During fatty acid synthesis, acetyl-CoA is carboxylated to form this other key molecule.

What is Malonyl-CoA?

300

This type of monotopic transmembrane protein contains an internal signal sequence. Its N terminus is on the cytoplasm. 

What is type 2 TM protein? 

300

This is a protein with a sugar chain which activates as a response of inflammatory response in endothelial cells.

What is Selectin?

300

This is a major component of the cell wall of gram-positive bacteria, composed of a glycerol-phosphate polymer.

What is Lipoteichoic Acid (LTA)?

300

The T183A mutation in PRNP is known to cause genetic prion
disease. The sequence surrounding position 183
is as follows:

Normal: 180-VNITIKQH-187
Disease: 180-VNIAIKQH-187

This is an essential site that is removed by the T183A mutation.

What is N-gycosylation?

500

This is the hydrolysis of triacylglycerols with a base (such as sodium hydroxide) to produce glycerol and fatty acid salts (soap).

What is Saponification?

500

Nuclear receptors, such as the steroid hormone receptors, contain this number of transmembrane domains.

What is 0?

500

The following sequence, which is present within the loop between transmembrane domains #1 and #2 of a Type-IV transmembrane protein that has its N-terminus in the cytoplasm, is expected to have this many N-glycans added to it:

…DRINASHGMNPTTSNNSTQVTNAGTCWNKSE…

What is 4?

500

This isoprene-derived molecule is the scaffold upon which N-glycans are assembled in the endoplasmic reticulum membrane.

What is dolichol phosphate?

This type of CJD is transmitted during a medical procedure.

What is iatrogenic CJD?

800

This electron acceptor from the fourth step of fatty acid β-oxidation can generate 2.5 molecules of ATP in its reduced form.

What is NAD?

800

If 2 ATP is hydrolyzed in a Na+/K+ ATPase, this number of Na+ goes to the ER lumen while this number of K+ goes out of the ER lumen.

What is 6 Na+ and 4K+?
800

This post-translational modification which helps to anchor proteins to the inner leaflet of the plasma membrane, involves the attachment of a lipid molecule via a glycine residue.

What is N-myrsitoyl?
