Respiration Flashcards
1
Q
Name the two types of respiration.
A
- Aerobic and anaerobic respiration.
2
Q
What is the difference in ATP produced in aerobic and anaerobic respiration?
A
- Both produce ATP.
- Aerobic respiration produces more ATP than anaerobic.
3
Q
Which process starts both aerobic and anaerobic respiration?
A
- Glycolysis
4
Q
What does glycolysis produce from glucose?
A
- Pyruvate
5
Q
Where does glycolysis happen?
A
- Cytoplasm
6
Q
What is the phosphorylation process of glycolysis?
A
- Glucose is phosphorylated using a phosphate molecule from ATP. This creates 1 molecule of glucose phosphate and 1 molecule of ADP.
- ATP is then used to add another phosphate, forming hexose biphosphate.
- Hexose biphosphate is then split into 2 molecules of TP.
7
Q
What is the oxidation process of glycolysis?
A
- TP is oxidised (loses H), forming 2 molecules of pyruvate.
- NAD collects H ions, forming 2 reduced NAD.
- 4 ATP are produced. There’s a net gain of 2 ATP.
8
Q
Anaerobic respiration - alcoholic fermentation.
A
- Pyruvate is decarboxylated (CO2 removed).
- Pyruvate becomes ethanal.
- Reduced NAD loses H ions, becoming NAD.
- Ethanal becomes ethanol.
9
Q
Anaerobic respiration - lactate fermentation.
A
- Reduced NAD loses H ions, becoming NAD.
- Pyruvate becomes lactate (lactic acid).
