Sugars on the external side of the cell membrane play a crucial role in cell recognition and communication. They are involved in the formation of glycoproteins and glycolipids, which facilitate interactions between cells and their environment, including signaling pathways and immune responses. Additionally, these sugars contribute to the protection of cells by forming a glycocalyx, which can provide a barrier against pathogens and help maintain cell integrity. Overall, they are vital for maintaining cellular function and homeostasis.
Membrane digestion refers to the process by which cells incorporate nutrients from the external environment through the cell membrane. This process involves the uptake, processing, and absorption of nutrients such as amino acids, sugars, and lipids by the cell. Membrane digestion plays a crucial role in nutrient acquisition and energy production for the cell.
Glycoproteins are membrane proteins that have sugars attached to themselves. These sugars play a role in cell recognition by helping cells identify "self" molecules from non-self molecules.

The cell membrane is somewhat of an environment.. cell membranes have many proteins inside them.. the proteins regulate the cell structure, allow cell-cell interaction, and allow passage of materials through the membrane. There also steroids in the membrane that regulate its shape.. and there are also various sugars / glycoproteins in the membrane. Also, one important thing to realize is that the inside of the cell membrane is NON polar.. the outside is polar however.

The plasma membrane is the bi-layer of phospholipids the encompass the cell. It is made of phospholipids, protiens, and sugars.
Glycoproteins are membrane proteins that have sugars attached to themselves. These sugars play a role in cell recognition by helping cells identify "self" molecules from non-self molecules.
It is called the cell membrane. This is in Plant and animal cells, although the plant cell has the cellulose wall as well. The cell membrane is semi permeable. Water molecules can pass easily through it through a process call osmosis (the diffusion of water molecules).
Phospholipid bilayer and embedded proteins and sugars
Passive transport.
They allow movement of salts and sugars through the plasma membrane

If a membrane is permeable to a substance, it means that there are gaps/holes/pores in the membrane large enough for that substance to pass through. Starch molecules are bigger that sugar molecules. So if the membrane is not permeable to sugars, the gaps/holes/pores will not be big enough for starch molecules to pass through either.
The difference between intrinsic and extrinsic sugars is that intrinsic sugars are sugars that occur naturally in the cellular structure of food while extrinsic sugars are added or are free in food. Intrinsic sugars are mostly found in fruits and vegetables. Extrinsic sugars are divided into milk sugars or lactose and non milk extrinsic sugars which are added sugar and honey. - Intrinsic motivation is your own personal motivation that comes from inside you. It is self motivation personal gain, satisfaction, or enjoyment. Extrinsic motivation is from external sources, money, coercion, fame, fortune, recognition. - Extrinsic is external; intrinsic is internal Intrinsic is inner or from inside and extrinsic is outer or from outside
