The current theory of the structure of the plasma membrane is best described by?
sandwich
What is a plasma membrane made of?
A plasma membrane is made of a phospolipid bi-layer. Think of a plasma membrane like a grilled cheese sandwich. The bread on the outside of the sandwich is similar to the polar head of the plasma membrane, and the cheese on the inside is similar to the fatty tails on the inside of the membrane. If you tried to run water through the grilled cheese sandwich it would not get through the cheese center, much like water will not get through the center of a plasma membrane.
How does nutrients enter a cell?
The plasma membrane.
What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.
Do plant and animal cells have a plasma membrane?
do animal have a plasma membrane

Turgor pressure is caused by water filling what two things?
Turgor pressure is caused by water filling the plasma membrane and cell wall of plants, bacteria and some fungi. It pushes the plasma membrane against the cell wall to create the pressure.
How does nutrients enter a cell?
The plasma membrane.
Compared to the inside of the resting plasma membrane the outside surface of the membrane is?
The outside is slightly positive while the inside is slightly negative.
Another name for plasma membrane?
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
How is the plasma membrane of the liver cell?

Is a plasma membrane living?
Yes, Plasma membrane is living .
Do animal and plants have a plasma membrane?
do animal have a plasma membrane
What type of membrane is membrane plasma?
The plasma membrane is referred to as a biological membrane or bio-membrane.Briefly, the plasma membrane may also be generally referred to as cell membrane.
What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.
