Introduction
The goal of aerobic cellular respiration is to produce energy, in the form of ATP, by breaking the foods that one eats with the use of oxygen. ATP Adenosine Tri-
phosphate
Aerobic cellular respiration has three major steps Glycolysis The Kreb’s Cycle Oxidative
Phosphorylation(Electron Transport Chain)

Introduction II
During the processes of cellular respiration, ATP is produced via two methods Substrate Level
Phosphorylation Oxidative
Phosphorylation

Substrate Level Phosphorylation
Substrate level phosphorylation The removal of
phosphate, from a substrate, and adding it to ADP. ADP + P ATP
Requires the use of an enzyme.
Occurs during glycolysis and the Kreb’s Cycle

Oxidative Phosphorylation
Oxidative phosphorylation Occurs at the electron
transport chain. Requires the use of
oxygen. Molecules known as
NADH (nicotinamide adenine dinulceotide), or FADH (flavin adenine dinucleotide) are oxidized. NADH and FADH donate
electrons to the ETC and are eventually used to produce H2O from the oxygen that breathed in by the organism.

Oxidative Phosphorylation II
Oxidative phosphorylation After those events have
occured, ATP is produced via an underlying process known as chemiosmosis. Chemiosmosis occurs
during oxidative phosphorylation.

The Processes of Aerobic Cellular Respiration
![Page 8: Aerobic Cellular Respiration Packet #13 Chapter #4](https://reader035.vdocument.in/reader035/viewer/2022081519/56649f4a5503460f94c6c198/html5/thumbnails/8.jpg)
Glycolysis
Glycolysis is a ten step process, occurring in the cytosol of the cell, that splits glucose in two molecules (pyruvate) while producing limited amounts of ATP (substrate level phosphorylation) and NADH. Glyco – sugar Lysis – split apart

The Kreb’s Cycle
The Kreb’s Cycle, occurring in the mitochondria matrix, is an eight step process that produces limited amounts of ATP (via substrate level phosphorylation), FADH and NADH.

Oxidative Phosphorylation
The electron transport chain is found along the inner membrane of the mitochondria and IS the location for oxidative phosphorylation.
Electrons are removed from the previously produced NADH and FADH.
The electrons, move along the chain causing hydrogen ions to move.
The hydrogen ions, that moved, drives ATP synthase to produce ATP (chemiosmosis). 1 NADH 3 ATP’s 1 FADH 2 ATP’s

Final Overview
As a result of aerobic cellular respiration a total of 36 – 38 ATP’s per glucose molecule. 4 ATP’s via substrate
level phosphorylation
