Answer:
The blood group A antigen is synthesized by an N-acetylgalactosaminyltransferase that uses a UDP-α-N-acetylgalactosamine (UDP-GalNAc) as sugar donor substrate, while the B antigen is synthesized by a galactosyltransferase that uses a UDP-α-galactose (UDP-Gal) as a sugar donor substrate.
The substrate for A antigen is N-acetylgalactosaminyltransferase which uses a UDP-α-N-acetylgalactosamine (UDP-GalNAc) as sugar donor substrate and the substrate for B Antigen is galactosyltransferase which uses a UDP-α-galactose (UDP-Gal) as a sugar donor substrate.
What are Antigens?
Antigen is any substance which is recognized as foreign particle by the immune system. It is also known as Immunogens. It triggers the Immune system. Antigens can be endogenous, exogenous or autoantigens. Some examples of antigens are pollen, bacteria, viruses, etc.
There are three types of antigens which includes
1. Exogenous antigen - It is foreign to the immune system
2. Endogenous antigen- It is produced by intracellular bacteria and virus which replicates inside the host cell.
3. Autoantigens- It is produced by the host.
Antigen-presenting cells help the immune system triggers its attack. There are three types of antigen-presenting cells in your body. They are
1. Macrophages
2. Dendritic cells
3. B cells
Thus, the substrate for A antigen is N-acetylgalactosaminyltransferase which uses a UDP-α-N-acetylgalactosamine (UDP-GalNAc) as sugar donor substrate and the substrate for B Antigen is galactosyltransferase which uses a UDP-α-galactose (UDP-Gal) as a sugar donor substrate.

What is polyhydroxyl alcohol?The condition whenever we have several[tex]C-OH[/tex] bonds, we have a polyhydroxyl alcohol. For example, if we have just one alcohol group, that is, an [tex]R-OH[/tex] group, then the naming is simple, say, we have [tex]EtOH,[/tex]it's ethanol.
The glucose and ethanol similar in structure and function as the ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products.
When the aldehyde ethanal begins to form which will be evident by the change in the colour of solution from orange to green, then the mixture should be distilled from the test tube and tbethe aldehyde collevted so that it doesn't undergo additional oxidation into ethanoic acid.
Therefore, The statements that best describes the alcohol is that it is only legal for people age 21 and older and it is always legal to use alcohol. Thus, option B and C are correct.
