1.	When the pH of a protein is lowered _________________________(a) temperature decreases(b) negatively-charged groups neutralize(c) positively-charged groups neutralize(d) positively-charged groups decreaseThe question was posed to me in an online interview.My doubt is from Protein Techniques topic in portion Techniques in Cell Biology of Cell Biology
Answer» RIGHT CHOICE is (b) NEGATIVELY-charged groups neutralize To explain: When the pH (potential hydrogen) of a protein is lowered, the negatively charged groups BECOME NEUTRALIZED whereas the positively-charged groups become abundant. The opposite occurs when the pH increases.
