Section 1 (Pgs 131-136)
1.) What is cellular respiration?
2.) The first stage of cellular respiration is _______________ and during this part glucose breaks
down into 2 ________________ while producing _____ ATP’s.
3.) If there is no oxygen present then ____________________ or ________________
_______________ occurs during the second stage of cell respiration.
4.) Why is this stage important if it makes no ATP for the organism?
5.) We discussed two forms of fermentation. What are they and in what ways do humans use them to
produce food or drink products?
1.)
2.)
6.) Why do your muscles start to ache after working them for long periods of time?
7.) Why can smaller organisms live in an oxygen-absent environment when larger organisms cannot?
Section 2 (Pgs 137-144)
