When you run fast there is a chemical reaction called anaerobic respiration. This reaction transfers energy from glucose to your cells without oxygen. There is just
one waste product
called lactic acid. … A molecule of lactic acid contains atoms of carbon, hydrogen and oxygen.
Where is lactic acid produced during anaerobic respiration?
Lactic acid produced in
muscle cells
is transported through the bloodstream to the liver, where it’s converted back to pyruvate and processed normally in the remaining reactions of cellular respiration.
How is lactic acid produced?
Lactic acid is mainly produced in muscle cells and red blood cells. It forms
when the body breaks down carbohydrates to use for energy when oxygen levels are low
. Times when your body’s oxygen level might drop include: During intense exercise.
What happens to lactate in anaerobic respiration?
The lactate produced as a result of anaerobic respiration must be removed as it is acidic. There are two main way to do this; The
lactate is transported to metabolically active cells
, such as the heart and brain. Here it is converted back to pyruvate by the above reaction.
How is the lactate produced from anaerobic respiration helpful?
Anaerobic glycolysis is the transformation of glucose to lactate when limited amounts of oxygen (O
2
) are available. Anaerobic glycolysis is only an effective means
of energy production during short, intense exercise
, providing energy for a period ranging from 10 seconds to 2 minutes.
Where lactic acid is found?
Lactic acid is mainly produced in
muscle cells and red blood cells
. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low.
What exercise produces lactic acid?
Most people associate lactic acid with intense exercises, like
sprinting or heavy lifting
, and rightly so. Lactic acid is a by-product of glycolysis, one of the metabolic processes the body uses to produce energy during intense exercise.
How is lactic acid removed after anaerobic respiration?
When a period of exercise is over, lactic acid must be removed from the body. The body’s tolerance of lactic acid is limited. Lactic acid is taken to the liver by
the blood
, and either: oxidised to carbon dioxide and water, or.
What are the 3 stages of anaerobic respiration?
This process occurs in three stages:
glycolysis , the Krebs cycle , and electron transport
. The latter two stages require oxygen, making cellular respiration an aerobic process.
What are the disadvantages of anaerobic respiration?
Disadvantages: Anaerobic respiration
generates only two ATPs and produces lactic acid
. Most lactic acid diffuses out of the cell and into the bloodstream and is subsequently absorbed by the liver. Some of the lactic acid remains in the muscle fibers, where it contributes to muscle fatigue.
What is the main purpose of anaerobic respiration?
Anaerobic respiration is the
process of creating energy without the presence of oxygen
. Sometimes the body can’t supply the muscles with the oxygen it needs to create energy – such as in a sprinting situation.
Do humans produce lactic acid?
There are many myths about lactic acid. Perhaps the greatest of all is the notion that there is lactic acid in the human body. There is not.
The body actually produces lactate
, which is lactic acid minus one proton.
Where does anaerobic respiration occur?

What fruit has lactic acid?
| Lactic acid bacteria species Source | Lactobacillus plantarum Tomatoes, marrows, carrots, cucumbers, eggplants, red-beets, capers, pineapple, plums, kiwi, papaya , fennels, cherries, cabbages | Lactobacillus pentosus Capers, papaya, eggplants, cucumbers |

Which milk has the most lactic acid?
Buttermilk
contains between 3-4% lactic acid which is much higher than levels found in yogurt.
What foods cause lactic acid?
- Bread and beer.
- Soy products such as tofu and soy milk.
- Cheese.
- Pickled vegetables such as kimchi and sauerkraut.
- Pickled meats such as salami.
- Legumes such as beans and peas.
