he cell membrane also called as the plasma membrane or plasmalemma is one biological membrane that separates the interior of the cell from the outside environment. The cell membrane surrounds all cells and is selectively permeable, controlling the movement of substances in and out of cells. One of the main functions of the cell membrane is also to take messages from outside the cell (environment) and convey the same to the internal structures of the cell such as nucleus (DNA), mitochondria, etc., so that appropriate responses can be elicited from the cell to these outside stimuli. The cell contains a variety of biological molecules that include proteins, lipids and a variety of enzyme systems that are involved in various cellular processes such as adhesion, ion channel conductance and cell signaling.

Describe how you could simulates one of the cases from the computer simulation (Case 2, Case 3, or Case 4) using the basic labor

satela [25.4K]

In place of clicking on the touchpad for the Cases, I would boost in response to the visual incitements that would be linked with a reflex hammer with an accelerometer; the reflex hammer would move appropriately to the carrying of the picture on the screen by a programmed mechanical device. I wouldn’t use the reflex hammer’s sound however; it’s purely there to compute my reaction times (time of highest acceleration of movement of the reflex hammer deducted by time of reflex) instead of using the computer’s software at figuring reaction times, since I think the software is defective.

What is a cell membrane?

IRISSAK [1]

The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
