Question
TRUE or FALSE
- Glycerol that is liberated from fats is digested by passing through glycolysis. ____
- As a general rule, NADPH is produced by catabolic reactions, and NADH is the reducing agent of biosynthetic reactions. ____
- The synthesis of amino acids and the intake of amino acids are both important in order to replace cells lost from cellular death caused by either old age of the cells or disease. ____
- Once the amino group is removed from an amino acid, the carbon skeleton is passed into the citric acid cycle. ____
- Energy is generally consumed during anabolism. ____
- A function of ATP is to provide the energy for the movement of materials across the cell membrane
Explanation / Answer
1. True. Glycerol is metabolized into an intermediate, dihydroxyacetone phosphate in glycolysis which ends up forming pyruvic acid.
2. True. NADPH molecules are created in catabolism when a negative hydride anion is bonded to a molecule of NADP+.NADH is giving up a H- in the reaction which means it is giving up electrons, and is the reducing agent.
3. True. The intake and synthesis of amino acid are important for the growth, regeneration and maintenance of the body tissues and muscles. They are necessary for formation of different proteins in the body.
4. True. Once the deamination process is complete, carbon Skeleton takes converts in to major metabolic intermediates that can be converted in to glucose and hence enters citric acid cycle.
5. True. Anabolism is the process by which body utilizes the energy released by catabolism to synthesize complex molecules.
6. True. ATP is the energy currency of the cell that can provide enough amount of energy for the smooth movement of materials across the cell by converting in to ADP.
