Glucose can move into cells by active or passive transport, in both cases membrane-spanning proteins are required. Active transport (SGLT) uses the concentration gradient of Sodium ions to move glucose against its concentration gradient. Passive transporters (GLUT) are only effective if the concentration of glucose in the cell is lower than outside the cell.
The glucose goes in through the membrane and can in or out either ways.
Glucose molecules are moved into a cell via a transport protein called a glucose transporter. This process is facilitated diffusion, a type of passive transport that does not require energy. Glucose transporters help move glucose across the cell membrane down its concentration gradient.
glucose molecules will diffuse out of the cell. apex

Water will move out of the cell. Glucose will not move into the cell without the help of a helper molecule. Glucose molecules will diffuse into the cell.(APEX)
Glucose is too big to pass throught.
Glucose is too big to pass throught.
Glucose is too big to pass through.
The cell solves this problem by using transport proteins called glucose transporters. These transporters serve as gateways in the cell membrane, allowing glucose molecules to pass through into the cell. This process is facilitated by protein channels that specifically recognize and transport glucose molecules.
Carrier molecules have specific binding sites that are complementary to the structure of glucose molecules. This allows the carrier molecules to selectively recognize and transport glucose across the cell membrane while excluding other sugars. The specificity of recognition is determined by the shape, size, and chemical properties of both the carrier molecule and the glucose molecule.
Compared to other more basic molecules, glucose is rather large. In order for glucose to enter the cell in the first place, the cell must actively transport it from outside the cell wall using special transport proteins. This is compared to a cell passively transporting molecules, where the molecules are small enough (or non polar) to pass through the cell membrane without any action from the cell itself.Once the glucose is in the cell, there is no way to get out.
Passive diffusion is a method by which glucose molecules enter cells. Glucose can diffuse through the cell membrane down its concentration gradient without the need for energy input from the cell.
