Question

Describe how food is broken down to make ATP

Answer 1

The breakdown processes must act on food taken in from outside.

Stage 1 in the enzymatic breakdown of food molecules is therefore digestion, which occurs either in our intestine outside cells, or in a specialized organelle within cells, the lysosome.

Stage 2 starts in the cytosol and ends in the major energy-converting organelle, the mitochondrion.

Stage 3 is entirely confined to the mitochondrion.

Hope this helps!

Answer 2

A molecule is a molecule that transfers energy from the breakdown of food molecules to cell processes
