Which statement could be categorized only in the anaerobic section of the Venn diagram is performed by eukaryotes?
The statement which could be categorized only in the anaerobic section of the Venn diagram is option B) Commercial uses. Option B is undoubtedly the right answer.
Which part of aerobic respiration occurs in the cytoplasm?
What are the major steps in aerobic respiration?
Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.
What is the reaction for aerobic respiration?
Summary. Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).
Do you need oxygen for fermentation?
When oxygen is not present or if an organism is not able to undergo aerobic respiration, pyruvate will undergo a process called fermentation. Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.
Does fermentation need to be airtight?
Does fermentation need to be airtight? No! In fact, primary fermentation should never be airtight because you run the risk of blowing the top off of your fermenter or breaking it completely. As carbon dioxide is created during the fermentation process, an incredible amount of pressure can build up over time.
Can you ferment without an airlock?
No, you do not have to use an airlock. You can successfully ferment many a batch of sauerkraut without one. To reduce air exposure, select a way to hold your ferment below the brine and put a lid on it. To allow CO2 gases to escape, you can use an airlock, or…
What can I use instead of an airlock?
A sanitary piece of aluminum foil crimped over the top or even a plastic baggy with a rubber band on the outside (either use a new roll/box or pour some of your favorite high proof liquor on it just to be sure) should do the trick.
Can I open my fermentation bucket?
It is perfectly fine to open the lid of your fermenter to check the process or take a gravity reading provided that you take the proper precautions to sanitize all equipment used, minimize the amount of oxygen added to your wort, and re-seal the fermentation bucket fairly quickly to avoid contamination.
