Title

Other claims from this paper (7)
- Intervention effect Cu(2+) strongly inhibited uncoupled photosynthetic electron transport in isolated spinach chloroplasts.
- Association Cu(2+) inhibition depended on the ratio of chlorophyll to inhibitor in isolated spinach chloroplasts.
- Observation Binding of Cu(2+) to chloroplast membranes removed Cu(2+) from solution in isolated spinach chloroplasts.
- Intervention effect Preincubation in light increased Cu(2+) inhibition of spinach chloroplasts.
- Intervention effect Preincubation in the dark decreased Cu(2+) inhibition of spinach chloroplasts.
- Association Photosystem I was more resistant to inhibition than photosystem II in spinach chloroplasts.
- Observation The most sensitive site to the inhibitor was the oxidizing side of photosystem II.
