Answer:
The correct answer is - option A. IKK.
Explanation:
In signal transduction or any other molecular biology process, the upstream or downstream is related to the molecular or cellular events that follow a mechanistic and temporal order.
In TNF signaling involved in cell survival pathway the TRADD- associated complex also is known as TNF receptor-associated death domain complex has a second messenger that activates temporally after the cell membrane receptor known as IKK signaling protein that help in numerous downstream pathways.
Thus, the correct answer is - option A. IKK.

B

R-values of insulation affects the environment by making it a user friendly substance safe for living organisms since it helps <span>monitor heat resistance into the environment. In addition, it is also for protection from pollution. Hope this answers your question.</span>
Facilitated diffusion is the term
given for passive transport of molecules or ions across a biological membrane, facilitated
by transport proteins. The molecules or ions move down a concentration
gradient; therefore, no chemical energy is required and no ATP hydrolysis is
needed. The transport proteins may be responsible for carrying larger molecules
across the membrane by changing their conformation, or water-soluble transport
proteins may carry non-polar molecules with poor water solubility across. Since
no energy is involved in the diffusion, options a) and c) are incorrect. Since
the molecules being carried are not altered in any way, option d) is incorrect.
Option b) ‘transport proteins provide a hydrophilic route for the solute to
cross the membrane’ is correct as water-soluble carrier proteins are able to facilitate
the diffusion of non-polar molecules with poor water solubility.
