Explanation:
(3) active transport
The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.
While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.
Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

If a human’s red blood cells will lack sufficient amount of
hemoglobin, he or she would have also a low amount of oxygen.
Hemoglobin is what makes the red blood cells red in color,
aside from the abnormal color, the red blood cells also make up of oxygen. It can also be with iron since iron is bind
to hemoglobin all the way to the lungs.
