Imagine a new type of cell was discovered on mars in an organism growing in benzene, a nonpolar liquid. the cell had a lipid bilayer made of phospholipids, but its structure was very different from that of our cell membranes.*part a: * describe what might be a possible structure for this new type of membrane. a.)this membrane would have the polar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophilic interior. b.) this membrane would have the nonpolar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophilic interior. c.) this membrane would have the nonpolar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophobic interior. d.) this membrane would have the polar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophobic interior.*part b: * *what might be characteristic features of the phospholipid head groups? a.)the phospholipid head groups would likely have equal numbers of hydroxyl and amino groups that would pack well and not be bulky. b.)the phospholipid head groups would likely have equal numbers of positively and negatively charged groups that would pack well and not be bulky. c.)the phospholipid head groups would likely bind to each other with covalent bonds that would pack well and not be bulky. d.)the phospholipid head groups would likely bind to each other with hydrogen bonding that would pack well and not be bulky

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression. c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression. d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
