Which enzymes are needed to produce recombinant plasmids to be used in gene transfer?
a. dna polymerase and dna ligase
b. dna polymerase and restriction enzyme (endonuclease)
c. transcriptase and rna polymerase
d. restriction enzyme (endonuclease) and dna ligase

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.

this is a good question! i'll do some research and come back when i have the answer!
