Can cells that carry on aerobic respiration operate anaerobically if needed?
Cells can usually make up for a lack of oxygen to produce energy with anaerobic respiration. For example, when doing heavy physical exercise like lifting weights (i.e. anaerobic exercise), the amount of energy required of the muscle cells exceeds the amount the cells are able to make through aerobic respiration given the amount of oxygen they get. So they compensate by using anaerobic respiration (glycolysis and fermentation of pyruvic acid) to produce that extra ATP. However, the byproduct of this anaerobic respiration, lactic acid, accumulates in the cells and body and is toxic. It has to be processed and broken down by the liver (when it accumulates in the muscles, for example, it causes muscle aches after exercise). So most animal cells cannot survive indefinitely solely on anaerobic respiration, but can supplement their energy generation with it if necessary.
What are the differences between respiration and fermentation?
Respiration: the physical and chemical processes by which an organism supplies its cells and tissues with the oxygen needed for metabolism and relieves them of the carbon dioxide formed in energy-producing reactions. Fermentation: an enzymatically controlled anaerobic breakdown of an energy-rich compound (as a carbohydrate to carbon dioxide and alcohol or to an organic acid). Both definitions were obtained from the Merriam-Webster website.
Why is it better for human muscle cells to produce energy through aerobic respiration?
First of all, an efficient respiration system is vital for ALL sportspeople, not just some. But it is vital because your muscles need oxygen to continually perform at a high level. When you engage in physical activity such as a sport, your muscles fatigue and lose oxygen which needs to be replaced in order for you to be able to keep playing. An efficient respiration system transports oxygen quicker to the muscles then an average respiration system does. But sportspeople do certain drills and running to improve the respiration system, typically called cardio.
Do Anaerobic bacteria require oxygen?
Anaerobic organisms obtain energy without using oxygen as the final electron acceptor. They use sulfate, nitrate or sulfur as the final electron acceptor. This doesn't form as much energy as oxygen will. These microbes do fill a niche that aerobes can't fill.
Two examples of physical activities in the anaerobic system?
marathon runner, long distant swimmers basically anything that is an endurance event
In which situation does anaerobic respiration take place in?
When the body doesn't have the physical strength to maintain the oxygen levels needed for aerobic respiration. As a result of this, lactic acid will be produced.

What are the two aspects of every physical exercise?
aerobic and anaerobic
What is physical respiration?
Physical respiration involves the physical changes that are needed in order to breathe. An example of this would be the muscles contracting and expanding to inhale or exhale.
Is cellular respiration a physical property?
Cellular respiration is a biochemical process.
What is the average non-athlete respiratory rate?
Athletes have higher respiration rate than non athletes because the athletes are always used to excercising their lungs by breathing synchronically whenever they do strenous physical activities while non-athletic people are not used to excercising their lungs thus its lung volume capacity is lower when compared to athletes. Physical excercise is also a best way to increase blood circulation in the body hence allowing efficient diffusion of oxygen to our tissues.
What do aerobic and anaerobic exercises have in common?
They both promote physical endurance.
Processes involved in anaerobic respiration?
Anaerobic Glycolysis occurs in our muscle cells during high intensity physical activity and the system last up to 3 minutes. Glycolysis is the break down of sugar
Is respiration physical or chemical change?
Chemical.
What do aerobic exercise and anaerobic exercises have in common?
They both promote physical endurance.
What has the author Richard A Winett written?
Richard A. Winett has written: 'Ageless athletes' -- subject(s): Athletes, Biography, Physical education and training, Physical fitness, Psychological aspects, Psychological aspects of Physical education and training
Where does aerobic and anerobic respiration take place?
Aerobic refers to action where oxygen is able to be introduced. Anaerobic refers to a lack of oxygen. Aerobic exercise is a physical activity that allows the participant to breathe and replenish their supply of oxygen such as long distance running. Anaerobic exercise uses oxygen faster than the body is able to replenish it. The cells use any stored oxygen but have to operate without their supply being replenished for a short time. Sprinting would be an anaerobic activity.
