Explanation

Question 2 of 26

1

During Respiration, what happens?

Select one or more of the following:

Explanation

Question 6 of 26

1

The term respiration has two meanings.

Explanation

Question 7 of 26

1

What are the two stages of Respiration?

Select one or more of the following:

  • 1- In the Cytoplasm ; The molecules of glucose are broken down into smaller molecules

  • 1- In the Fermentation ; the Cytoplasm breaks down the muscles
    2- The Respiration in the Mitochondria

Explanation

Question 8 of 26

1

Why is the Mitochondria often called the Powerhouses of the Cell?

Select one of the following:

  • It makes the small molecules beak down into even smaller molecules

  • When chemical reactions require oxygen and release a great deal of energy

  • The molecules of glucose are broken down into smaller molecules

Explanation
