“synthesis of one protein cannot take place without the presence of another protein.” is this statement true or false and why?
select one of the options below as your
a.
this statement is false because only dna and rna can carry out protein synthesis, which involves transcription and translation.
b.
this statement is false because protein synthesis can take place directly with the of amino acids.
c.
this statement is true because every step in protein synthesis requires enzymes, which are nothing but proteins.

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.
