Question

PLEASE HELP! PLEASE GIVE THE ANSWERS TO THE QUESTIONS THAT FOLLOW -:
1. The exchange of gases at the cellular level is called ___________.
2. Differentiate between -:
i) Catabolic and Anabolic process
ii) Inhaled and Exhaled air

Answer 1

2.(1.)Anabolism refers to the process which builds molecules the body needs; it usually requires energy for completion. Catabolism refers to the process that breaks down complex molecules into smaller molecules; it usually releases energy for the organism to use.

1.external respiration

2.(2) The difference between the amount of oxygen in inhaled and exhaled air is equal to the difference in the amount of carbon dioxide in exhaled and inhaled air. The special adaptions of the alveoli for gas exchange are: Thin walls. Huge surface area.

Answer 2

here is your answer

1.EXTERNAL RESPIRATION

2.Catabolic processes break down complex compounds and molecules to release energy. This creates the metabolic cycle, where anabolism then creates other molecules that catabolism breaks down, many of which remain in the organism to be used again

3.The difference between the amount of oxygen in inhaled and exhaled air is equal to the difference in the amount of carbon dioxide in exhaled and inhaled air
