Cellular Respiration
Cellular Respiration 4.4 Overview of Cellular Respiration When there's oxyen, cellular respiration lets out chemical energy from sugar and other carbonbased molecules to make ATP. This respiration occurs in mitochondria. Mitochondrion cannot make ATP from food. Glycolysis breaks down glucose to two three-carbon molecules and makes two molecules of ATP, this process doesn't need oxygen. Two parts of the mitochondrion are involved in cellular respiration. Krebs cycle make molecules that brings energy to the next part of cellular respiration. This cycle takes place in the matrix of the mitochondrion. 38 ATP molecules are created from one glucose molecule. I learned more about the cellular respiration. All I knew back then was that photosynthesis and cellular respiration were opposites. I didn't know about the glycolysis and the krebs cycle. I also never learned where photosynthesis and cellular respiration occur. 4.5 Cellular Respiration Detail (A)
