Why Is the T State of Glycogen Phosphorylase Less Active

question 1

Multiple Choice

Why is the T state of glycogen phosphorylase less active?

• A) The adjacent amino acids are not phosphorylated, and thus the catalysis cannot be carried out.
• B) The active site is partially blocked.
• C) ATP cannot be bound by the T state.
• D) Glucose-1-phosphate remains bound to the active site.
• E) None of the answers is correct.

Definitions:

Circular Runout

A term in mechanical engineering that describes the tolerance of how much one circular element of a part can deviate from a perfect circle as it rotates.

Cross Section

A diagram or representation showing the internal structure of something when cut along an imaginary line.

Circular Runout

A tolerance that limits the total variation a surface can have when rotated around a central axis, ensuring roundness and smooth operation of rotating parts.

Total Runout

A composite tolerance applied to a feature which controls both its form and its orientation to a datum axis.
