Final answer:
The statement that proteins comprise 60-70% of the cell membrane is false Proteins are an integral part of the membrane but only account for about 20-30%. The rest is primarily made up of lipids.
Step-by-step explanation:
The statement 'Proteins make up 60-70% of the cell membrane' is false. A fundamental concept in Biology is the structure of the cell membrane, also known as the plasma membrane. The cell membrane is primarily composed of lipids, specifically phospholipids, and proteins. While proteins are a crucial component of the cell membrane, they typically make up around 20-30% of the membrane, not 60-70%. The remaining majority is mostly made up of lipids.
Proteins embedded in the cell membrane serve various essential functions, such as transport of materials, receiving signals, and acting as enzymes. However, their proportion to the lipids is lesser than the stated figure.
