Though both are unicellular, bacteria doesn’t possess a nucleus or cell organelles, except ribosomes, whereas amoebas possess a well-defined nucleus and all essential cell organelles.
Both bacteria and
amoeba are single-celled organisms. They both have ribosomes.
Bacteria is a
prokaryote. It lacks membrane-bound nucleus, mitochondria, chloroplasts or any
membrane-bound organelles.
Amoeba is a eukaryote.
It has a "true" nucleus containing its DNA and organelles which is
responsible for energy production and protein transport.<span>

Answer:
In muscle cell, fermetation produces <u>"lactate and NAD"</u>
<u>In fermentation Pyruvate is reduced and __NADH__ is oxidized.</u>
Explanation:
Muscle cells perform lactic acid fermentation when enough oxygen is not available to support aerobic cellular respiration. The process of glycolysis forms two molecules of pyruvate from one glucose molecule and uses NAD+ as electron acceptor. During lactic acid fermentation, pyruvate is reduced into lactate and NADH serves as an electron donor. The final products are lactate and NAD+. The reaction is catalyzed by lactate dehydrogenase enzyme. The NAD+ produced by fermentation is required to continue the process of glycolysis.
