Question 1 Not yet answered Marked out of 1.00 The chemical structure shown below is for sodium lauryl sulfate, a commonly used laboratory detergent. If you added this chemical to a culture of bacteria, they lyse. What would be a reasonable cause for this action on the cells? NOTE: Multiple answers may be correct Flag question -O Select all that apply: O a. Many SDS molecules in solution will form a micelle due to the hydrophobic tails and the cross out hydrophilic head. O b. The negatively charged oxygen atom would be exposed on the hydrophilic O c. The amphipathic nature of this molecule can result in SDS inserting into the O d. The nonpolar portion of SDS can form van der Waals interactions with the surface of the membrane. cross out cell membrane. cross out hydrocarbon chains of the phospholipids. cross out

Explanation / Answer

1) a & c option is correct because SDS is a anioinic detergent and form micelles with the help of hydrophobic tail and due to its amphipathic nature it can insert into cell membrane.

2) c option is right because leucine is actively transported with Na+ while other amino acids are transported by facilitated diffusion.

4) c & d should be the right answer because cynide inhibits the electron transport by inhibiting the synthesis of ATP and thus trasport of lactose.

5) only a option is relevent to this question because receptor mediated endocytosis required clatherin to form endocytic vesicle so here ethanol block clatherin association.
