Question

select the correct answer. scientists recently discovered a species of bacteria thats capable of photosynthesis, but its anaerobic and doesnt produce or use oxygen for respiration. which process will be absent in this organism? a. calvin cycle b. electron transport system c. glycolysis d. krebs cycle

Explanation:

The Krebs cycle is an aerobic process that requires oxygen. Since the bacteria are anaerobic and don't use oxygen for respiration, the Krebs cycle will be absent. The Calvin cycle is part of photosynthesis and can occur in anaerobic photosynthetic bacteria. Glycolysis is an anaerobic process and can happen in these bacteria. An electron - transport system can also be present in anaerobic bacteria, although it may use different final electron acceptors.

Answer:

D. Krebs cycle
