a.
b.
c.
d.
e.
The main function of cellular respiration is
breaking down toxic molecules
making ATP the powers cell activities

cellular respiration
a. CO2 ......H2O
b. O2......glucose
c. H2O......ATP
d. glucose ......CO2
e. ATP.......O2

7. Unlike turkey breast, the breast of duck is “dark meat.” Why?
a. ducks fly longer distances, so their breast muscles consist of fast fibers
b. ducks fly faster then turkeys, so duck breast muscles consist of fast fibers
c. c. the fibers of dick breast muscles contain less myoglobin
d. ducks fly longer distances , so their breast muscles contain more slow fibers
e. duck muscles fibers are specialized for anaerobic ATP production
