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.

Cerebellum. This area of the brain is the back.

<h3>The brain's mechanism for detecting touch?</h3>

Sensitivity to touch and cortical maps

Initial impulses from sensations are produced by touch receptors in your skin. They move along sensory nerves made of bundled fibers that are linked to spinal cord neurons. After that, information is transmitted to the thalamus, which in turn informs the rest of the brain.
