Question

How does glucose break down in cellular respiration?

Answer 1

Cellular respiration:

1. The process in which organic molecules are biologically oxidized and energy is released in the form of ATP is called cellular respiration.
2. Cellular respiration is basically an amphibolic process that occurs in multi-steps.
3. Most of the steps in the cellular respiration process take place in the mitochondria.
4. A series or chain of chemical reactions is involved in the complex breakdown of glucose.
5. The ultimate aim of cellular respiration is to completely break the carbon-carbon (C-C) bond of the glucose to release energy (ATP).

The steps involved in the breakdown of glucose are as follows:

Glucose → Glycolysis → Pyruvic Acid → Acetyl CoA → Kreb's cycle → Electron transport chain or oxidative phosphorylation →Release of energy

Total ATP yield:

A total of 38 molecules of ATP are yielded from the breakdown of glucose.
