NEET BIOLOGY

Detailed explanation-1: -Fibrinogen-related proteins (FRePs) contain a common and ancient domain that has evolved to play key roles in tissue repair.

Detailed explanation-2: -Beyond the stem cell, three other types of cells are critical to the process of tissue repair: fibroblasts, endothelial cells and macrophages. In most wounds, complete replacement of wounded tissue to its original, unharmed state is impossible.

Detailed explanation-3: -The muscle damage initiates a repair process in which certain hormones, along with the macronutrient protein, synthesize new satellite cells, which are used to repair the damaged muscle fibers. In other words, the role of protein is to help repair tissues damaged by exercise.

Detailed explanation-4: -Protein is one of the most important nutrient factors affecting wound healing. A deficiency of protein can impair capillary formation, fibroblast proliferation, proteoglycan synthesis, collagen synthesis, and wound remodeling.

Detailed explanation-5: -The complicated mechanism of wound healing occurs in four phases: hemostasis, inflammation, proliferation, and remodeling.
