Question

During respiration, glucose and oxygen enter our body cells and waste products carbon dioxide and water leave the body cells by the process of (a) effusion
(b) osmosis
(c) diffusion
(d) plasmolysis

Answer 1

(c) diffusion

Explanation:

• Respiration is a process which happens in our bodies throughout our lives.

• Now we see that in the process of respiration glucose and oxygen combine to give out carbon dioxide and water.
• These are considered waste products which leave our body.
• We notice that these waste products are moving from higher concentration to lower concentration.
• The process by which substances move from higher concentration to lower concentration is called diffusion.
• Hence we conclude that diffusion is the process involved in excretion of the waste products.

Answer 2

Answer is Option (C)

Explanation:

1. The average passive movement of an elements (atoms, molecules, or ions) from a place or membrane of more concentration to lower concentration is called Diffusion.
2. And the process keeps going throughout but uniformly.
3. During respiration, glucose and oxygen enter our body cells and waste products carbon dioxide and water leave the body cells by the process of diffusion.
