Which of the following do not require enzymes to break them down to smaller units before being absorbed?

There are choices for this question namely:

proteins
starches
disaccharides
monosaccharides

The correct answer is "monosaccharides". Monosaccharides are the most basic form of sugar that can be absorbed in the gastrointestinal tract. When we consume carbohydrates in the form of complex carbohydrates (i.e. starch) it needs to be acted upon by enzymes (initially, amylase) to break it down to smaller dextrans and disaccharides. Disaccharides will be further broken down by disaccharidases in the intestines to monosaccharides for them to be absorbed.

Proteins are acted upon by pancreatic enzymes to break it down to smaller peptides.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

There are many you can go on and ask boring questions about being bored when you’re bored : )
