Context: It is possible with protein combinations of two incomplete protein sources (e.g., rice and beans) to make a complete protein source, and characteristic combinations are the basis of distinct cultural cooking traditions. However, complementary sources of protein do not need to be eaten at the same meal to be used together by the body. Excess amino acids from protein can be converted into glucose and used for fuel through a process called gluconeogenesis. The amino acids remaining after such conversion are discarded.

Question: What would be required for the human body to potentially have a chance to create a complete protein source?
Answer: two incomplete protein sources

Question: Other than rice, what would be another example of an incomplete protein source?
Answer: beans

Question: What is taken from proteins and converted to glucose by the body?
Answer: Excess amino acids

Question: What is the term for the conversion of amino acids into glucose?
Answer: gluconeogenesis

Question: What happens to amino acids that are left over after the body has converted what it can to glucose?
Answer: discarded
