Symptoms of coeliac disease include poor growth. Suggest why a person with coeliac disease might have this symptom.

to answer this question we need to understand the different components involved in growth in particular, glucose and proteins. we also need to understand the role of villi and what happens to them in coeliac disease. //proteins are the macromolecules required for growth. during digestion, proteins are broken down into amino acids. amino acids are essential for protein synthesis and thus growth. they are absorbed by the small intestines during digestion.// protein synthesis is a process which requires energy. most biological require ATP energy. ATP is formed as a result of respiration. glucose is an essential reactant for this reaction and is absorbed by the small intestines during digestion.//answer: villi are microscopic structures that increase the surface area for absorption. in coeliac disease, these are destroyed and so the surface area for absorption is reduced. therefore the absorption of glucose and amino acid is impaired. this leads to reduced respiration and thus ATP energy. the lack of ATP energy means that less protein synthesis takes place and thus growth is impaired as a result
