TAILIEUCHUNG - Biochemistry, 4th Edition P58

Biochemistry, 4th Edition P58. Continuing Garrett and Grisham's innovative conceptual and organizing framework, "Essential Questions," BIOCHEMISTRY guides students through course concepts in a way that reveals the beauty and usefulness of biochemistry in the everyday world. Streamlined for increased clarity and readability, this edition also includes new photos and illustrations that show the subject matter consistently throughout the text. New end-of-chapter problems, MCAT practice questions, and the unparalleled text/media integration with the power of CengageNOW round out this exceptional package, giving you the tools you need to both master course concepts and develop critical problem-solving skills you can draw upon. | Further Reading 533 tial end products are provided. Then the biochemical consequences of the mutation can be investigated. What Can the Metabolome Tell Us about a Biological System Rapid advances in chemical analysis have made it possible to carry out comprehensive studies of the many metabolites in a living organism. The metabolome is the complete set of low-molecular-weight molecules present in an organism or excreted by it under a given set of physiological conditions. Metabolomics is the systematic identification and quanti tation of all these metabolites in a given organism or sample. Mass spectrometry offers unmatched sensitivity for detection of metabolites at very low concentrations whereas NMR spectroscopy can provide remarkable resolution and discrimination of metabolites in complex mixtures. What Food Substances Form the Basis of Human Nutrition In addition to essential fiber the food that human beings require includes the macronutrients protein carbohydrate and lipid and the micronutrients including vitamins and minerals.

If 3 X 1014 kg of CO2 are cycled through the biosphere annually how many human equivalents 70-kg people composed of 18 carbon by weight could be produced each year from this amount of CO2 2. Define the differences in carbon and energy metabolism between photoautotrophs and photoheterotrophs and between chemoautotrophs and chemoheterotrophs. 3. Name three principal inorganic sources of oxygen atoms that are commonly available in the inanimate environment and readily accessible to the biosphere. 4. What are the features that generally distinguish pathways of catabolism from pathways of anabolism 5. Name the three principal modes of enzyme organization in metabolic pathways. 6. Why is the pathway for the biosynthesis of a biomolecule at least partially different from the pathway for its catabolism Why is the pathway
