Correct option is (a) True
To explain: Coagulation of proteins or a certain mechanism is a reason for the death of cells observed by the following experiment – a suspension containing 99% dead calls had their enzyme activity still on. This experiment shows that enzyme activity has nothing to do with death but inhibition of growth does. Hence, these cells mus have had their enzyme activity nullified only when all the protein/mechanisms in their body were coagulated. Therefore, the statement – Decreasing enzyme content is not a cause but rather a consequence of inhibited growth, holds true.
