Describe how glucose molecules enter a cell by facilitated diffusion?
protein
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.
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.
Does glucose enter cells through cell membrane or mitochondria?
Glucose is diffused through facilitated diffusion in the cell membrane. It is oxidised by glycolysis in the cytoplasm and then the products either go through the mitochondria if oxygen is present or goes through fermentation in the cytosoplasm if no oxygen.
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called facilitated diffusion. In this process, carrier proteins aid in the movement of glucose across the membrane down its concentration gradient.

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.
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.
Does glucose enters a cell most rapidly by facilitated diffusion?
No, glucose enters a cell most rapidly through facilitated diffusion with the help of glucose transporters, such as GLUT proteins. Facilitated diffusion allows glucose to move down its concentration gradient into the cell without requiring energy.
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 are diffusion and facilitated diffusion similar?
Substances enter a cell through the cell membrane
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.
What can enter a cell by diffusion?
a gas?
What mechanism by which glucose can enter the cytoplasm without expending ATP is?
Facilitated diffusion is the mechanism by which glucose can enter the cytoplasm without expending ATP. This process uses specific membrane proteins called glucose transporters to facilitate the movement of glucose down its concentration gradient into 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.
Identify at least five ways by which a substance may enter the cell?
A substance can enter a cell through diffusion, facilitated diffusion, active transport, endocytosis, or passive transport. Each of these processes has different mechanisms for moving substances across the cell membrane.
Give example of facilitated diffusion?
An example of facilitated diffusion is the movement of glucose into a cell with the help of glucose transport proteins embedded in the cell membrane. These transport proteins provide a channel for glucose molecules to pass through the membrane, following the concentration gradient from higher to lower concentration without requiring energy input.
