to normalcy.
As such, when a high concentration of Z prevails.
The concentration of X will decrease as enzyme 1 will be rendered inactive.
The concentration of Y will decrease as availability of X will go down.
The concentration of Z will decrease as it will go out of the cell.

If the concentration of Z goes down, then any change that occurs will be favourable for the reaction in the forward direction leading to more production of Z. As such, Enzyme 1's activity will icnrease.
