Final answer:
Gramacidin disrupts ATP synthesis in bacteria, affecting their ability to produce energy and survive. This disruption can be used as a strategy for treating antibiotic-resistant gram-negative bacterial infections.
Step-by-step explanation:
Gramacidin affects cellular respiration by disrupting the process of ATP synthesis in bacteria. ATP, or adenosine triphosphate, is an important molecule that provides energy for cellular processes. By inhibiting ATP synthesis, gramacidin interferes with the ability of bacteria to produce energy efficiently, which can ultimately affect their survival. This disruption can be used as a strategy for treating bacterial infections caused by antibiotic-resistant gram-negative bacteria by combining Gramacidin with antibiotics.
