Cell Membrane Structure & Function

Front

What is the structure of the cell membrane primarily composed of?

Back

The cell membrane is primarily composed of a phospholipid bilayer.

Front

What are the two main parts of a phospholipid?

Back

The two main parts of a phospholipid are the hydrophilic head and the hydrophobic tail.

Front

What type of proteins are embedded within the cell membrane?

Back

Integral proteins are embedded within the cell membrane.

Front

What is the function of integral (channel) proteins in the cell membrane?

Back

Integral (channel) proteins facilitate the transport of substances across the cell membrane.

Front

What role do carbohydrates play in the cell membrane?

Back

Carbohydrates are involved in cell recognition and signaling.

Front

What is the term for the flexible nature of the cell membrane?

Back

The fluid mosaic model describes the flexible nature of the cell membrane.

Front

What is the function of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the cell membrane's structure and fluidity.

Front

What is the difference between peripheral and integral proteins?

Back

Peripheral proteins are attached to the surface of the membrane, while integral proteins are embedded within the membrane.

Front

What does 'selectively permeable' mean in relation to the cell membrane?

Back

Selectively permeable means that the cell membrane allows certain substances to pass while blocking others.

Front

What is the primary function of the cell membrane?

Back

The primary function of the cell membrane is to protect the cell and regulate what enters and exits.
