Question
The protein PGC-lal increases in skeletal muscle during exercise. The protein produces an enzyme called KAT which turns the harmful kynurenine molecule (which leads to depression) into harmless kynurenic acid which can be passed easily out of the body. (This is true). You are studying four different exercise regimes and you are measuring the concentration of kynurenic acid in the urine. Your four exercise regimes are: control no exercise, 30 minutes of biking three times a week; progressive resistance exercise (weight lifting) for 30 minutes three times a week, and a swimming laps for 30 minutes 3 times a week. You assay for kynurenic acid at the end of 90 days. Your data are in ug/l Below are your data: (2.5 points) 18 28 16 40 wimmin 40 29 36 46 51 36 42 49 42Explanation / Answer
No, this is not ture. Harmful Kynurenine molecule converted into harmless kynurenic acid and passed in urine. In control group without excerise the concentration of kynurenic acid in urine is high 51ug/ml compare to the excerised person. It clearly shows that due to excercise concentration of kynurenic acid in urine is decreased.
Weight lifting drmatically decrease the output of kynurenic acid in the urine. Biking and swimming not decrase that much compare to weight lift.
