Why does the presence of alpha – fetoprotein interfere with the result of protein analysis by electrophoresis in a pregnant woman?

It causes coagulation factors to form in the electrophoretic pattern

It creates undesirable wave (band) between beta and gamma globulin bands in the electrophoretic pattern (correct)

It leads to an inaccurate measurement of albumin levels

It reduces the overall protein concentration in the blood sample

Why is it difficult for humans to absorb cellulose?

Cellulose has a complex molecular structure that prevents absorption in the human digestive system

Cellulose contains high levels of phosphorus, which competes with calcium absorption

Cellulose consists of repeating units of glucose bound together by beta-linkages, which humans cannot break down due to absence of the necessary enzyme (correct)

Cellulose is a polysaccharide that interferes with the absorption of essential vitamins

What is the main function of lipase secreted by the pancreas?

Hydrolyze proteins into amino acids

Emulsify dietary fats for better absorption

Convert triglycerides into cholesterol

Break down lipids into fatty acids and glycerol (correct)

Why is serum used instead of plasma in electrophoresis?

Plasma contains coagulation factors such as fibrinogen, which interfere with the electrophoretic pattern Signup and view all the answers

Why does cola decrease the absorption of Ca+2?

Cola contains high amount of phosphorus (Phosphoric acid) that competes with Ca+2 and reduces its absorption. Signup and view all the answers

Why is it difficult to test the blood of a pregnant woman by electrophoresis?
