A lab-reared strain of mice is glucose 6-phosphate-insensitive. How would this affect glycogen synthesis? Select the best answer. Glycogen synthesis would increase because a greater insulin concentration would increase glucose transport. Glycogen synthesis would increase because glycogen synthase would always be active. Glycogen synthesis would decrease because the b form of glycogen synthase could not be allosterically activated. Glycogen synthesis would decrease because the usually inactive b form could not be converted to the always‑active a form. Glycogen synthesis would remain unchanged because other regulatory mechanisms would be unmasked.
