Unformatted text preview: carbon can go to biomass rather than any of it be oxidized in a mechanism to produce ATP. However, if reduced carbon is not available, the metabolic mode of photoautotroph is no more competitive than an organoheterotroph. Conversely, many photoheterotrophs can also grow as a photoautotroph. Thus, in the absence of organic carbon, a phototroph could grow using CO 2 as the carbon source as an autotroph, providing a suitable electron donor is present in the environment to reduce the oxidized reaction center....
