During bleeding, both formed elements (platelets, white blood cells, red blood cells) and plasma are lost from the circulatory system. They are lost proportionally, so initially there is no change in hematocrit.
Hematocrit is the percentage of the blood volume made up of elements (Hct = cell volume/blood volume). During dehydration, only water and electrolytes are lost, and the number of cells remains constant - the same number of cells in a smaller volume leads to an increase in hematocrit. When the body tries to restore blood volume, the first thing to recirculate is water from the ECF and this increases the amount of water without increasing the amount of red blood cells, so the compensatory mechanism causes the hematocrit to fall.

Best Answer:
ATP synthase makes ATP. found in the inner mitochondrial membrane, it
uses the energy of the proton electrochemical gradient produced by the
electron transport chain to make atp from adp and inorganic phosphate.
the enzyme itself has a passage for protons, and a head which turns. The
head has 3 idential components. passing 10 protons through will turn
the head once. ADP and phosphate can bind to one of the 3 components and
the turning will cause the component to essentially sequeeze the ADP
and phosphate together to make ATP.
