Describe gas exchange during external respiration and internal
respiration, including how the partial pressure gradients determine
the diffusion of the gases.
This is the general
equation for cellular respiration: C6H12O6 + 6 O2 ? 6 CO2 + 6 H2O +
Energy. Carbon dioxide (CO2) is released during which of the
following stages of cellular respiration? (choose all that
apply)
citric acid cycle
oxidative
phosphorylation
glycolysis
pyruvate oxidation
Cellular respiration requires O2 as one reactant and
creates CO2 as one of the products.
A. Explain how partial pressure
differences between the cell and the capillary result in the
movement of those gases between the cell and the capillary.
B. Explain how CO2 and
O2 are carried in the blood (i.e. where in the blood is
most of the CO2? Where in the blood is most of the
O2?)
C. Deoxygenated blood leaves the
capillary on the venule end...
Internal respiration refers to the exchange of gases between the
blood in ____________ capillaries and the tissue fluid. Internal
respiration services tissue cells, and without internal
respiration, cells could not continue to produce the ____________
that they need as an energy source. Blood in the systemic
capillaries is a ____________ color because of the presence of
oxyhemoglobin. Oxyhemoglobin gives up ____________ , which diffuses
out of the blood into the tissues. Oxygen diffuses out of the blood
into the tissues...
