Step 1: Understanding the Concept
The liver is the largest gland. It detoxifies, stores glycogen, makes plasma proteins and forms urea.
Step 2: Check the statements
Kupffer cells are fixed macrophages and help in detoxification.
Ammonia from deamination is converted into urea in the liver.
Excess glucose is stored as glycogen.
Step 3: Find the wrong one
Fibrinogen and prothrombin are plasma proteins that the liver does synthesise. Saying they are not produced in the liver is wrong.
Final Answer:
The incorrect statement is that fibrinogen and prothrombin are not produced in the liver.
\[ \boxed{\text{(B) }\text{Blood proteins such as fibrinogen and prothrombin are not produced in liver.}} \]
