Question

What chemical substances compose the plasma membrane?

Answer 1

Explanation:

Phospholipids are a principle component of plasma membranes, so they would occupy the larger half of 100%.

I would estimate around 90% are phospholipids, but I am not 100% sure.

_______________________

Phospholipids are amphipathic molecules that are regularly organized in the membrane according to their polarity: two layers of phospholipids form the lipid bilayer with the polar part of the phospholipids pointing to the exterior part of the layer and the non-polar phospholipid chains toward the interior.

Proteins can be found embedded in the lipid bilayer.

Answer 2

Phospholipids, proteins, and carbohydrates are the chemical substances that compose the plasma membrane

Explanation:

• Phospholipids, proteins, as well as carbohydrates, are the primary components of the plasma membrane. Phospholipids, amphipathic molecules, are consistently structured in the membrane based on their polarity
• Two layers of phospholipids create the lipid bilayer, with the polar half of the phospholipids facing the layer's exterior as well as the non-polar phospholipid chains on the inside.
• Proteins can be mainly found in the lipid bilayer, and certain carbohydrates are attached to proteins and phospholipids on the membrane's external surface.
