1. Glucose enters the cell by simple diffusion across the membrane. The addition of a bulky polar group like phosphate prevents it from diffusing right back out.
2. This is the first phosphate group that will contribute to the formation of glyceraldehyde-3-phosphate (GAP), an important intermediate in glycolysis.

Does glucose enter or leave a cell?
Glucose enters a cell through facilitated diffusion using glucose transporters on the cell membrane. Once inside the cell, glucose is used in cellular respiration to produce energy.
What type of diffusion helps glucose enter the cell?
facilitated diffusion
What are the only materials that can enter the cell?
Oxygen, amino acid and glucose.
In order for a cell to obtain glucose in a culture he concentration of glucose must be?
In order for a cell to obtain glucose in a culture, the concentration of glucose must be higher outside the cell than inside. This concentration gradient allows for passive transport mechanisms, such as facilitated diffusion, to occur, enabling glucose to enter the cell. If the external glucose concentration is too low, the cell may struggle to uptake sufficient glucose for energy and metabolism. Therefore, maintaining an adequate glucose concentration in the culture medium is crucial for optimal cell growth and function.
What is a passive method by which glucose molecules enter cells?
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.

How can a cell speed up its intake of glucose from the environment?
A cell can speed up its intake of glucose from the environment by increasing the number of glucose transporters on its cell membrane. This allows more glucose molecules to enter the cell at a faster rate. Additionally, the cell can increase its energy consumption to create a higher demand for glucose, driving the need for faster uptake.
Why do glucose need insulin to enter cells?
Most cell membranes are NOT permeable to sugar unless insulin opens a channel.
How do we get the glucose we need to power our cell?

How does insulin help glucose enter your blood cells?
Insulin helps glucose enter your blood cells by binding to insulin receptors on the cell membrane, which triggers a series of chemical reactions inside the cell that allow glucose to be transported from the bloodstream into the cell for energy production.

How can a cell that consumes glucose speed up its intake of glucose from the environment?
A cell can speed up its intake of glucose by increasing the number of glucose transporters on its membrane. This allows more glucose molecules to enter the cell in a shorter amount of time, facilitating faster uptake. Additionally, cells can also activate signaling pathways to enhance the activity of existing glucose transporters, further increasing the rate of glucose uptake.
