Question

Explain this please: Glucose + O2 --(enzyme)--> ATP + CO2 +H2O.

Answer 1

There is no 1 enzyme that achieves this. it's a multistep breakdown called glycolysis.

Answer 2

THANK YOU but would you mind explaining what glycolysis is. my bio teacher barely teaches and i have to take a regents on bio in 20 days

Answer 3

Glycolysis is the metabolisation of Glucose. the picture illustrates the multiple steps that takes place and what happends to the glucose molecule in every step.
To try to explain this as simple as possible for you... Glucose can't be used as energy, it needs to be converted into a universal bodily energy molecule called Adinosine triphosphate (ATP). When a cell doesn't have access to oxygen, Glycolysis is the most optimal energy metabolism it can achieve which is 1molGlucose -> 2 ATP + 2 CO2+ H2O.
This occures in the Cytoplasma of a cell. If the cell has access to Oxygen and isn't a erytrocyte (Red blood cell) Aerobic (with oxygen) respiration occures which yield a much greater profit in ATP, somewhere between 28-32 (different books will say different numbers due to that it's only a approximation.).

Did my rambling clarify this or do you have any further questions?

Summary: Glycolysis is the cellular respiration during Anaerobic (without oxygen) enviroment inorder to utilize the energy that is freed from breaking down the Glucose molecule.

Answer 4

OMG THANK YOU!!!!!!!!!! That was very helpful! you realize that now im not gonna stop bothering you about biology lol!

Answer 5

I have no problem with that. Fire away.

Answer 6

I'll be back tomorrow :D
