The membrane potential of most cells __________. The membrane potential of most cells __________. is determined primarily by sod
IrinaK [193]

Answer:

is negative, except when there is a change in membrane permeability to ions

Explanation:

Membrane potential is voltage that result from differences in Ion concentration of cellular membrane.

Many Ions such as potassium(K+), Sodium(Na+)and chlorine(cl-) has many gradient across the membrane this gives the potential energy. If the membrane is permeable it gives rise to intake of potassium, leading to diffusion of positive charged Ion down the gradient outside the cell leading to a concentration of uncompensated net negative charge.

Hence, the membrane potential is mostly negative except there is a change in members permeability to Ion

Which of the following statements is true? Gram-positive bacteria have a single cell wall anchored to the cell membrane by lipot
Darina [25.2K]

Answer:

Gram-positive bacteria have a single cell wall anchored to the cell membrane by lipoteichoic acid.

Explanation:

According to Gram stain test, bacteria can be divided into two main groups which differs mostly in the structure of the cell wall"

  1. Gram-positive bacteria-thick cell wall which consist of peptidoglycan  layer that is attached to cell membrane via teichoic acids (lipoteichoic acids). Because of their thick wall, after the staining, the violet dye retains, so Gram positive bacteria appear purple-coloured.
  2. Gram-negative bacteria-thin peptidoglycan layer with two cell membranes: inner and outer membrane (lipopolysaccharides). Usually, Gram negative bacteria contain porins. After the staining, the dye does not retain, so this type of bacteria appear red coloured.
