Chemoheterotrophs
|
|
|
Oxygen molecules with high energy electrons that arise during photosynthesis. Carotenoids help remove excess energy.
|
Singlet Oxygen
|
|
|
Form during incomplete reduction of oxygen during metabolsm. Superoxide dismutases detoxify them.
|
Superoxide radicals
|
|
|
Formed during rxns catalized by superoxide dismutase. Use enzymes CATALASE or PEROXIDASE to detoxify
|
