Glycolysis

Question 1

Where does glycolysis occur?

Answer 1

cytoplasm

Question 2

What is glycolysis involved in?

Answer 2

aerobic AND anaerobic respiration

Question 3

What is the 1st stage of glycolysis?

Answer 3

glucose is phosphorylated forming glucose phosphate, using ATP

Question 4

What is the 2nd stage of glycolysis?

Answer 4

the production of triose phosphate

Question 5

What is the 3rd stage of glycolysis?

Answer 5

oxidation of triose phosphate to form pyruvate

Question 6

What are the end products of glycolysis?

Answer 6

net gain of 2 x ATP
2 x reduced NAD (NADH)
2 x pyruvate

Question 7

How many ATP are hydrolysed for the phosphorylation of glucose?

Answer 7

2

Question 8

Why does glucose phosphate split?

Answer 8

it is unstable

Question 9

For 1 GLUCOSE molecule, how many ATP are produced (in the oxidation of triose phosphate(s))

Answer 9

4 (2 per TRIOSE PHOSPHATE)

Question 10

What is NAD converted into in the oxidation of triose phosphate to form pyruvate?

Answer 10

NADH (2 per GLUCOSE)

Question 11

How many pyruvate are made for each glucose molecule?

Answer 11

2

Question 12

What is produced in glycolysis and is needed in the next stages of respiration?

Answer 12

NADH and pyruvate

Question 13

How are pyruvate and NADH transported into the mitochondrial matrix?

Answer 13

active transport
