(Respiration) What is the purpose of respiration?
- release energy in glucose to make ATP
- the ATP gives the cell the power to do work
(Respiration) Is respiration 100% effective?
No (only about 40%)
(Respiration) If not all the energy from our food is stored in ATP, what happens to the rest of it?
gets hot and comes off as heat
(Respiration) What is the equation for respiration?
C6H1206+6O2----->6CO2+6H2O+ATP
(Respiration) What is the equation for photosynthesis?
6CO2+6H2O------>C6H12O6+6O2
(Respiration) In respiration, how many molecules of O2 are used to break down one molecule of glucose?
12
(Respiration) How many molecules of CO2 and H20 are produced?
6
(Respiration) What is the total number of ATP that can be formed from one molecule of glucose?
34-38
(Respiration) What are the 3 stages of respiration?
1.) glycolysis
2.) the Krebs Cycle
3.) the electron transport chain
(Respiration) What are aerobic and anaerobic?
- AEROBIC: the Krebs Cycle and the electron transport chain
- ANAEROBIC: glycolysis
(Glycolysis) What does it split in half?
glucose
(Glycolysis) Into 2 molecules of...?
pyruvate
(Gylcolysis) How many C atoms are in a glucose molecule?
6
(Glycolysis) How many C atoms in each pyruvic avid molecule?
3
(Glycolysis) Aerobic or anaerobic?
anaerobic
(Glycolysis) How many ATP molecules are required?
2
(Glycolysis) How many ATP molecules are produced?
2
(Glycolysis) How many NADH molecules are produced?
2
(Intermediate Step) What are the pyruvic acid molecules converted into as they move into the mitochondrion?
acetyl CoA
(Krebs Cycle) Where does it take place inside the mitochondrion?
matrix (jelly-like substance inside the mitochondria)
(Krebs Cycle) Does it require oxygen?
yes
(Krebs Cycle) What goes around the cycle?
each molecule of acetyl CoA
(Krebs Cycle) How much ATP, CO2, FADH2, and NADH are made?
ATP - 2
CO2 - 4
FADH2 - 2
NADH - 6
(Electron Transport Chain) Where does it take place in the mitochondrion?
inner mitochondrial membrane
(Electron Transport Chain) What do the FADH2 and NADH molecules provide to the chain?
electrons
(Electron Transport Chain) What atoms are removed?
hydrogen atoms
(Electron Transport Chain) What do they make after joining with oxygen atoms?
H20
(Electron Transport Chain) What happens to the electrons?
they are bounced from one molecule to another
(Electron Transport Chain) What are the electrons giving up as they go down?
their energy
(Electron Transport Chain) What is this energy used for?
to attach phosphate molecules to ADP molecules, making ATP
(Electron Transport Chain) What happens to the water?
it gets released
(Electron Transport Chain) How many ATP molecules are produced?
32 or 34
Is a process that requires oxygen called aerobic or anaerobic?
aerobic
Which substances are required for cellular respiration to occur?
oxygen and glucose
Which substances are produced by cellular respiration?
ATP, H20, carbon dioxide
Where do the glucose and oxygen required for respiration come from?
- glucose - food
- air - breathe it in
- plants make both of them
How many carbon atoms are in one molecule of glucose?
6
How many ATP are used in glycolysis?
2
How many ATP are produced?
4
Where in the cell does glycolysis occur?
cytoplasm

What are the other two compounds formed, that store high energy electrons?
NADH and FADH2
What happens to the FADH2 and the NADH, after they release the high energy electrons and the H+ ions?
they get recycled
What is the energy from the high energy electrons used for?
to make ATP (change ADP to ATP)
