Anaerobic repsiration

Question 1

Example of animal tissue that may undergo anaerobic respiration

Answer 1

Muscle tissue

Question 2

In absence of o2 only glycolysis happens

Why

Answer 2

Cos no o2 to act as final electron acceptor in etc

Question 3

Net atp in anaerobic

Answer 3

2 cos only glycolysis happens

Question 4

How do you get energy atp in anaerobic

Answer 4

From glycolysis again and again 2 net atp

Question 5

Describe anaerobic how it happens in animal cells

Answer 5

In animal cells pyruvate becomes reduced accepting the hydrogen from reduced NAD to form lactateand oxidised NAD.

This reaction is Catalysed by lactate dehydrogenase

Question 6

Describe anaerobic how it happens in yeast and higher plant cells

First explain the extra step that makes pyruvate to ethanal

Answer 6

All steps same first

Then after pyruvate is made- co2removed - enzyme ethanal dehydrogenase

Ethanal becomes reduced Accepting H from redNAD to form ethanol.
