your presentation skills are really effective, this was really helpful :)

Really useful. And im not even in bio

There is a peculiar phenotype of thinness called constitutional thinness, which is described in scientific literature. It is defined by a state of non-pathological low body weight stable over time, in which from early childhood these people remain in the lowest percentiles adjusted for age, sex, etc. They are people with a normal caloric intake but exhibit resistance to weight gain despite the obesogenic environment of the modern world. In 2019, an in-depth study was carried out on this peculiar phenotype, in which people with said phenotype and people with normal weight were brought together and white adipose tissue was compared and studied in both groups. The results were that evidently the adipocytes of these particular thin people were noticeably smaller than the control group, they contained a greater number of mitochondria, which translated into a greater oxidation of fatty acids but also surprise in the synthesis of triglycerides. In the blood, the lipids were balanced, with no evidence of hypertriglyceridemia, so they are healthy people. In addition, not only was there an increase in mitochondrial number but there was elevated activity of the electron transport chain. The scientists did not find the presence of the uncoupling protein as a possible explanation for the energy expenditure in these people. We also wanted to see if there was a greater oxidation of lipids in the skeletal muscle, but in neither of the two groups were there differences in the oxidative capacity, which is why the study postulates that the increased lipid metabolism in these thin people is specific to adipose tissue. white, but not of mitochondrial biogenesis. The study ends by stating that mitochondria are key to local adiposity and could be a target for better treatments for obesity. I present this phenotype of constitutional thinness, I have a BMI that fluctuates from 16.3 to 17.5 at most. I was always like this, since I was little I moved through the lowest percentiles. The interesting thing for me is that it is as if the white adipose tissue of us constitutionally thin people is atypical since it is assumed that white tissue does not contain many mitochondria, but ours demonstrates the opposite. Quite curious What do you think? The study can be found as follows. Low body weight in humans is associated with high mitochondrial activity in white adipose tissue. I recommend that you read it. It's interesting.

informative , thank u

this is histology but you're explaining biochemistry

where are the practice questions

nice
