The major function of alpha and beta globulins in the plasma is

  1. They develop colloidal osmotic pressure

  2. Help in immune response

  3. Act as antigens

  4. Act as carrier proteins
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Alpha and beta globulins function as enzymes and proteins that transport compounds in the body. Gamma globulins act as the antibody defence against antigen invasion. Beta globulins are also manufactured mostly in the liver. 

So the correct option is 'Act as carrier proteins'.

Multiple choice zoology endocrine system and chemical co-ordination gastrointestinal tract and liver hormones of heart, kidney, liver and gastrointestinal tract coordination in human beings- chemical control

The function of enterogastrone hormone is

  1. To control excretion

  2. To inhibit gastric juice secretion

  3. Regulate the absorption of food

  4. To stimulate gastric glands to release gastric juice
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Enterogastrone is a hormone secreted by the duodenal mucosa, when fatty food is in the stomach or small intestine; it is also released, when sugars and proteins are in the intestine. Enterogastrone is transported by the bloodstream to the glands and muscles of the stomach, where it inhibits gastric movements and secretions, by blocking the production or activity of gastrin.
