CO_2-inhibition of the amplitude of bending of triton-demembranated sea urchin sperm flagella [PDF]
, 1977 Demembranated sea urchin spermatozoa were reactivated in solutions containing KHCO_3 and observed in a covered well slide. Although KHCO_3 itself causes a small inhibition of flagellar beat frequency, the results confirm previous observations of a direct
