The recycling of which compound ensures the continuation of glycolysis under anaerobic conditions?
Mariana [72]


The answer is NAD+.

In the process of glycolysis, NAD+ is reduced to form NADH+ and H+.  If NAD+ is not present, glycolysis will not be able to continue. Under anaerobic conditions, the regeneration of NAD is coupled to the reduction of pyruvate. The anaerobic regeneration of NAD is called fermentation.

In animal tissues , fermentation occurs as  pyruvate acts  as a makeshift hydrogen acceptor and gets  reduced to lactate when NADH transfers electrons to pyruvate. This enzyme catalyzed reaction occurs whenever the available oxygen has been consumed.

The center of our galaxy contains a very intense source of radio and x-ray radiation named sgr a*. what is it about this source
AnnyKZ [126]

The radiation is coming from an incredibly small object. This source supports the idea that the radiation comes from a black hole.

  • The rotating and barycenter of the Milky Way galaxy is known as the Galactic Center (or Galactic Centre).
  • Sagittarius A*, a compact radio source that is almost perfectly at the galactic rotational center, is the galaxy's central massive object and is a supermassive black hole with a mass of roughly 4 million solar masses.
  • Hawking radiation is a result of how quantum fields behave when there is substantial gravity present.
  • Astronomers search for a signal of light from stuff that heats up as it falls into the black hole in order to find this form of radiation, which is only significant for extremely small black holes.
  • SgrA is a radio emission source that is situated in the galaxy's nucleus. Within 1 light year away. , several hundred stars are crowded around it.
