Question 1

The order of stages in cellular respiration

Answer 1

1. glysolysis
2. Link reaction
3. Krebs cycle
4. Electron Transport Chain (ETC)

Question 2

The inputs and outputs of Cellular Respiration

Answer 2

inputs
-glucose + oxygen + ADP
Outputs
-Water + Carbon dioxide + ATP

Question 3

glycolysis

Answer 3

located in cytoplasm
inputs
-glucose+ 2 NAD+ + 2 ADP
outputs
- 2 pyruvate+ 2 NADH+ 2 ATP

Question 4

link cycle

Answer 4

located in mitochondria
inputs
-2 pyruvate+ 2 NADH
outputs
-Actyel-CoA+ NADH+ 2 CO2

Question 5

Krebs cycle

Answer 5

Located in mitochondria
inputs
-acetyl-CoA+ 3 NAD+ +3 FAD+ 2 H2O + ADP
outputs
-3 NADH+ 3 FADH2+ 2 CO2+ 2 CoA+ ATP

Question 6

ETC
(electron transport chain)

Answer 6

in mitochondria
inputs
-NADH+FADH2+O2
outputs
-ATP+NAD+ +FAD +H2O

Question 7

what happens when no oxygen

Answer 7

ETC and Krebs cycle, would get backed up and stop
glycolysis keeps going because of fermentation.

Question 8

alcohol fermentation vs lactic acid fermentation

Answer 8

AF
-pyruvate to ethanol+ CO2
- wine beer and bread
- bead end process (cant reverse reaction )
LAF
Private to lactic acid
-cheese, anaerobic exercise
-reversabel
-once O2 is converted back to pyruvate by the liver

Question 9

Both

Answer 9

_ occurs during lack of oxygen (anaerobic respiration)
- use pyruvate from glycolysis
-regenerate NAD+ so glycolysis continues
