Apopulation of bacterial cells has been placed in a very nutrient-poor environment with extremely low concentrations of sugars and amino acids. which kind of membrane transport becomes crucial in this environment?

The kind of membrane transport that becomes crucial in an environment when a population of bacterial cells have been placed in a very nutrient-poor environment with extremely low concentrations of sugars and amino acids is the active transport.

Passive transport occurs from a region of higher concentration of the nutrients to a region of lower concentration of nutrients through a semi-permeable membrane. This occurs when bacteria are grown in a nutrient rich media without the involvement of energy.

When bacteria are grown in a nutrient media with low concentration of amino acids and sugars, nutrients have to move from a region of the lower concentration of the nutrients to the region of higher concentration of the nutrients (from nutrient media to the cell). It is against the concentration gradient with the expenditure of energy in the form of adenosine triphosphate (ATP).

cell regulation is conducted by special proteins.
