41 Actions of Hormones That Regulate Fuel Metabolism Many hormones affect fuel metabolism, including those that regulate appetite as well as those that influence absorption, transport, and oxidation of foodstuffs….
16 Use of Recombinant DNA Techniques in Medicine The rapid development of techniques in molecular biology is revolutionizing the practice of medicine. The potential uses of these techniques for the…
5 Structures of the Major Compounds of the Body Our body contains compounds of great structural diversity, ranging from relatively simple sugars and amino acids to enormously complex polymers such…
37 Synthesis and Degradation of Amino Acids Because each of the 20 common amino acids has a unique structure, their metabolic pathways differ. Despite this, some generalities do apply to…
13 Transcription: Synthesis of RNA Synthesis of RNA from a DNA template is called transcription. Genes are transcribed by enzymes called RNA polymerases that generate a single-stranded RNA identical in…
12 Synthesis of DNA DNA synthesis occurs by the process of replication. During replication, each of the two parental strands of DNA serves as a template for the synthesis of…
30 Oxidation of Fatty Acids and Ketone Bodies Fatty acids are a major fuel for humans and supply our energy needs between meals and during periods of increased demand, such…
17 The Molecular Biology of Cancer The term cancer applies to a group of diseases in which cells grow abnormally and form a malignant tumor. Malignant cells can invade nearby…
15 Regulation of Gene Expression Gene expression, the generation of a protein or RNA product from a particular gene, is controlled by complex mechanisms. Normally, only a fraction of the…
24 Oxidative Phosphorylation and Mitochondrial Function Energy from fuel oxidation is converted to the high-energy phosphate bonds of adenosine triphosphate (ATP) by the process of oxidative phosphorylation. Most of the…
