Anerobic Respiration & Uses

Question 1

Where does Anaerobic respiration release energy?

Answer 1

Inside the cytoplasm of living cells by breaking down glucose molecules without the use of oxygen

Question 2

What is the word equation for anaerobic equation in plant cells (and some microbial cells)?

Answer 2

Glucose —> Carbon Dioxide + Ethanol + Energy Released

Question 3

What is the word equation for anaerobic equation in animal cells and in some bacteria?

Answer 3

Glucose —> Lactic Acid + Energy Released

Question 4

When does anaerobic respiration occur?

Answer 4

In conditions of very low or where no oxygen is present.

Question 5

Give an example of this

Answer 5

In bacterial cells inside a puncture wound

Question 6

Which is more efficient? Aerobic respiration or anaerobic respiration?

Answer 6

Aerobic respiration is much more efficient and releases much more energy per glucose molecule

Question 7

How is anaerobic respiration useful?

Answer 7

It provides a little more energy to cells when very necessary

Question 8

Give another reason how it is useful

Answer 8

Anaerobic respiration in yeast is used in baking. Yeast in bread dough releases Carbon Dioxide, which makes the dough rise before baking

Question 9

Give another reason how it is useful

Answer 9

In sewage, anaerobic microbes can be added to the solid matter. These microbes break down sewage and releases methane gas, which is collected. This gas is now called biogas and is used for electricity
