Single plant-derived proteins (beans, lentils, etc.).
C.
Single sources of either plant- or animal-derived proteins.

C.
Single sources of either plant- or animal-derived proteins.

Explanation / Answer
2) 9 out of 20 amino acids are required to build up as they cannot be made by the body and has to be taken outside from the body in the diet..!!
3) the answer is Gluconeogensis.. It is the process or the reverse of glycolysis which results in the formation of the glucose in the body from the non carbohydrates sources..!!
5) the first reserve of the very early fasting conditions the source is glycogen reserve as they are broken down to glucose to provide energy..!!
6) the excess protein results in the formation of the ketone bodies as some protein are ketogenic in nature and results in ketone formation. Hence more protein, more breakage, more ketone bodies..!
