Aerobic and Anaerobic Respiration

How Aerobic and Anaerobic Respiration Works?

Aerobic and Anaerobic Respiration

Every Human Being needs Energy to Survive. For humans food is the source of energy and oxygen is required by food to release this energy. Respiration is the process by which body obtains and utilizes oxygen and eliminates carbon dioxide. There are three processes of respiration in humans, these are, breathing, internal respiration and cellular respiration.

Breathing is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide. Internal respiration is the exchange of substances between capillaries and cells, whereas, cellular respiration is the release of energy from food substances in living cells. Today we will discuss cellular respiration only.

Cellular Respiration

The release of energy from food substances in all living cells is called cellular respiration. There are two kinds of cellular respiration aerobic and anaerobic.

Aerobic respiration is the process by which oxygen-breathing creatures turn fuel, such as fats or sugars, into energy. The key organelle of aerobic respiration is the mitochondria where the glucose molecule goes through a multistep process, mainly Glycolysis, Kreb’s cycle and electron transport chain. At the end of this multistep process, 36 molecules of Adenosine triphosphate or ATP are generated from only one molecule of glucose. This makes aerobic respiration a very efficient process. All organisms can carry this type of respiration and some yeast.

A simplified equation of aerobic respiration is:
C6H12O6 + 6O2 6CO2 + 6H2O + energy

Where C6H12O6 is glucose, O2 is oxygen, CO2 carbon dioxide and H2O water.

Muscle contraction, protein synthesis, cell division, active transport, growth, transmission of nerve impulse and regulation of body temperature are some of the uses of aerobic respiration in humans. Muscle contraction, contraction and relaxation in cardiac muscles and peristalsis are all carried out through aerobic respiration. Peptide bonds are formed for protein synthesis by aerobic respiration, growth, synthesis of chromosomes, synthesis of cell membranes are all carried out by aerobic respiration. The same process also carries out transmission of nerve impulse, along the axon by transporting sodium ions in and out of the membrane.

Anaerobic respiration is used in alcoholic fermentation, lactic acid fermentation and during rigorous muscular activity. Alcoholic fermentation is carried out in plants, where sugar is broken down to release energy.

Glucose ethanol + CO2 + energy of 2 ATP is released An economically important process that is used in bread making and brewing of beer and wine.

Some bacteria causes milk to turn sour and form yogurt. The bacteria feeds on sugar, which is then converted into lactic acid and energy. This energy is also equivalent to 2 ATP.

Glucose lactic acid + energy

During strenuous activity, breathing is not enough to provide sufficient oxygen for respiration. Muscles experience a shortage of oxygen, causing formation of lactic acid. Accumulation of lactic acid causes muscular cramps and fatigue. In turn, muscle experiences oxygen debt during periods of anaerobic respiration, rapid breathing helps to repay debt by increasing oxygen in the muscles. Thus, converting lactic acid back to glucose.

Thanks man you just helped me before my bio exam good job keep up the good work

BRILLIANT SUMMARY of both Aerobic & Anaerobic Respiration.. which now shifts (in some high school syllabue) to Alcohol Fermentation & Lactic Acid Fermentation

[TonyTigerTonyTiger]

2:14 Nope, wrong. The video confuses the anaerobic process of fermentation with anerobic respiration (the video also uses a long-outdated value for how many ATP are produced per starting glucose, and also makes some other mistakes.).

All respiration uses a respiratory chain, also called an electron transport chain, which has respiratory complexes in it; as electrons are passed from one complex to another in the electron transport chain, the small amounts of energy released are used to pump proton across the membrane, producing an electrochemical gradient that is then used by ATP synthase to synthesize ATP from ADP and Pi. That applies to both aerobic respiration and anaerobic respiration. The defining difference between aerobic respiration and anaerobic respiration is what the electron transport chain uses as its terminal electron acceptor: aerobic respiration uses molecular oxygen, and anaerobic respiration uses something else, such as sulfate, fumarate, nitrate, DMSO, etc.

Fermentation does not use a respiratory chain, does not produce an electrochemical gradients across a membrane, and does not use ATP synthase to produce ATP. Fermentation is NOT a form of anaerobic respiration.

Thank you I’m doing revision over the half term to try and catch up and this really helped thanks for explaining it so well I fully understand and my teacher will be impressed when I can explain the right process or respiration

[ovna]

Nice and well animated video! i think your logo can be better. (It's just my opinion)

[kronigen]

great animations! this is legit one of the best Indonesian-made animated science channel. keep on doing the good work, I immediately subbed.

[yessirmate]

Holy is this some Kurzgesagt level animation u deserve way more subs

[lukasmarkl]

Good explanation & animation of the processes, but respiration requires an electron transport chain with a final electron acceptor, like oxygen in aerobic respiration. For anaerobic respiration, e.g. nitrate or sulfate are used instead of oxygen, and is only found in procaryotes (propably because its less efficient). Therefore, fermentation is (striktly seen) not considered anaerobic respiration although it creates ATP without oxygen :)

[nutshell-wjtc]

I like your simple explanations of Cellular Respiration and other topics. I always watch at least one of your videos before exams. Thank you.

[venukia.]

as an 8th grader, this made my day
thanks

[أمايمانمجيدة]

Thank you very much for your wonderful explication

[Taym]

thank you, you helped me for my final exams

[clammyhands]

I needed this!! Thank you, this was so easy to understand.

[-aicfsjkriti.s]

Very nice explanation
Keep rock and post more
Thank u so much❤️🙏🙏🙏🙏🙏🙏

Narrated Al-Zubayr Ibn al-Awam that the Prophet (Sallallahu alaihi wa-sallam) said: “There has come to you the disease of the nations before you, jealousy and hatred. This is the ‘shaver’ (destroyer); I do not say that it shaves hair, but that it shaves (destroys) faith” [(Hasan) Jamee at-Tirmidhee]

[sunneweek]

As input, some parts of the animation still look too fast, making it difficult to see the text, and seem rushed. but overall, it's really cool

[Shawner_studios]

Thank to make this video! I relly need to study my exam!

[felixsfrindthatdintgivearawegg]

Aww man he couldn't catch that bus 😔😔

[juny_tae]

Aerobic respiration goes through many stages
1.Glycolysis
Where a molecule of glucose is changed to glucose 6 phosphate by converting an ATp to an ADp..then the carbon atoms of glucose 6 phosphate is rearranged to be easily broken to produce energy.. forming fructose 6 phosphate.. which also changes to fructose 1_6 diphosphate by converting another Atp to ADp..then fructose 1_6 diphosphate is split into two pgal molecules .. each pgal changes to a pyruvic acid by converting 2 ADP to 2 ATP and one NAD enzyme changes to NADH ...to give net products of the glycolysis ( 2ATP..2NADH and 2 pryrovic acid ) in cystole..which leads us to the following process
Of krybs cycle but I'm so lazy to write it

[bradkiller]

Thank you this video has helped me a lot . I'm about to write my board exams . 😑
