Question

Amphiphilic molecules, such as phospholipids spontaneously form micelles/vesicles in water because: a) The entropy of the detergent increases b) The enthalpy overcomes the entropy c) The entropy of water increases d) The change in free energy is positive e) When water interacts with the hydrophobic groups in the detergent, the water becomes less ordered Question 2: Which of the following reactions represent a deamination reaction? S + 2H + 2e c) H2CO3 + H20 = H30+ + HCO3 но нR HC 0. + HORH несмс-сон HORH HOH d) Question 3: Which statement best describes, AG, AH and AS. a) AG is positive for spontaneous reactions; AH is the quantity measured in an laboratory setting and AS tends to increase. b) AG is negative for spontaneous reactions; AH is the quantity measured in an laboratory setting and AS tends to decrease. c) AG is negative for spontaneous reactions; AH is the quantity measured in an laboratory setting and AS tends to increase. d) AG is is the quantity measured in an laboratory setting, AH negative for spontaneous reactions; and AS tends to increase.
