Metabolic pathways and ATP production I

Question 1

What are the net products of glycolysis?

Answer 1

2 ATP + 1 NADH

Question 2

Which steps of glycolysis use and produce ATP?

Answer 2

Glucose –> G6P (-ATP)

Fructose-6-phosphate –> Fructose-1,6-bisphosphate (-ATP)

1,3-bisphosphoglycerate –> 3-phosphoglycerate (+ATP)

Phosphoenolpyruvate –>Pyruvate (+ATP)

Question 3

What are the three fates of pyruvate?

Answer 3

Alcoholic fermentation Generation of lactate Generation of Acetyl-CoA

Question 4

What does the pyruvate dehydrogenase complex consist of?

Answer 4

Lipoamide Reductase Transacetylase (Lipoamide)
Dihydrolipoyl Dehydrogenase (FAD)
Pyruvate Decarboxylase (Thiamine Pyrophosphate)
Other co-factors: NAD+ and CoA
