Answer:
b. A transferase deficiency will result in an accumulation of the toxic metabolite galactosse 1-phosphate.
c. A galactokinase deficiency will cause an accumulation of galactose.
Explanation:
Transferase is an enzyme which is responsible for the breakdown of galactose which is a known milk sugar. Its deficiency causes the formation of toxic materials such as galactose-1-phosphate which comes from galactose, and galactitol. Galactokinase is also an enzyme which helps in the conversion of galactose into galactose 1-phosphate with the expenditure of ATP molecule, so its deficiency causes the deposition of galactose.
 
        
                    
             
        
        
        
Since the other answer got deleted, i'll just answer it for you.
a sinoatrial node is the main pacemaker that begins each heartbeat located in the junctions of superior vena cava and the right atrium. It signals from the node that spread through the atria and determines the heart rates.
