Which statement is true regarding zinc in wound healing?

Zinc plays a crucial role in wound healing, primarily by increasing growth factor production, which is essential for various phases of the healing process. Growth factors are proteins that stimulate the proliferation, migration, and differentiation of cells involved in tissue repair, such as fibroblasts and keratinocytes. The presence of adequate zinc levels ensures that these growth factors are produced and activated, thereby facilitating the healing process.

Furthermore, zinc also contributes to collagen synthesis, modulates inflammatory responses, and helps maintain cell membrane integrity, which are all vital for effective wound healing. By enhancing the overall wound healing environment, zinc supports the reparative processes that lead to tissue regeneration and recovery.
