Where Is The Higher Concentration Of Glucose?

by | Last updated on January 24, 2024

, , , ,

The glucose molecules in

the intestine

might be in a higher concentration than in the intestinal cells and blood – for instance, after a sugary meal. At this point it will diffuse from high concentration in the intestine to a lower concentration in the blood.

Is there a higher concentration of glucose inside or outside the cell?

Most cells, including erythrocytes, are exposed to extracellular glucose concentrations that are

higher than those inside the cell

, so facilitated diffusion results in the net inward transport of glucose.

Is the concentration of glucose higher in the blood or small intestine?

There is more glucose (a

higher concentration

of glucose) in the intestine than the blood after having just eaten a sugary meal. So, the glucose moves from high concentration in the small intestine to lower concentration in the blood by diffusion.

Which side has the higher concentration of glucose quizlet?

A beaker is divided by a selectively permeable membrane. Initially there is a higher concentration of glucose on the

left side

of the membrane.

Does glucose move from high to low concentration?

It occurs down a concentration gradient – molecules move from an

area of high to lower concentration

. This does not require a supply of energy because diffusion is a spontaneous process. … Glucose diffuses from the blood into the cytoplasm of liver cells via a transport protein called GLUT4.

What will happen if the concentration of glucose in the cell increase?

If the blood glucose concentration rises too high then

cells can lose water

. This may interfere with cell activities. If the blood glucose concentration falls too much then body cells will not receive as much glucose and so will not be able to release so much energy in respiration.

What prevents glucose from leaving the cell?

Glycolysis: Definition, Steps, Products & Reactants

This results in a net negative charge on what has then become a

glucose-6-phosphate molecule

, which prevents it from leaving the cell.

What organ monitors the concentration of glucose in the blood?


The pancreas

continually monitors the level of glucose in the blood.

How glucose is absorbed into the bloodstream?

Absorption of glucose entails

transport from the intestinal lumen

, across the epithelium and into blood. The transporter that carries glucose and galactose into the enterocyte is the sodium-dependent hexose transporter, known more formally as SGLUT-1.

How does the concentration of glucose change in the small intestine?

The glucose molecules in the intestine might be in a higher concentration than in the intestinal cells and blood – for instance, after a sugary meal. At this point it will

diffuse from high concentration in the intestine

to a lower concentration in the blood. This doesn’t require energy.

Which solution has a higher concentration of glucose?

If the concentration of glucose in the water outside of a cell is higher than the concentration inside, the solution is said to be

hypertonic

. As we know, glucose is a molecule that can move across the cell membrane.

Which way will the glucose move?

Glucose tends to move from an

area of high concentration to an area of low concentration

, a process called diffusion. Because the glucose transporter works with the concentration gradient, its process of moving glucose across the cell membrane is called facilitated diffusion.

Why does glucose continues to enter a cell?

ATP.

The concentration of glucose inside of a cell is higher than the concentration outside of that cell

, yet glucose continues to enter the cell. … The concentration of glucose inside of a cell is higher than the concentration outside of that cell, yet glucose continues to enter the cell.

Does glucose move in or out of the cell?


Glucose cannot move across a cell membrane

via simple diffusion because it is simple large and is directly rejected by the hydrophobic tails. Instead it passes across via facilitated diffusion which involves molecules moving through the membrane by passing through channel proteins.

What moves from low to high concentration?

Explanation: The process by which particles move from low concentration to high concentration is called

active transport

and it is against the concentration gradient.

How does glucose move from the bloodstream into the cell?

Glucose is a six-carbon sugar that is directly metabolized by cells to provide energy. … A glucose molecule is too large to pass through a cell membrane via simple diffusion. Instead, cells assist glucose diffusion through

facilitated diffusion

and two types of active transport.
