Question

Scenario A: Marry returns home to prepare supper, while busy peeling vegetables her phone rings and she gets distracted. She puts the knife down at the edge to of the countertop to answer her phone. On the line is her sister with good new. While excited with the news she receives, she slams her hand down in the countertop. The knife she was using falls and cuts her on the right leg. The cut is 10 mm deep and she bleeds. During the process, Mary overstretched and also sustained a muscle strain injury. A6. Mary read an article by Tipton (2011), which explains that “nutrition is important for optimal wound healing”. Mary now understands that the most important consideration for her now is to avoid malnutrition so that she can experience an optimal increase in muscle protein synthesis which would allow for wound healing. Please explain to Mary the process of protein synthesis and how this will help with her wound healing. (10) Please can I get a thorough explanation for A6. It is worth 10 marks. Please do not forget to explain the process of protein synthesis

Answer 1

Many factors have an effect on the wound healing process, and the main is your nutrition level in food. Balanced glucose levels, adequate vitamin C and ample Ca, for example, are necessary for healing process. Another huge contributor to recovery from wounds is protein. once your body doesn’t get enough of this essential amino acids, collagen synthesis becomes limited. Collagen is a tissue binding proteins, thus importent to regenerate affected tissue. Sadly, the wound healing process can it self lose protein. The body can lose up to one hundred milligrams of protein per day because of exudation, or fluid leak from the affected body part. For this reason, a high protein diet is important throughout recovery.

we get our proteins from our diet. The food is disintegrated within the digestive system and absorbed in the blood flow. The amino acids are building blocks of proteins. These amino acids, obtained from the diet are either directly used for protein synthesis or are modified to new amino acids (or used as fuel).

Protein synthesis is the biological method, occurring inside cells, balancing the loss of cellular proteins through the synthesis of new ones. protein synthesis is divided generally into 2 phases - transcription and translation. The transcription process involves synthesis of a template molecule (called mRNA) from the protein-coding region of DNA, known as a gene. This conversion is performed by enzymes, called RNA polymerases, within the nucleus of the cell. Through the translation, the messenger RNA is scan by ribosomes which use the nucleotide sequence of the messenger RNA to construct the sequence of amino acids. The ribosomes catalyze the formation of peptide bonds between the encoded amino acids resulting in a polypeptide chain. Following translation the peptide chain should fold to make a useful 3D structure, for instance, to perform as a catalyst the peptide chain should fold properly. Once properly folded, it will undergo additional maturation process through different post-translational modifications. Post-translational modifications will alter the protein's ability to perform. Thus new proteins are made.

In a nutshale, the process need the building blocks to regenerate damaged tissue. Our diet supplies that building block (amino acids).
