| An exception to a dietary protein or one that is an animal protein but with little dietary protein source when eaten alone is called? | Gelatin |
| What is the primary function of protein in the diet? | To supply material for growth and maintenance. |
| What are the end products of proteins; they are absorbed as? | Amino acids |
| Protein catabolism would be increased in conditions such as illness. | True |
| What phase of metabolism makes growth and repair possible? | Anabolism |
| What are the end products of fat digestion? | Glycerol and fatty acids |
| What are the end products of protein digestion? | Amino acids |
| The sum aof all the chemical changes that an organism performs to maintain life and produce energy is the result of what process? | Metabolism |
| What are complementary proteins? | They provide higher quality protein when eaten together. |
| If the excretion of nitrogen exceeds the nitrogen intake, what is the condition called? | Negative nitrogen balance |
| What are triglycerides made up of? | Glycerol and fatty acids |
| What is an essential fatty acid? | One that the body cannont manufacture for itself. |
| What does the process of hydrogeneration do? | Adds hydrogen (liquid fats become solid fats) |

| List some foods that are high in protein | Breast milk, cows milk, eggs, cheese and meat, soybeans. |
| Describe negative nitrogen balance. | Occurs when the body takes in less nitrogen than it excretes. This means that the body has an inadequate protein intake and is loosing nitrogen by breaking down more tissue than it is building up. |
| What 4 elements make up the chemical compound "protein"? | Hydrogen, carbon, oxygen and nitrogen. |
| If the excretion of nitrogen exceeds the nitrogen intake, the conditon is called what? | Negative nitrogen balance |
