1) Oxidative phosphorylation relies on the energy taken from oxidation-reduction reaction in the electron transport chain to produce ATP. Substrate-level phosphorylation is the formation of ATP by binding an organic phosphate to ADP, or the transferring of phosphates. This type of reaction occurs during the Krebs cycle and glycolysis with the help of kinase enzymes. On the other hand, the electron transport chain converts the chemical energy, electrons, in the C – H bonds by way of Oxygen’s electronegativity to drive the oxidative phosphorylation which accounts for the majority of ATP in cellular respiration. 2) Glucose + 2ADP + Pi + 2NAD+ 2Pyruvate + 2NADH + 2ATP NADH is a coenzyme so it is constantly undergoes redox reactions and is reused. ATP is used to power reactions in the cell by breaking its high energy phosphoanhydride bonds. The pyruvates, in the presence of oxygen, are oxidized and form Acetyl CoA which later go on to the Krebs Cycle. 3) A cell is never able to stop catabolism after glycolysis because the primary enzyme
