Moist heat cause_and kill the microbes:

Explanation

Moist heat can cause the coagulation or denaturation of proteins. When proteins are exposed to high temperatures, their three-dimensional structure can be disrupted, leading to the loss of their functional shape. This process is often irreversible and causes the proteins to form clumps or solidify, which can be detrimental to the survival of microbes. The coagulation of proteins can result in the inactivation or destruction of essential microbial enzymes and structures, ultimately killing the microbes. In summary, moist heat primarily causes the coagulation of proteins, which leads to the inactivation of microbial enzymes and structures, ultimately killing the microbes. While the degeneration of nucleic acids and the bursting of cells can also occur, they are generally secondary effects in the context of microbial death caused by moist heat.
