Step by step
Solved in 3 steps
- Our biological fluids are much buffered by the biomolecules they contained. Name the two biomolecules that can act as the buffering components and briefly explain how these are done.Could the amino acid glycine serve as the basis of a buffer system? If so, in what pH range would it be useful?Why does the addition of acid have so much less of an effect on the pH of blood than it does on the pH of water?
- which of the following is a characteristic of a buffer? a. The pH will go down significantly when H3O+ is added to the buffer b. The pH will go down very slightly when H3O+ is added to the buffer c. The pH will go up significantly when H3O+ is added to the bufferWhen somebody experiences frequent vomiting, one possible side effect is that their blood pH can be disrupted afterwards. Understanding that after vomiting, stomach juice must be replaced, explain why the BLOOD pH might be affected, and whether you expect the pH to change to more basic or more acidic.Another characteristic of modern buffers such as HEPES is that their pH changes little with changes in temperature. Why is this desirable?
- The greatest buffering capacity at physiological pH would be provided by a protein rich in which of the following amino acids? Choose one from among the possible answers and explain. Serine Cysteine Alanine HistidineBased on the pH of your drug, if your drug was in a high concentration in the blood, how would it affect the pH of your blood. Would it cause acidosis or alkalosis, and how would you treat this? the drug name is captopril and the pH is 2.65What is the effect of adding a small amount of a strong acid or strong base to the acidity of a buffer? How would this compare to an unbuffered solution of the same acidity?
- In a hospital laboratory, a 10.0 mL sample of gastric juice, obtained several hours after a meal, was titrated with 0.01 M NaOH to neutral pH of 7.0; 72.0 mL of NaOH was required for this titration. The patient’s stomach contained no ingested food or drink, thus assume that no buffers were present. What was the pH of the 10.0 mL gastric juice sample before titrating with NaOH?Based on the pH of your drug, if your drug was in a high concentration in the blood,how would it affect the pH of your blood. Would it cause acidosis or alkalosis, and how would you treat this? drug Lipitor ph is 7 it's acidosis?What is NOT TRUE about buffers ?
