Oxygenic Photosynthesis

Question 1

Oxygenic Photosynthesis

Answer 1

photosynthesis that has O2 as a waste product from tearing apart water

Question 2

How did oxygenic photosynthesis evolve

Answer 2

2 part process:
1- development of oxidant that could remove electrons from water
2- development of enzyme that could transport electrons through the metabolic system

Question 3

theory on how cynobacteria was initially formed

Answer 3

green and purple sulfur shared pigments into one cell, which allowed the 2-step process to occur, in both anoxic and aerobic environments

Question 4

result of oxygen production

Answer 4

aerobic respiration - using external nutrient of O2

Question 5

How many mols of O2 are needed to oxidize 1 mol of glucose

Answer 5

6

Question 6

What microbe do respirating microbes have a syntrophic relationship with?

Answer 6

Cyanobacteria, because they will use the waste products of respiration to replenish the O2
