Final answer:
The question regarding CRP (C-reactive protein) and MBL (mannan-binding lectin) pertains to whether they are soluble. The answer is: a) True Both CRP and MBL are soluble proteins that have different functions in the body. CRP is produced in response to inflammation and MBL aids in the immune response against pathogens.
Step-by-step explanation:
CRP stands for C-reactive protein and MBL refers to mannose-binding lectin. Both CRP and MBL are indeed soluble proteins.
CRP is an acute-phase protein produced by the liver in response to inflammation. It becomes soluble and circulates in the blood during an acute phase response. Elevated levels of CRP in the blood indicate the presence of inflammation in the body.
MBL is a soluble protein that plays a role in the innate immune response against pathogens. It binds to sugar molecules on the surface of microbes and triggers the activation of the complement system to destroy the pathogens.
