Cells were treated with a chemical that inhibits the first step of the electron transport chain. How would this affect the levels of the inputs and outputs of the electron transport chain?

The levels of inputs and outputs will be negatively affected

Please find the detailed explanation below

Explanation:

The electron transport chain consists of a series of molecules that transfers electrons to one another in a group called COMPLEXES. The major aim of the ETC is to build a proton gradient needed for the synthesis of ATP. The first step in the ETC is as follows:

The process of ETC starts when two electron carriers/donors viz: NADH and FADH2 transfers their electrons to COMPLEX I. If this does not occur, the ETC cannot function. Hence, in a case where cells were treated with a chemical that inhibits the first step of the electron transport chain, the input and output (ATP) will be greatly affected in the sense that other inputs will not be used or the output will not be produced.
