Verified step by step guidance

Understand the role of exoenzymes: Exoenzymes are enzymes secreted by pathogens that function outside of the cell. They play a crucial role in the disease process by interacting with the host's environment.

Identify the main functions of exoenzymes: Exoenzymes typically help in breaking down host tissues, facilitating nutrient acquisition, and sometimes evading host immune responses by altering the host's environment.

Consider the option 'Directly killing host cells': Exoenzymes generally do not directly kill host cells. Instead, they modify the environment or degrade tissues to aid in the pathogen's survival and proliferation.

Compare the options: Evaluate each option based on the typical functions of exoenzymes. Breaking down host tissues and facilitating nutrient acquisition are common roles, while directly killing host cells is not.

Conclude which option is not a main role: Based on the understanding of exoenzyme functions, determine that 'Directly killing host cells' is not a main role for exoenzymes in the disease process.
