Question

Lysis of marine algae and cyanobacteria releases the major osmoregulatory solute, dimethylsulfoniopropionate (DMSP), which is degraded into the most abundant organic S compound in nature, ________.

A) dimethyl sulfide (CH₃-S-CH₃)
B) hydrogen sulfide (H₂S)
C) gypsum (CaSO₄)
D) elemental sulfur (So)

Answer 1

The degradation of DMSP by bacteria leads to the formation of dimethyl sulfide (DMS), which is significant for cloud formation and climate. The correct answer is A) dimethyl sulfide (CH₃-S-CH₃).

Step-by-step explanation:

The lysis of marine algae and cyanobacteria releases dimethylsulfoniopropionate (DMSP), which is then degraded by bacteria into dimethyl sulfide (DMS).

DMS is considered the most abundant organic sulfur compound in nature and plays a crucial role in global climate through its influence on cloud formation. The correct answer to the question is A) dimethyl sulfide (CH₃-S-CH₃).
