Accepted Answer

A) True 
 B)False

Question 4

Explain why the discovery of iron-oxidizing phototrophs has important implications for both understanding the evolution of photosynthesis and explaining the large deposits of ferric iron (Fe³⁺) found in ancient sediments on Earth.

Accepted Answer

The sediments containing Fe³⁺ predate th

Accepted Answer

A)  can circumvent substrate-level and oxidative phosphorylation. 
B)  makes insufficient energy to grow but enough for cellular maintenance to survive. 
C)  requires a second bacterium to cooperatively drive the gradient. 
D)  still requires another carbon substrate to provide a carbon source.
