ermentation reactions A. completely oxidize glucose to carbon dioxide and water B. often require the reactions of glycolysis to
goldenfox [79]

Answer:

E. two of the above are correct

Explanation:

Fermentation reactions are processes that occur without the presence of oxygen and promote the release of energy (ATP) anaerobically. For these reactions to occur, glycolysis and reduction of pyruvate must occur.

These reactions allow the regeneration of NAD + that is necessary for the breakdown of glucose during the process called glycolysis, which is primarily responsible for the production of ATP. NAD + is regenerated from NADH.

With that, we can conclude that the correct options are:

B. often require the reactions of glycolysis to provide energy as ATP

C. supply NAD for the oxidation of glucose

tigry1 [53]

Answer: False

Explanation:

Protozoans are not the organism that fix nitrogen for the plants. The organism that fix nitrogen to convert it into a form which can be used by plants are known as diazotrophs.

These are bacteria and archae that fix nitrogen gas found in the atmosphere into more usable form such as ammonia.

These organism can grow without any external source of fixed nitrogen. Example: Rhizobia and azospirillium.

What 3 systems get put to work when a beaver is building a home and how?
Lisa [10]

Answer:

beaver dams smooth out water flow by increasing the area wetted by the stream. This allows more water to seep into the ground where its flow is slowed. This water eventually finds its way back to the stream. Rivers with beaver dams in their head waters have lower high water and higher low water levels.
