Studies also showed that by eliminating the sex differences that occur with the accumulation of adipose tissue by expressing metabolic rate per unit of "fat-free" or lean body weight‚ the values between sexes for basal metabolism are essentially the same. Exercise physiology textbooks have tables to show the conversion of height and body surface area as they relate to weight and basal metabolic

Worksheet 7-A: Metabolism Exercises Name __ _________________________ Metabolism explains how the cells in the body use nutrients to meet its needs. Cells may start with small‚ simple compounds and use them as building blocks to form larger‚ more complex structures (anabolism). These anabolic reactions involve doing work and so require energy. Alternatively‚ cells may break down large compounds into smaller ones (catabolism). Catabolic reactions usually release energy. Determine whether the

Adkins or Fadkins Case Study Part One – 1. Proteins - Proteins are chains of amino acids. In general‚ proteins may be structural proteins used to build tissues‚ they may be enzymes that mediate chemical reactions‚ or they may be hormones. Examples of proteins would be channel proteins in cell membranes‚ collagen protein in the skin‚ actin and myosin in the muscles‚ and hemoglobin in red blood cells. Types of dietary sources would be‚ meat‚ milk‚ (both of which are not pure proteins‚ but are

Biodegradation OF Xenobiotics . OVERVIEW Microorganisms play an important role in the removal of synthetic organic compounds from the environment. This chapter gives an overview of the evolution of biodegradation pathways and describes the strategies that microorganisms have evolved to transform important molecular structures. The actual effectiveness of biodegradation in the environment is determined by the bioavailability of the

Invertebrates are able to live in highly variable conditions due to their metabolism having evolved over time. Homeotherms are animals that are able to maintain a specific body temperature without relying on the temperature from its surroundings. Poikilotherms on the other hand do the exact opposite; their body temperature is influenced
