Which 2 gases are exchanged at the surface of the air sac?
Oxygen and carbon dioxide are exchanged at the surface of the air sac. Oxygen is taken in from the air into the bloodstream, while carbon dioxide is released from the bloodstream into the air to be exhaled.
What does burning use to produce carbon dioxide - OXYGEN or CARBON?
Burning uses oxygen to produce carbon dioxide. During combustion, when a material reacts with oxygen, it releases carbon dioxide as a byproduct.
What is the name of the process that uses oxygen to make carbon dioxide?
The process that uses oxygen to make carbon dioxide is called cellular respiration. In this process, cells break down glucose molecules to produce energy, carbon dioxide, and water.
What is a sentence that uses the word carbon oxygen cycle?
The carbon oxygen cycle describes the interplay between carbon dioxide and oxygen in Earth's atmosphere, with plants absorbing carbon dioxide during photosynthesis and releasing oxygen, while animals and other organisms consume oxygen and produce carbon dioxide through respiration.
Why does oxygen decrease after exercise and carbon dioxide increase?
During exercise, your body uses more oxygen to produce ATP for energy. This leads to a decrease in oxygen levels in the blood. As a byproduct of this increased oxygen consumption, carbon dioxide is produced and accumulates in the blood, leading to an increase in carbon dioxide levels.
