In the presence of oxygen glycolysis is followed by?
Krebs cycle.
If humans and other animals are capable of glycolysis why do you need to breathe oxygen?
the krebs cycle and electron transport chains that provide the majority of the ATP gain require oxidative phosphorilation, the oxygen plays the part of a electron acceptor at the end of the etc
What can stop the Krebs cycle?
Lack of oxygen.
When can the Krebs cycle not occur?
when oxygen is not present
Krebs cycle anaerobic or aerobic?
Aerobic. The Krebs cycle is a way of producing ATP using oxygen. The use of oxygen for energy production means Aerobic (as opposed to Anaerobic or without-oxygen).
Where does the Krebs cycle occur in humans?
mitochondrial matrix
What most the Krebs cycle have that glycolysis doesnt require?
pyruvate
What are the three stages of cellular respiration in order?
Glycolysis, the Citric Acid Cycle (Krebs Cycle), and the Electron Transport Chain.
What happens to carbon dioxide produced during the Krebs cycle?
The CO2 produced by the Krebs cycle is a waste product; it is disposed of as waste. In humans, we breath in oxygen with our lungs, use that oxygen in cellular respiration, and breath out the waste CO2. It should be noted that air is not made entirely of Oxygen and carbon dioxide, and that our bodies are not efficient enough to consume all of the available oxygen in each breath, and that therefore, what humans exhale is not 100% CO2.
What is a term for the process of converting oxygen and nutrients into ATP?
"Krebs cycle"
When oxygen is available a cell will begin what happens after glycolysis?
krebs cycle
If oxygen is not utilized in the Krebs Cycle why is it called aerobic respiration?
The answer is the Krebs Cycle is only one step in aerobic respiration. The Krebs cycle strips away carbon from the molecule being catabolized in order to free up electrons. These electrons then go on to the electron transport chain, which requires oxygen.
