Question | Answer |
---|---|
What are the two types of activities that make up metabolism? | Catabolism, the breakdown of compounds into smaller simpler components, and anabolism, the building of simple compounds into needed substances. |
What name is given to the series of cellular reactions that releases energy from nutrients? | Cellular respiration |
What is the organic end product of glycolysis? | Pyruvic acid |
What element is required for aerobic cellular respiration but not for glycolysis? | Oxygen |
What is removed from amino acids before they are metabolized for energy? | Nitrogen |
What is the term for how rapidly a food raises the blood glucose level? | Glycemic index |
What is meant when an amino acid or a fatty acid is described as essential? | It cannot be made metabolically and must be taken in as part of diet. |
