Respiration is a series of reactions in which energy is released from glucose glucose: A simple sugar made by the body from food, which is used by cells to make energy in respiration. Aerobic respiration is the form of respiration which uses oxygen.It can be summarised by this equation:glucose + oxygen â carbon dioxide + water (+ energy). Energy is shown in brackets because it is not a substance.Notice that: 1  Glucose and oxygen are used up.erobic respiration is the form of respiration which uses oxygen.

The normal mean corpuscular volume (abbreviated to MCV on full blood count results) is 80-100 fL, with smaller cells (<80 fL) described as microcytic and larger cells (>100 fL) as macrocytic (the latter occur in macrocytic anemia).The MCV is the average red blood cell size.
MCV stands for mean corpuscular volume. Itâs the average volume of the bodyâs red blood cells, measured in femtoliters (one-quadrillionth of a liter). Cell-counting machines calculate MCV from a blood sample.
