globulins Flashcards
(24 cards)
What are globulins?
Globulins are a group of proteins in the blood that play various roles, including immune function and transport.
What is the primary function of fibrinogen?
Fibrinogen is a protein that is essential for blood clotting, as it is converted into fibrin during the coagulation process.
True or False: Albumin is the most abundant protein in human plasma.
True
Fill in the blank: Globulins are classified into three main groups: alpha, beta, and _____ globulins.
gamma
What role do albumins play in the body?
Albumins help maintain osmotic pressure and transport various substances in the blood.
Which plasma protein is primarily responsible for maintaining oncotic pressure?
Albumin
True or False: Fibrinogen is produced by the liver.
True
What is the molecular weight of albumin approximately?
Approximately 66,500 Da (Daltons)
What is the significance of gamma globulins?
Gamma globulins are involved in the immune response, particularly as antibodies.
Multiple Choice: Which of the following is NOT a function of globulins? A) Transport, B) Immune response, C) Energy storage
C) Energy storage
What happens to fibrinogen during the clotting process?
Fibrinogen is converted into fibrin, which forms a mesh that helps to stop bleeding.
Fill in the blank: Albumin levels can be affected by _____ conditions such as liver disease.
pathological
What are the three main types of globulins?
Alpha globulins, beta globulins, and gamma globulins.
True or False: Fibrinogen is found in serum.
False
How does albumin affect drug distribution in the body?
Albumin binds to many drugs, affecting their distribution and availability in the bloodstream.
What can low levels of albumin indicate?
Low levels of albumin can indicate liver disease, kidney disease, or malnutrition.
Multiple Choice: Which globulin is primarily responsible for transporting iron? A) Alpha globulins, B) Beta globulins, C) Gamma globulins
B) Beta globulins
What is the main source of albumin production in the body?
The liver
True or False: Fibrinogen is a soluble protein in plasma.
True
What is the role of alpha globulins?
Alpha globulins are involved in transport and also play roles in the immune response.
Fill in the blank: The main function of beta globulins is to transport _____ in the blood.
lipids
What is the clinical significance of measuring fibrinogen levels?
Fibrinogen levels can help assess clotting disorders and the risk of thromboembolic events.
What type of protein is fibrinogen classified as?
A glycoprotein
Multiple Choice: Which protein is crucial for the formation of blood clots? A) Albumin, B) Fibrinogen, C) Globulins
B) Fibrinogen
