One day in 1950s UK, a woman named Stacey asked a man named Adolf Krebs why people eat.
Ever wonder why we eat? Do we just do it because we're hungry, or is it part of that cell stuff you study?
It sure does involve the processes that a cell goes through, lets go on a walk and talk about it.
SALAD ON A PLATE!
Excited by the question, Krebs went on a rant explaining cellular respiration
What do you mean by all the letters? I never took chemistry, so I don't know what those element compounds represent.
On the most basic level, as the dog consumes food, a source of C6H12O6 and takes in O2, the dog produced CO2, H2O and ATP. Do you understand so far?
DOGS WITH FOOD!
Understanding that he may be going too fast, Krebs decided to slow down and give the word explanation for cell respiration
Alright, I'll try to make it as simple possible. All living things breath in oxygen, a part of air. All living things use food too, which tends to be glucose. The oxygen and glucose are then react within a body to produce energy in the form of a compound with energy stored in phosphate bonds, carbon dioxide and water.
KREBS LAB RECEPTION
Understanding the equation, but still skeptical, Stacey asked for more information regarding parts of the process
KREBS LAB ROOM
Soo... is it just that simple? Does the entire body just turn food into energy, or just part of the body? Are there any steps in between?
Eager to show his work, Kreb whipped out a microscope and a cell and prepared them on the table for his guest
CELLULAR RESPIRATION, PART 1 of 1
KREBS LAB ROOM
For your second question, the answer is the mitochondria, the alleged "powerhouse" of the cell. It looks like the circle with squiggly lines through it.
Sadly, Stacey had to leave because she had kids to take care of and was starting a career as a biology teacher
Thanks for having me, but I'm afraid I can't stay. I will say, however, that your provided great information with the vocab words used, the chemical equations (though I didn't understand the elements) and the word equation! Hope to see you soon!
OH! I forgot to mention one thing, cellular respiration, not including fermentation, is aerobic, meaning it uses oxygen as a reactant. Fermentation is anaerobic, and does not need oxygen to occur
Krebs Lab Reception
I'm glad you asked. To answer your first question and last question, it is not that simple, there are many parts such as glycolysis, Krebs cycle (named after myself) and fermentation, a process that does not need oxygen
