The effects of Cu on the adenylate energy charge of open ocean phytoplankton

The effects of short-term, acute Cu exposure (6 h) on the adenylate energy charge (ECA) of open-ocean phytoplankton populations (northeastern equatorial Pacific) were investigated. Energy charge remained at ˜0.77 over the range of Cu additions (0.025 − 5.μg l−1), even though 14C uptake and total ade...

Description
Summary:The effects of short-term, acute Cu exposure (6 h) on the adenylate energy charge (ECA) of open-ocean phytoplankton populations (northeastern equatorial Pacific) were investigated. Energy charge remained at ˜0.77 over the range of Cu additions (0.025 − 5.μg l−1), even though 14C uptake and total adenylate levels (ATP + ADP + AMP) were reduced by as much as 60%. These findings suggest that ECA alone is not a sensitive indicator of acute sublethal metal effects on phytoplankton.
