Bacteria That Can Not Synthesize All the Necessary Amino Acids

Question

Bacteria that can not synthesize all the necessary amino acids are known as:
A) Prototrophs
B) Auxotrophs
C) Phototrophs
D) Heterotrophs
E) Chemoheterotrophs

Accepted Answer

Auxotrophs are bacterial strains that lack the ability to synthesize all the necessary amino acids for their survival and growth. They are dependent on external sources of these amino acids for growth. Prototrophs, on the other hand, can synthesize all the necessary amino acids, while phototrophs are organisms that can convert light energy into chemical energy. Heterotrophs and chemoheterotrophs are organisms that obtain their energy by consuming organic compounds, but their ability to synthesize amino acids varies.
