17. Write a summary of cellular respiration. In your response:
Cyanobacteria are the evolutionarily oldest organisms with the capability of evolving oxygen, giving rise to the present day atmosphere. These prokaryotic microorganisms have the unique ability to perform oxygenic photosynthesis and respiration in the same cellular compartment. Some cyanobacteria can also fix atmospheric nitrogen alongside oxygenic photosynthesis and respiration. The redox components of these electron transport pathways are known to intersect in cyanobacteria. Majority of the energy‐intensive processes occur in specialised membranes known as thylakoids. The coexistence of such remarkably complex metabolic pathways in a single cyanobacterial cell provides them with the potential to thrive in a wide variety of ecosystems. This metabolic complexity has sparked significant interest towards cyanobacterial research for the production of various high‐value compounds with applications in the food, feed and fuel industry.
What's the difference between Cellular Respiration and Photosynthesis
RO or DI System?
As for what is is better to use, RO or DI, the short answer is if an optimum Reverse Osmosis Filter/Unit is used that utilizes quality TFC (thin film composite) membranes such as the premium Pentair medical grade membrane and activated catalytic carbon block filters, along with a build that properly utilizes the membrane without "flow-by", then the RO unit is more than adequate!
Unfortunately many persons read the "cut and past" hype in many forums, then fall for the cheap price of many Amazon/eBay combined RO/DI units that often cost less than a good quality 3 stage RO unit only.
However when common sense logic is applied, if you are using an RO unit such as the AAP/TMC that applies the features already noted, you will get basically 0 nitrates, 0 phosphates, and 0 chlorine/chloramines and NOT get the concentrated ammonia or other molecules due to high rejection rates and inefficient membranes that then result in your DI resin chamber working over time to removes these! The result is the need to replace these DI resins every 50 gallons of produced water or even less leading to operation cost that far exceed any real or imagined benefit of purchasing these lower cost combined RO/DI filters!!
About all the DI (which means De-ionized) really does for an aquarium keeper over a well designed/quality RO unit is produce a neutral pH water. For marine reef tanks this is unnecessary based on my extensive use and comparison over the years. For a softwater Amazon biotope aquarium, since the KH buffers are stripped by the RO unit, the simple addition of an acid buffer or the natural nitrification bio processes will reduce this pH.
