Whats the difference between breathing, aerobic respiartion and anarobic respiration?

Question

Plz be detailed soz bout spellin.

Answer 1

If this is for your GCSE next week I think it's high time you got hold of a textbook and read through the section on cellular respiration as if your very life depended on it, and started regretting all the messing about you did in class when you should have at least been making some bare essential notes on this stuff. Perhaps see if your local library opens sundays if you already lost / burnt your school textbook.

To be more helpful, in brief:

Breathing DOES NOT = "respiration". That's an old, outdated and confusing term for it that no-one should use any more (we now use "ventilation") .... yeah, i recognise this as something i had on my own GCSE years ago by the way :-)

Actual respiration is the act of metabolism, and in a vague sense, "living life" by the cell itself - the using up of raw materials ("food" e.g. glucose, and oxygen) to produce usable or storable energy (e.g. for movement, carrying out chemical reactions) and releasing less energetic waste materials (carbon dioxide, water).

Aerobic respiration releases a large amount of energy for each unit (eg molecule) of glucose supplied, as it uses oxygen (for what, don't worry for now, as that's degree-level stuff i still can't properly grasp... it accepts electrons, there you go :-) and allows the byproducts of early glycolysis to undergo conversion to pyruvate and enter the krebs cycle. You get... what was it... 18 molecules of energy-storing ATP out of each glucose molecule when it's involved this way.

Anaerobic respiration is a more basic, primitive form of getting energy from glucose (or similar molecules), where the reaction is pretty much that you take the glucose and split it into two fructose molecules, gaining 2 ATP in the process. That's it. No oxygen required, but some less friendly waste materials e.g. lactic acid are produced. This is mainly used in bacteria, which tend to find themselves in food-rich environments, have very little energy requirement for vigourous life, and few worries about buildup of waste materials .... it is also the reason you die if suffocated, and get pains in your legs if you overexert yourself - the body cells can't make enough energy from their limited glucose supplies to survive without using the krebs cycle, and the mass build up of lactic acid in oxygen-starved muscles is very damaging.

There you go hows that for a textbook answer. That'll be a bag of fizzy cola bottles please. Mmmmmm.
(That all came off the top of my head, but ONLY because i've been through that particular bloody mill four times so far - GCSE, A-Level, Biology degree and clinical training)

good luck

Answer 2

ok here is a hard working andwer based on looking at poorly people, aerobic respiration is still the bodies attempts to break down glucose for energy however without the presence of oxygen some nasty by products are left behind I'm not sure what the longterm effect of lactic acid would be i suspect muscular damage as the word acid suggests.

Answer 3

Aerobic respiation - the process in which the chemical bonds of energy-rich molecules such as glucose are converted into energy usable for life processes. Oxidation of organic material—in a bonfire, for example—is an exothermic reaction that releases a large amount of energy rather quickly. The equation for the oxidation of glucose is:

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy released (2830 kJ mol−1)
In a fire there is a massive uncontrolled release of energy as light and heat. Cellular respiration is the same process but it occurs in gradual steps that result in the conversion of the energy stored in glucose to usable chemical energy in the form of ATP. Waste products (CO2 + 6H2O) are released through exhaled air, sweat and urine.

Anaerobic Respiration - refers to the oxidation of molecules in the absence of oxygen to produce energy. These processes require another electron acceptor to replace oxygen. Anaerobic respiration is often used interchangeably with fermentation, especially when the glycolytic pathway exists in the cell. However, certain anaerobic prokaryotes generate all of their ATP using an electron transport system and ATP synthase.

The word & symbol equation for the anaerobic respiration of glucose is:

Glucose ---> Lactic Acid + Energy (ATP)

C6H12O6 ---> 2C3H6O3 + 2 ATP

The energy released is about 120kJ per mole Glucose.

Answer 4

well as this guy b4(klinkz i guess) me has already answered about aerobic respiartion and anarobic respiration and he did it pretty well..thats almost what i would've written but yes lemme tell ya that breathing is takin in n out of air(which i guess he didn't ans)
