Which of the following is a complication of muscle catabolism?

Muscle catabolism, which refers to the breakdown of muscle tissue, can lead to several complications, one of which is delayed wound healing. When the body experiences catabolism, particularly in a burn or trauma situation, the proteins and amino acids that would typically aid in tissue repair and regeneration are diminished. This reduction in available resources adversely affects the body's ability to heal wounds effectively. With an inadequate supply of these necessary building blocks, the synthesis of new tissues slows down, resulting in prolonged recovery times and an increased risk of complications related to wounds, such as infections or non-healing.

The other choices do not align with the effects of muscle catabolism. For instance, growth acceleration and increased regenerative capacity suggest a positive response that is contrary to the consequences of catabolic processes. Decreased insulin resistance typically indicates improved metabolic function, which is also not a result of muscle breakdown but rather the opposite. In this context, muscle catabolism is associated with negative health outcomes, particularly concerning wound healing.
