What does Dr. Green find? (Select all options that apply)

(a) Glutamate secretion decreases after addition of the K⁺ channel blocker

(b) The membrane of rods depolarizes after addition of the K⁺ channel blocker

(c) Serotonin secretion increases after addition of the K⁺ channel blocker

(d) Action potentials are generated in rods after addition of the K⁺ channel blocker

(e) cGMP secretion increases after addition of the K⁺ channel blocker
