Why are some tissues more vulnerable to inhibition of PDC activity, and how does this selective tissue vulnerability explain the cardinal clinical manifestations of the disease?

Some tissues are more vulnerable to PDC deficiency as they have high demand of oxygen and ATP like brain cells or neurons and muscles. Due it's deficiency both oxygen and ATP demand is not fulfilled and these cells show signs earlier then other cells

voluntary muscles are controlled by the cerebellum.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
