Aerobic Respiration

Question 1

Catabolism

Answer 1

Getting usable energy (usually ATP)
Getting electrons
Cellular respiration and Fermentation

Question 2

Chemoorganotrophic fueling processes

Answer 2

Aerobic vs Anaerobic
breaking down glucose
Requires +generates energy

Question 3

Glycolysis pathways

Answer 3

Embden-Meyerhof-Parnas (EMP)
Entner-Doudoroff (ED)
Pentose Phosphate (PP)

Question 4

Steps of aerobic respiration of glucose

Answer 4

Glycolysis (Embden-Meyerhof-Parnas pathway)
Citric acid cycle (Kreb’s cycle)
Electron transport chain +oxidative phosphorylation

Question 5

EMP

Answer 5

Requires ATP
6 C glucose (phosphate group 2*3C pyruvate
Make ATP by SLP, Make NADH

Question 6

ED

Answer 6

1 ATP in,2 ATP out-Net 1 ATP
Glucose to 2 pyruvates
1NADH +1 NADPH

Question 7

Kreb’s cycle=TCA cycle

Answer 7

2 3C pyruvate into 61C CO2
1 ATP by SLP
goes around twice
8NADH,2FADH

Question 7

PP

Answer 7

Glucose to carbon skeleton-anabolism
Net-1ATP 2NADPH
Goal:carbon skeletons+ e- for anabolism

Question 8

ETC

Answer 8

PMF=ATP synthases
Electrons from glucose, NADH +FADH2
E- move down electron chain-protons pumped out
oxygen is final e acceptor -reduced to water

Question 9

Complex 1

Answer 9

First step in ETC
NADH to complex 1 to complex 3 by Q
Four H+ pumped out

Question 10

Complex 2

Answer 10

FADH2 to complex 2 to coenzyme Q to Complex 3
zero H+ pumped out

Question 11

Complex 3

Answer 11

FAD+FADH2 coenzyme Q to Complex 3
Carrier C transports to complex 4
4 H+ pumped out

Question 12

Complex 4

Answer 12

Carrier C to 4
combines H+ and O2
2 H+ pumped out
28 molecules of ATP
