What is a star like object that is very bright and distant

Quasar is a star like object that is very bright and distant.

Quasars are massive, bright, and most distant known celestial objects that release high amounts of energy in the form of electromagnetic radiation, which usually has a star-like image in a telescope. Quasars can only be found in galaxies that have super-massive black holes (black holes that have billions of times of solar masses). In quasars, the black holes are enclosed by a gaseous accretion disk.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
