"it is possible to combine two or more plant proteins with different essential amino acids to yield a complete protein."
leonid [27]
Yes i believe it is possible. Complete proteins are proteins with all the indispensable amino acids present in proper proportions; for example in foods like eggs, meat, fish, milk. Incomplete proteins on the other hand are food proteins that contain a limiting amount of one or more indispensable amino acids needed for growth; for example corn tortillas are lacking in lysine. It is possible to make a complete protein by combining together two incomplete protein foods in the same meal.

Which of the following statements is true about the role of oxygen in cellular respiration?
ozzi
It is one of the beginning compounds.

This is the answer for many reasons. First off, it is not one of the ending compounds. It is only the end compound for photosynthesis. Second, it does not react to water as that is yet again photosynthesis. It does not react with carbon dioxide as carbon dioxide is what initially creates oxygen within cellular respiration.

Hope this helps!
