what molecule do your cells use for energy? and will they produce which we exhale?

--> what do we expell from our body when we urinate as a result of aminoacid metabolism ?

chenglorraine, have you guessed the metabolic wastes yet? Those clues that sdekivit wrote you are very indicative :wink:.

Apart from the metabolic wastes that sdekivit wrote you in his clues, here I'm saying you two more: uric acid (by degradation of purines) and biliar pigments (by degradation of hemoglobyne). This two metabolic wastes are produced in the liver.

Another excretion product is something that we drink (which is essential for life) that is necessary for cell respiration and we excrete with urine, sweat (perspiration),...

Do you know it?

YES!~ I get it now! Is it UREA and CO2?

Yes, urea and CO2. The another one that I told you is water.

See ya! :wink:

Well, there are actually three ways in which an organism can rid itself of bodily waste, one is urea, as in humans, another is uric acid, which is common in the desert organisms such as camels, and the last is ammonia, but this is only used is organisms that live in aquatic environments due to it needing a lot of water to dilute it.
Saying that any two humans are exactly alike is like saying republicans have morals

Chemical digestion

Postby BiOKem » Thu Jan 05, 2006 7:52 pm

digestion of food materials begins in the mouth with both mechanically and chemically. For instance, starchy foods such as bread or potato must be chewed, and mixed with salivary enzymes. Digestive tasks involve the process occuring at the macro level(large polymers) and micro or molecular level. Though beginning in the mouth, the process does not end until the molecules of glucose are metabolized releasing energy and wastes products.

Example of non-competitive inhibition:

- The inhibition of G3P (glyceraldehyde-3-Phosphate) dehydrogenase by iodoacetamide:

Enzyme-SH + ICH2-CO-NH2 ---> Enzyme-SCH2-CO-NH2 + IH

- Also G3P dehydrogenase can be inhibited by iodoacetic acid:

Enzyme-SH + ICH2-COOH ---> Enzyme-SCH2-COOH + IH

Tell me how was your Biology test :wink:. See you!
