Question

How does glycolysis contribute to the overall process of cellular respiration?

Answer 1

Glycolysis is the process of taking sugar and converting it into 2 pyruvic acids. It is also the first process in cellular respiration.

Explanation:

So first there is glycolysis that occurs in the cytoplasm outside the mitochondria, then the sugar that goes in gets turned into 2 pyruvic acids. The pyruvic acids go into the Krebs cycle and get transformed into energy for the ETC of where the most ATP is produced.

Remember, the Krebs cycle is where the electrons are taken from the chemicals going through. This is also the second process of cellular respiration.

The ETC has the concentration gradient working in its favor by getting hydrogen to one side, then traveling over to the ATP synthase area of where the electrons power it, H+ collides with ADP to create ATP and that is why the mitochondria are called the powerhouse of the cell. This is the last process of cellular respiration.

I hope that this helps and I wish you good days.
