anaerboic respiration

Question 1

why does anaerobic respiration occur?

Answer 1

It happens when there is no oxygen present due to vigourous activity so muscle contractions can continue

Question 2

How does lactate become lactic acid?

Answer 2

it’s dehydrationsed

Question 3

Why does lactic acid cause pain?

Answer 3

because it’s an acid so it alters the pH and this affect cellular activity causing pain and cramping

Question 4

How much ATP does anaerobic respiration produce?

Answer 4

only two molecules of ATP, where is aerobic respiration produces around 36

Question 5

How is lactic acid removed?

Answer 5

it is carried by the blood from muscles to the liver, then when oxygen is available it is either converted back into pyruvate for aerobic respiration or recycled into glucose or glycogen

Question 6

What happens to glucose in anaerobic respiration?

Answer 6

-glucose is turned into pyruvate, the same as in aerobic respiration, via glycolysis
-The rNAD produced in glycolysis, then loses H atoms, and these are donated to the pyruvate to make lactate
-The lactic becomes lactic acid due to dehydrogenation
