. The Vmax of a glucose transport into a certain preparation of red blood cells is determined to be 1206nmol glucose/s without ATP present in the buffer. The Vmax of a glucose transport into the same preparation of red blood cells is determined to be 1158nmol/s when ATP is present in the buffer. However, when cells that do not express any glucose transporter are probed for rate of glucose transport, Vmax is infinite. Explain these data.

During a process of facilitated diffusion, presence ATP increase the rate of glucose transport through a protein membrane of a red blood cells. Vmax will then be on increased.

Explanation:

The rate of glucose transport in to the certain sample of blood is a facilitated diffusion process. It is understandable to be on increase through a protein membrane with the presence of enzyme to speed up the rate of the biological reaction. This is reflected when it was initially observed that with the enzyme ATP presence in the buffer, the Vmax of a glucose transport into the certain preparation of red blood cells is determined to be 1206nmol glucose/s(considerably low).

When ATP is added, the Vmax is on increase. That is, the Vmax of a glucose transport into the same preparation of red blood cells is determined to be 1158nmol/s. Then Vmax rises to infinity, when cells that do not express any glucose transporter are probed for rate of glucose transport.

It can be further explained that glucose moves into the blood through the permease in the membrane between the cell and the blood.Thus, ATP is used as an energy source to drive Na+ out of the cell, resulting in glucose transport from the intestine to the blood.

Membrane proteins must have an asynchronous distribution on the cell membrane for the system to function. This is an example of the membrane synthetic apparatus determining where in a membrane a protein should be localized. The Na+K+ ATPase must be localized to the membrane between the cell and our blood.
