Facilitated diffusion. It is a passive transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell’s energy supplies. Instead, the energy is provide by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from one side of the membrane to the other. Red blood cells use facilitated diffusion to absorb glucose.

Please vote my answer branliest! Thanks.
The answer TRUE they do not have a fossil record.
Everlasting cells are cells that are incapable of regeneration. these cells are taken into consideration to be terminally differentiated and non-proliferative in postnatal lifestyles. This includes neurons, heart cells, skeletal muscle cells, and pink blood cells.
Pink blood cells (RBCs) fall right into a truly less complicated category. Mature RBCs do not divide. In truth, because mature RBCs do not even have a nucleus, those cells in reality can not do an awful lot of anything other than act as vessels for the hemoglobin with which they are jam-packed. New RBCs are made in the marrow within the mature human.
Because the mitochondria are the mobile website for oxidative metabolism, where glucose is damaged all the way down to carbon dioxide and water to release energy, and because purple blood cells lack these organelles they cannot break down glucose absolutely aerobically.
