Which of the following lacks proteins?
Which of the following lacks proteins?
The correct option is C Bile
A.Pancreatic juice – a clear alkaline digestive fluid, contains digestive
enzymes, , including trypsin,chymotrypsin, carboxypeptidase, lipase, and amylase.
B.Saliva - is the
watery and usually somewhat frothy substance produced in the mouths of some
animals, including humans. It contains 98% water, but it contains many
important substances, including electrolytes, mucus, antibacterial compounds
and various enzymes.
C.Bile Bile is synthesised in the liver and stored in the gall
bladder. From gall bladder, bile is released into the duodenum. It
contains bile pigments (bilirubin and biliverdin), bile salts, cholesterol and
phospholipids but no enzymes. The bile secreted is a
yellowish-green fluid that aids in the emulsification of fats. Bile is not an enzyme and it does not contain proteins. (all
most all enzymes are made up of proteins).Hence, bile lacks proteins.
D.Intestinal juice - contains
hormones, digestive enzymes, mucus, substances to neutralize hydrochloric acid
coming from the stomach and erepsin which further digests polypeptides into
amino acids, completing protein digestion.\
So, the correct option is 'bile'.
