Photosynthesis and Respiration- Respiration Flashcards
What are the two types of respiration?
Aerobic and anaerobic respiration
What is the main difference between aerobic and anaerobic respiration?
Aerobic requires oxygen and anaerobic does not
What are similarities between aerobic and anaerobic respiration?
Both produce ATP and both start with glycolysis
What does glycolysis involve?
Splitting one molecule of glucose (6C) into two smaller molecules of pyruvate (3C)
Where does glycolysis happen?
In the cytoplasm of cells
Is glycolysis an aerobic or anaerobic process?
Anaerobic as it doesn’t need oxygen to take place
What are the two stages in glycolysis?
Phosphorylation and oxidation
What is the result of glucose being phosphorylated using a phosphate from a molecule of ATP?
Creates 1 molecule of glucose phosphate and 1 molecule of ADP
How is hexose biphosphate formed?
ATP is used to add another phosphate
What is formed when hexose biphosphate is split?
2 molecules of triose phosphate
What is formed when triose phosphate is oxidised?
2 molecules of pyruvate are formed
What happens when NAD collects the hydrogen ions?
Forms 2 reduced NAD
Why is there a net gain of 2 ATP?
Because 4 ATP are produced, but 2 were used up in stage one
What is pyruvate converted to in plants and yeast in anaerobic respiration?
Ethanol
What is pyruvate converted to in animals in anaerobic respiration?
Lactate
