Cellular Respiration?

Question

I have a few questions on cellular respiration. Is it a chemical chande or physical change? does it take place in every organism such as fungi and bacteria too. Does cellular respiration gove pf materials needed for digetion? Can you explaim to me what it really is in a non-complicated form. I don't really get it becasue all the other webs have it all complicated. I dont need the formula either! THANKS A BUNCH!

Answer 1

Here's a quick summary of cellular respiration.

Cellular respiration is the process used by cells to break down glucose molecules and get the energy out of the molecules for the cells to use. Glucose molecules have energy stored in their bonds. Breaking the bonds lets the energy loose. Cellular respiration puts this energy in the form of ATP molecules that the cells can use readily.

All kinds of organisms carry on cellular respiration because all kinds of organisms need energy for their cells to use.

Many students get cellular respiration mixed up with the kind of respiration that is involved with breathing. Actually, they are related because lungs take in oxygen and give off carbon dioxide for the whole body. Cellular respiration uses oxygen and produces carbon dioxide in the cells.

Now, to answer your questions.
1. It's a chemical change because molecules are broken and rearranged.
2. It happens in every kind of organism because they all need to get energy out of molecules.
3. Cellular respiration doesn't make materials needed for digestion, but it does make molecules that are used for energy.

Good luck!

Answer 2

Chemical Process Of Cellular Respiration

Answer 3

Cellular respiration means breaking down glucose to release energy in the form of ATP. There are two different types: aerobic and anaerobic. A lot more ATPs are generated in aerobic respiration, where oxygen is the electron acceptor. All cells including bacteria or fungi must get their energy by respiration. So cellular respiration is not about exchange of oxygen and carbon dioxide. It is chemical reactions to release energy.

Answer 4

since it's cellular,it must be chemical.b'cos inhalation and exhalation are examplas of physical mechanism.it takes place in all organisms alyhough each species/type do it differently b'cos how do u stay alive without it?cellular respiration provides energy so i'm sure it helps in digestion.
