CH9 Respiration Flashcards
1
Q
Cellular respiration
A
process where living cells obtain energy from organic molecules
2
Q
Aerobic / Anaerobic Respiration
A
With/ without oxygen
greater ATP yield w/ O2
3
Q
Glucose Metabolism Net Reaction
A
C6H1206 + 6O2 —-> 6 CO2 + 6 H20
4
Q
GLYCOLYSIS
A
- Occurs in Cytoplasm
- Universal process
- Starts w/ Glucose, ends w/ Pyruvate
5
Q
Citric Acid (Krebs) Cycle
A
- Mitochondria
- breaks down Pyruvate —> acetyl group
- Acetyl group oxidized —> 2CO2
- Yield is MANY NADH electron carriers
6
Q
Oxidative Phosphorylation #1
A
- NADH Electrons transferred to ETC
7
Q
Ox. Phos. #2
A
- ETC transports H+ from matrix to inner membrane creating electrochemical gradient (proton motor force)
8
Q
Ox. Phos #3
A
H+ returns to matrix by way of membrane channel (ATP Synthase) ATP Molecules formed
Chemiosmosis
9
Q
Glycolysis Net Yield
A
2 ATP & 2 NADH
10
Q
Citric Acid Cycle Net Yield
per Glucose
A
- 4 CO2
- 2 ATP
- 6 NADH
- 2 FADH2
11
Q
ETC Location
A
Mitochondria matrix membrane
12
Q
Low energy electrons
A
FADH
13
Q
High energy electrons
A
NADH
14
Q
ATP Synthase
A
channel protein facilitating Phosphorylation
15
Q
Ox. Phos RXN
A
4H+ + 4e- +O2 = 2 H2O
