Glycolysis

?
What happens in glycolysis?
The splitting of glucose in a metabolic pathway.
1 of 10
What does glycolysis require?
Glucose/ATP/ADP/Pi/NAD
2 of 10
What is NAD?
A Coenzyme which accepts hydrogen
3 of 10
What does glycolysis produce?
Reduced NAD(NADH) and ATP
4 of 10
Summarise glycolysis in 4 steps?
-Glucose is activated by being phosphorylated
-A bi-phosphorylated hexose sugar is split into 2 phosphorylated triode carbons
-Triose phosphate is oxidised by NAD and a phosphate is added
-ATP is produced by substrate-level phosphate
5 of 10
How many molecules of ATP are used initially in glycolysis?
2 ATP molecules
6 of 10
During aerobic respiration how is additional energy produced?
From reduced NAD(NADH)
7 of 10
How many molecules of NADH are produced per glucose?
2 molecules
8 of 10
What is the additional energy available due to?
It is due to the reduced NAD passing into the mitochondrion to produce more ATP by oxidative phosphorylation
9 of 10
What happens when pyruvate is transported into the mitochondrion ?
If oxygen is present, it is further metabolised
