Proteins are polymers of hydrocarbons amino acids ch2o units glycerol nucleotides

Hey there! :D

If you ever learned about protein synthesis, you probably have heard about how it is made with amino acids. Messenger RNA (a portion of DNA in the nucleus) is taken to the ribosomes (which make the protein) and the code from the DNA is converted to amino acid sequences, therefore, the polymer and correct answer is amino acid. These amino acids, all combined, become protein chains. I would encourage you to look into the process because it is very interesting and very helpful!

I hope this helps!

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.
