OVERVIEW
1) In which organelle does cellular respiration occur?
2) Can bacteria perform aerobic respiration?
3) Aerobic respiration means respiration in the presence of:
4) TRUE or FALSE. (circle one) Plants do NOT do cellular respiration.
5) Fill in the missing parts of the cellular respiration equation below:
+
6O2

+ 6H2O
+
6) What are the 3 steps in Cellular Respiration:
1)
2)
3)
GLYCOLYSIS
7) What is glucose broken down into during glycolysis?
8) How many ATPs do we get from breaking glucose in half?
9) What molecule (electron carrier) is made that contains a lot of high energy electrons?
KREB’S CYCLE
10) How many ATPs are produced? _________
11) What are the 2 high energy electron carriers also produced in this step?
and
ELECTRON TRANSPORT CHAIN
12) What is a by-product of the electron transport chain? ______________
13) How much ATP can be produced with oxygen present?
14) The electrons from FADH2 and NADH are pumping
the inner mitochondrial space.
through proteins into
.
15) All of the protons that are in the inner mitochondrial
space have no place to go, therefore, they are forced to go
through a protein called ATP synthase which is the site for
(energy production).
ANAEROBIC PROBLEM
16) Since there is no oxygen present, what molecule is no
longer available to receive the electrons from breaking the
glucose?
17) The first solution to the anaerobic problem is lactic acid fermentation. What type of cell does this
occur in?
18) What molecule are the pyruvates being converted into during lactic acid fermentation?
19) How many ATP are being made during this process?
20) The second solution to the anaerobic problem is the process called
21) What molecule are the pyruvates being converted into during alcoholic fermentation?
22) What is another product (gas) of alcoholic fermentation?
