Cell Respiration is a process your cells do to make energy. You need to breathe in order for your cells to do the process of cell respiration and make energy.
When you inhale, what gas are you taking from the air?
Have you ever wondered where that oxygen goes?
From your lungs, it diffuses into your blood.
Its ultimate destination: your cells
When the oxygen-rich blood reaches your cells, oxygen diffuses across the cell membrane and into the cells.
Your cells will use the oxygen to do cell respiration and make ATP energy.
Carbon Dioxide is a waste product of cellular respiration.
So, it diffuses out of your cells and into your bloodstream.
Once it arrives at your lungs, it diffuses out of the blood and into your lungs.
Then, you exhale it.
So, the reason you breathe is in order for your cells to do cell respiration.
Are you the only thing that does cell respiration?
All living things do cell respiration.
Animals do cell respiration!
Plants do cell respiration!
Even bacteria do cell respiration!
So, what is cell respiration?
The chemical equation for aerobic cell respiration may look familiar to you.
6 O2 + C6H12O6 6 CO2 + 6 H2OOxygen+Glucose Carbon Dioxide + Water
The aerobic cell respiration equation is the opposite of photosynthesis!
What are some organisms that do aerobic cell respiration?
Animals (including humans)
Aerobic cell respiration requires oxygen
In the process of breaking down glucose, aerobic cell respiration makes a net of 36 ATP molecules.
Remember,Cells use ATP for energy
Where in the cell does aerobic cell respiration occur? IN THE MITOCHONDRIA!
Is there another type of cell respiration?YES!
Some organisms such as yeast and bacteria do anaerobic cell respiration.
What does anaerobic mean?Without oxygen
Products of anaerobic respiration include:The carbon dioxide produced is used to make bread riseThe ethyl alcohol produced is used in wine and beer.
And, if youve ever worked out too hard and your muscles ache.. Lactic Acid Fermentation is when your muscle cells produce lactic acid through anaerobic cell respiration
Anaerobic cell respiration is less efficientIt only produces a net of 2 ATP molecules
Lets ReviewThere are two types of cell respiration
Aerobic requires oxygenThe products of aerobic are carbon dioxide and waterAerobic yields 36 ATPAerobic happens in the mitochondria of eukaryote cells
Anaerobic does not require oxygenThe products of anaerobic are carbon dioxide and alcohol or lactic acidAnaerobic yields 2 ATP
