Glycolysis, Krebs cycle and the electron transport chain.
Glucose, polysaccharides and discaccharides go into glycolysis and that cycle can produce 2 ATP (adenosine triphosphate).
Electrons are transfered to the Electron Transport chain. Pyruvic acid fermentation can make 2 ATP then goes down, releasing 2 NADH2 to the Electron Transport chain, with Acetyl CoA into the Krebs cycle which makes 4 CO2 and 4 ATP as well as sends 6 NADH2 and 2 FADH2 down to the electron transport chain.
The 2 NADH2, 2 NADH2, 6 NADH2 and 2 FADH2 then go down the electron transport chain realeasing energy a bit each time it goes down and in the end 34 ATP is created.

What element must be present for both steps of cellular respiration to occur?
oxygen
Do all of the steps of cellular respiration need oxygen?
No; and those that do not are called anoxic steps.
Which steps in aerobic cellular respiration require oxygen?
electron transport chain
Why is oxygen so important in cellular respiration?
Oxygen is needed for the Electron Transport Chain, or ETC for short. Oxygen's role in ETC is as the final acceptor of electrons. The transfer of electrons pumps hydrogen protons across the inner mitochondrial membrane through ATP Synthase and this gradient is used to synthesize energy in the form of ATP. This step produces around 30 ATP, this being the most out of all of the three steps of cellular respiration.
Which steps of cellular respiration occur in the cytoplasm?
glycolysis
What element must be present for both steps of cellular respiration to occur?
oxygen
Steps of cellular respiration if oxygen is NOT present in the cell?
If oxygen is not present in the cell, it automatically goes into a process called fermentation. This produces chemical energy with no oxygen needed.
Do all of the steps of cellular respiration need oxygen?
No; and those that do not are called anoxic steps.
Which steps in aerobic cellular respiration require oxygen?
electron transport chain
How are the step of cellular different when it is anaerobic respiration?
The steps of cellular respiration is different when it is anaerobic respiration compared to aerobic respiration. The main difference is because aerobic respiration uses oxygen and anaerobic uses other elements but the other steps are similar.

What are the 2 steps in respiraton?
The 2 steps of respiration are;breathing and cellular respiration.
How are steps of cellular respiration different when it is anaerobic respiration?
Anaerobic means without air, so there is no respiration.
What is the main fuel for cellular respiration?
the main fuel for cellular respiration is protein, fat, sugar, and oxygen from the food you eat.
What does it mean to say that glycolysis is an aerobic process?
Cellular respiration sometimes is referred to as aerobic respiration, meaning that it occurs in the presence of oxygen, and is not an anaerobic process. Glycolysis is one of the processes in cellular respiration. In the final steps of glycolysis, two hydrogen atoms are removed from each three-carbon compound by bonding to free-floating oxygen atoms in the cytoplasm to form water.
When is oxygen used in cellular respiration?
I. Cellular Respiration: breaking down sugar in the presence of oxygen (aerobic).Photosynthesis (you recall...) is the process by which CO2 and H2O are used to make sugars and starches.During Cellular Respiration, sugar is broken down to CO2 and H2O, and in the process, ATP is made that can then be used for cellular work.The overall reaction for cellular respiration: (does this reaction look familiar? Overall, it is the reverse reaction of photosynthesis, but chemically, the steps involved are very different.)C6H12O6 + 6O2 -------------------> 6CO2 + 6H2O + ~38 ATP
