During metabolism carbohydrates proteins and fat are burnt to create kilojulios, the energy is optained by hidrolizing ATP molecules.
Metabolic wastes or excretements are substances left over from metabolic processes (such as cellular respiration) which cannot be used by the organism (they are surplus or toxic), and must therefore be excreted. This includes nitrogen compounds, water, CO2, phosphates, sulphates, etc. Animals treat these compounds as excretes. Plants have chemical "machinery" which transforms some of them (primarily the nitrogen compounds) into useful substances. Some sustances are harmful such us Ammonotelism which is the excretion of ammonia and ammonium ions. Ammonia (NH3) forms with the oxidation of amino groups.(-NH2), which are removed from the proteins when they convert into carbohydrates. It is a very toxic substance to tissues and extremely soluble in water.
Imagine that you take a long, walk through the park, not running just walking.Your body will be undergoing anaerobic and aerobic metabolism, but provided you have eaten enough food that morning, are moving at a normal pace, and not overly exerting yourself, you probably won’t break a sweat or develop a lactic acid cramp. So long as the body’s aerobic metabolic pathways can keep up with the body’s demands, anaerobic metabolism can take a backseat. When the energy produced by aerobic processes is insufficient, the anaerobic processes take on a bigger role to fill the demand.
Congratulations, you have done a great job!
ReplyDeleteWhat is the energy unit used by the cell?Where does this energy unit come from?
What waste substances generate both metabolism?Is any of these substances harmful to the body?Why?
Can both metabolisms be used simultaneously to obtain energy?when?give an example.
